The Ugly Truth About Coffee’s Effects On Your Body

Is Caffeine Good or Bad for You?

Are you a regular coffee drinker? Do you sometimes worry that caffeine might be bad for your health? Well, there’s no need to feel guilty about your little coffee habit.  In fact, caffeine has been found to have a lot of positive health benefits and, despite what you may have heard, relatively few drawbacks.

Positive effects of caffeine

People who drink coffee every day have a significantly lower risk of diabetes, Parkinson’s, colon cancer, gallstones, and Alzheimer’s disease. Now, that may not all be due to caffeine. Coffee contains a lot of volatile compounds and antioxidants that may have beneficial effects by themselves, or in combination with caffeine.

For example, drinking tea doesn’t seem to reduce your risk of diabetes, even though tea contains caffeine. On the other hand, people who drink decaffeinated coffee do have a reduced risk, but decaf only seems to work about half as well as caffeinated coffee.

It’s definitely the caffeine that protects against Parkinson’s and Alzheimer’s, though. Not only does caffeine stimulate the brain and central nervous system, but it appears to protect it as well. Caffeine doesn’t make you any smarter but it does makes you more alert and boosts your ability to concentrate, which can make you a better test taker or a better driver.

The benefits of caffeine start kicking in when you consume a cup of coffee or a couple of cups of black tea every day. The positive effects really start piling up when you drink three or four cups of coffee a day or the equivalent. People who drink seven or eight cups a day may get even a little more benefit in terms of neuroprotection, but also have a higher risk of ill effects, such as jitters, agitation, or sleep disruption.

Does caffeine cause or treat headaches?

Caffeine can also relieve headaches. In fact, the popular headache medicine Excedrin contains as much caffeine as a big cup of coffee.  Headaches, especially tension-type headaches, are often accompanied by increased blood flow to the brain. Ths puts pressure on the nerves and causes pain. Caffeine is a vasoconstrictor, meaning that it constricts blood vessels, and this can relieve headache pain. In fact, adding caffeine to a pain reliever like Tylenol can increase the effectiveness by up to 40%. 

If you drink coffee, tea, or other caffeinated beverages regularly, stopping suddenly can also bring on a headache. In fact, it's hypothesized that caffeine withdrawal may contribute to post-operative pain -- because patients typically skip their regular morning cup on the day of surgery. And one study even found that adding a bit of caffeine to the IV liquid for patients recovering from surgery made them quite a bit more comfortable! It can also help people shake off the effects of anesthesia more quickly.

Does caffeine make you a better athlete?

Caffeine also enhances athletic performance. In fact, up until recently, caffeine was considered a performance-enhancing drug by the International Olympic Committee and athletes had to keep their intake of caffeinated beverages fairly low to pass their drug screens. Unlike most performance-enhancing drugs, you can safely try this one at home. Have a cup or two of coffee one hour before your workout and you may be able to go a bit faster, stronger, and longer. This effect may be enhanced if you abstain from coffee for a week or two.

Brock Armstrong of the Get-Fit Guy podcast recently dedicated an episode to using caffeine to enhance your athletic performance.

Myths about caffeine

Many of the negative things you’ve heard about caffeine are actually myths, several of which I’ve debunked in previous shows. It’s a myth, for example, that caffeine weakens your bones, as I explained in my episode on nutrition for healthy bones.

It's also a myth that caffeine consumption is liked to fibrocystic changes, or benign lumps, in the breast. Trial after trial has found no connection between caffeine or coffee consumption and breast lumps or fibrocystic breast disease.  Women who suffer is 100 mg of caffeine bad for you breast pain and tenderness are often counseled to give up caffeine. And one small study found that 61% of women who cut out (or cut down on) caffeine had improvement of their symptoms. However, this study included no control group. And other research has found that breast pain tends to resolve on its own after a few months. So it's impossible to say whether avoiding caffeine was responsible for the reduction of breast pain.  

And, as I explained in the dehydration myth episode, caffeinated beverages are not dehydrating. Caffeine is a diuretic, meaning that it makes you pee more. But the fluids in coffee and tea more than replace any fluids that you lose due to the diuretic effect. Not only that, but if you drink coffee regularly, it loses it's diuretic effects.

Keep in mind, though, that caffeine pills don’t contain any fluids and, therefore, can be dehydrating.

Finally, you might have heard that caffeine or coffee is bad for your heart. Some studies have found that drinking unfiltered coffee—such as French press or percolated coffee—elevates cholesterol. It appears to be volatile oils in the coffee rather than caffeine that affect cholesterol, and only in men. But coffee drinkers are no more likely to develop heart disease.

Coffee can also cause a temporary increase in your blood pressure but this is not thought to be a concern.  And although caffeinated coffee can also temporarily increase your heart rate a bit, it does not cause irregular heartbeat. In fact, an as yet unpublished study presented at the meeting of the Heart Rhythm Society found that coffee consumption is associated with a lower risk of arrythmias.

Negative effects of caffeine

There are some legitimate downsides of caffeine but they are relatively minor. Some people find that caffeines make them jittery, anxious, or disrupts their sleep. How many cups of coffee it takes to make your hair stand on end, or how late in the day you can drink a cup of coffee without staring at the ceiling all night, are subject to a high degree of individual variation.

People who are very sensitive to stimulants are usually better off avoiding caffeine altogether.  For everyone else, moderate consumption of caffeine appears to have a lot of benefits and limited disadvantages. The alert listener will have noted that I have once again invoked the “M” word: Moderation. Here are your parameters for moderate caffeine consumption:

How much caffeine is too much? 

National health advisory committees in The U.S., Canada, and Europe agree that mg of caffeine per day is perfectly safe for most healthy people. That's the amount you'd get in cups of brewed coffee. (Some energy drinks have up to mg per can.) 

Large amounts of caffeine could negatively affect the growth and development of babies in the womb. Women who are pregnant, planning to become pregnant, or breastfeeding are advised to limit their intake to mg per day or less.

Under normal circumstances, it takes about 5 hours for half of the caffeine you consume to be cleared from your system. Because caffeine can negatively affect sleep quality, you're well advised to avoid drinking caffeinated beverages with 5 to 8 hours of bedtime.

There's really not a lot of data on safe amounts of caffeine for kids or adolescents, which is a concern given the popularity of high-caffeine energy drinks. Some agencies have recommended that kids keep their caffeine intake well under mg per day, which would be the amount in two cans of caffeinated soda. Other experts feel that even that might be unwise. 

What is caffeine found in?

Coffee is the primary source of caffeine in the American diet. (Interestingly, it's also the primary source of antioxidants--by a large margin!)  But varying amounts of caffeine are also found in black and green tea, soda, energy drinks, chocolate, as well as some over-the-counter pain relievers and dietary supplements.

The headline is shocking: &#;South Carolina Teen Died from Caffeine Overdose.&#; It almost seems impossible. The truth is though that exposure to high and even deadly levels of caffeine is more common &#; and happens more easily &#; than you may expect. &#;Many people who drink too much caffeine experience the jittery feeling but might not call to report or seek out medical care,&#; said Barbara Crouch, PharmD, executive director of the Utah Poison Control Center. &#;I think there are many folks who definitely take in too much &#; even if it is not an &#;overdose.&#;&#;

Part of the reason it is so easy to ingest too much caffeine is that it is in so many things. There is caffeine in coffee, tea, soft drinks, pain killers, energy drinks, chocolate, and even bagels. You may be taking too much caffeine without even knowing it &#; and you may start feeling the ill effects. &#;Energy drinks have large amounts of caffeine &#; add caffeinated soft drinks and/or strong coffee drinks; dietary supplements with various natural and synthetic caffeine and you can get into trouble relatively easily,&#; said Crouch. &#;You start feeling jittery, tremulous, probably nausea, maybe vomiting and perhaps some heart palpitations.&#;

Another issue is it can be difficult to determine how much caffeine is too much until those jittery feelings begin. The amount of caffeine consumed, the time frame, and the body composition of the person consuming the caffeine all play a part. It also depends on what you are considering too much. is 100 mg of caffeine bad for you depends on whether you are looking at adverse effects, moderate toxicity or fatal outcomes,&#; said Crouch. &#;Dosing for fatigue is mg every hours &#; and anything that exceeds that is likely to be problematic.&#;

In the most severe cases of caffeine toxicity, the heart and nervous system can be impacted. The South Carolina teen whose death is linked to caffeine went into cardiac arrest. &#;As a stimulant, caffeine increases heart rate as well as causes disturbances in the rhythm of the heart.&#; It can also lower blood pressure in high doses,&#; said Crouch. &#;It also stimulates the central nervous system &#; that&#;s the jittery feeling &#; which can lead to agitation and ultimately can cause delirium and seizures.&#;

In these severe cases, measures can be taken to try to reduce the impacts &#; but there is nothing that can be done to reverse the caffeine toxicity. Unfortunately that only happens as the body metabolizes the caffeine and pushes it out of the body through waste products. &#;Serious toxicity we use supportive measures &#; means to lower heart rate if necessary; means to support blood pressure and anticonvulsants if someone seizes,&#; said Crouch. &#;To keep them out of danger until the caffeine leaves their system.&#;

The best way to avoid potential caffeine complications is to watch your intake. If you think you have had too much, you probably have. And remember, if you are fatigued your body probably needs rest &#; not another cup of coffee.&#;

Caffeine is a natural stimulant that enhances dopamine signaling in the brain. Dopamine is a chemical in the brain which helps control movement, motivation, and emotions, so enhanced dopamine signaling makes is 100 mg of caffeine bad for you person feel more awake and alert. This alert and awake feeling is why caffeine is classified as a stimulant.

The effects of caffeine usually reach their peak level in the blood about an hour after consumption. Individuals may continue to feel the effects of caffeine pills for four to six hours afterward.

The Dangers Of Abusing Caffeine Pills

Although caffeine can cause an increase in dopamine, it does not cause unnatural imbalances in the reward circuits in the brain which is necessary for an addiction. So, although many people claim to be &#;addicted&#; to their morning coffee or daily caffeine pill, they are actually dependent is 100 mg of caffeine bad for you them, not addicted.

Combining caffeine with other substances, particularly &#;downers&#; like alcohol can be dangerous. When alcohol is mixed with caffeine, the caffeine can hide the depressant side effects of alcohol which can cause people to drink more, believing they can handle it.

Other substances that should not be combined with caffeine pills include other stimulants, certain antibiotics, asthma medications, and heart medications. Talk to a healthcare professional before consuming the above substances with caffeine as the results can be potentially life-threatening.

Symptoms Of Caffeine Pill Abuse

Caffeine pills may not be addictive, but that doesn&#;t necessarily make them safe. Like any other substance, people may abuse caffeine pills. Too much caffeine can be toxic to the body and cause unpleasant or unwanted side effects.

There is a wide range of effects caffeine can have on the body&#;s metabolism. Caffeine can stimulate the central nervous system, act as a diuretic, increase the release of acids in the stomach, and increase blood pressure.

For most people, it is not harmful to consume up to mg of caffeine a day. However, consuming higher doses of caffeine can cause unpleasant symptoms such as:

  • restlessness, shakiness, and jitters
  • insomnia
  • headaches
  • dizziness
  • rapid or abnormal heart rhythm
  • dehydration
  • anxiety
  • dependency, so that more caffeine is needed to feel its effects

Caffeine Pills: How Much Caffeine Is Too Much?

There is a wide variation in how sensitive people are to the effects of caffeine and how fast they metabolize it. These factors can make it difficult to say precisely how much caffeine is too much for one person to consume.

Certain conditions tend to make people more sensitive to caffeine, as can other medications. The FDA has cited that mg of caffeine is safe for healthy adults, but they have not set a recommended level for children. Many still discourage the consumption of caffeine and other stimulants by children or adolescents including the American Academy of Pediatrics.

People who should avoid or limit caffeine include:

  • Pregnant and breastfeeding women. As the caffeine can pass through the placenta or breast milk and affect the baby negatively.
  • Individuals with sleeping disorders. Excess caffeine may increase problems with sleeping cycles.
  • People with chronic migraines or other headaches. Caffeine consumption can increase the amount and severity of these headaches.
  • Individuals with anxiety, ulcers, or GERD. Caffeine may increase the severity of these conditions.
  • People with high blood pressure. Consuming caffeine can increase blood pressure to dangerous levels.

Can You Overdose On Caffeine Pills?

Although it is rare, it is possible for someone to overdose on caffeine pills. A toxic dose of caffeine is considered to be five or more grams. Caffeine pills and other over-the-counter supplements, which are typically used to combat fatigue, generally contain mg caffeine per tablet.

Ingesting too many caffeine pills may cause fatal caffeine intoxication.

Symptoms of caffeine overdose may include:

  • arrhythmia
  • tachycardia
  • vomiting
  • convulsions
  • coma
  • possible death

Caffeine Pill Withdrawal

It may not be possible to become addicted to caffeine pills, but once someone develops a dependency on caffeine, they can experience withdrawal unemployment card services phone number. Suddenly stopping consuming caffeine pills, after taking them regularly, can cause individuals to experience symptoms of caffeine withdrawal such as:

  • headaches
  • drowsiness
  • irritability
  • nausea
  • difficulty concentrating

Depending on the individuals&#; tolerance to caffeine, these symptoms can last for a few hours up to three days.

How To Stop Taking Caffeine Pills Without Causing Unwanted Side Effects

Individuals who consume caffeine pills daily but want to cut back should do so gradually. It is never a good idea to stop medications suddenly as it can send the body into a state of shock.

Unlike opioid or alcohol withdrawal, caffeine withdrawal is not considered to be particularly dangerous. However, if someone is dependent on other substance in addition to caffeine, their caffeine dependence may influence the way they experience withdrawal from one or both substances.

In these cases, the additional help of an inpatient treatment program may be required. While withdrawing from caffeine may not be dangerous, it can be unpleasant and talking to a healthcare professional can help you figure out how to cut back.

The recent death of a South Carolina teen blamed on too much caffeine has once again propelled the popular stimulant and questions over its safety into the national spotlight.

Sixteen-year-old Davis Cripe collapsed last month at his high school and died at a hospital after consuming a large soft drink, a latte and an energy drink over a short period, according to Richland County coroner Gary Watts.

Davis was a healthy and active teen who shunned drugs and alcohol, his parents said.

A classmate who was with Davis the day he died said he "basically chugged" an energy drink during class, CBS News correspondent Tony Dokoupil reports.

"These drinks, this amount of caffeine, how it's ingested can have dire consequences and that's what happened in this case," Watts said.

Watts determined the high school sophomore experienced a "cardiac event" after consuming so much caffeine in less than is 100 mg of caffeine bad for you two-hour span.

Over the last few years, there have been several highly publicized deaths attributed to caffeine overdose — particularly in healthy teens and young adults — raising questions about the safety of America's favorite stimulant. 

11 things you should know about caffeine

There have also been new challenges for state and federal health officials and lawmakers struggling with how to regulate and control the sales of certain novel, highly caffeinated products, including Four Loko, a caffeine-spiked alcoholic drink which was banned in several states and reformulated under pressure from the FDA in It no longer contains caffeine.

Though caffeine itself is of course legal and widely used, caffeine is still a stimulant drug. It is generally very safe for most people, but consuming too much of it can be dangerous.

According to the Mayo Clinic, up to milligrams of caffeine a day appears to be safe for most healthy adults. That's about the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks. 

Consuming more than that could start to affect your health.

"You know it when it happens. You start to feel dizzy. You can feel it in your chest," said CBS News medical contributor Dr. David Agus. 

A major issue is that many people may not realize how much caffeine is in the beverages they consume.

According to the Center for Science in the Public Interest, a venti Starbucks Blonde Roast contains mg of caffeine, while a 2 oz. 5-hour Energy Shot contains mg. Most 16 oz. energy drinks, including Monster, Rockstar, and Venom, contain mg.

Agus says energy drinks send more than 20, people to the emergency room annually.

"The problem that we're learning is that it's not just caffeine, it's the other stimulants that are in there," he told "CBS This Morning" Tuesday. "In a cup of coffee, you may have [it] over 45 minutes or 60 minutes. These energy drinks you're having all at once. And so all the caffeine give this big peak in the body and that's when bad things happen."

Other ingredients in energy drinks vary, but can include herbal substances, vitamins, sugars, and taurine, an amino acid found in meat and fish.

Inthe FDA announced it was investigating five deaths linked to Monster Energy Drinks.

The American Academy of Pediatrics advises against children and teens drinking energy drinks of any kind.

CBS News contacted the American Beverage Association, which represents the makers of almost all energy drinks sold in America, and they referred us to their fact sheet on caffeine. The trade group says energy drinks can be safely consumed in moderation.

Caffeine and Sleep: Does Caffeine Affect Sleep?

By: SleepScore Labs  

Caffeine: The athlete's (mostly) legal performance booster

Cup of steaming coffee resting on coffee beans It is one of the key components in energy drinks, coffee and some medication.

Because of its widespread consumption, many don’t consider caffeine a drug, but it is.

Arizona State University nutrition lecturer Christina Barth looks at caffeine as steroids before steroids were the dominant performance-enhancing substance in baseball.

“I used to work in (Major League Baseball), and I saw the whole story of caffeine really gaining publicity back then,” Barth said.

For the average person, caffeine is often used as a pick-me-up; some drink up to three cups of coffee a day. For athletes, there is a more strategic use.

“Caffeine stimulates the central nervous system to reduce fatigue and drowsiness. It may also benefit exercise performance; research has shown that it can improve endurance and increase muscular strength,” wrote Honor Whiteman in an article on Medical News Today.

Murray Carpenter wrote in the The Atlantic that Sarah Piampiano, the second American woman finisher at Ironman U.S. Championship in Manhattan, “has maybe two cups of coffee in a year, because she is sensitive to its effects. But on race day, she uses it thoughtfully and systematically to optimize her performance.”

“She uses energy gels made by Clif Bar, one of her sponsors, to integrate calories and caffeine into her race-day nutrition plan,” Carpenter said. “Before the race, she usually takes a gel with 50 milligrams of caffeine. Then on the biking leg, she takes 50 milligrams per hour. And that increases later in the race.”

“As you get further into the marathon, your energy supplies are depleted and you just really start suffering; that’s why I start increasing the amount of caffeine I take. At the end of the marathon, you need that energy kick,” said Piampiano.

Peter Vervoort, a physician from Belgium, studied caffeine in athletes in Antwerp and said in The Atlantic doses of to milligrams were not helpful, especially in hot weather.

Vervoort, who also competed in the Ironman, said it is becoming difficult to avoid caffeine on the race course because more gel companies only make gels with caffeine.  

“In moderation, I think caffeine for athletes can be safe and it can actually enhance their performance,” Barth said. “But the issue with caffeine is that once we get up to a is 100 mg of caffeine bad for you amount our bodies get accustomed to that and then we need more and more of the caffeine to get the same effect.”

Although Piampiano’s caffeine intake may not be excessive, researchers Matthew S. Ganio, Jennifer F. Klau, Douglas J. Casa, Lawrence E. Armstrong and Carl M. Maresh — who were at the University of Connecticut, in Storrs, Conn., at the time — studied the “Effect of Caffeine on Sport-Specific Endurance Performance” and published their findings in The Journal of Strength and Conditioning Research.

“Caffeine seems to be equally effective when ingested in combination with carbohydrate-electrolyte solutions (e.g., sports drinks) or other modes of ingestion (e.g., gum), but other substances in caffeinated-coffee may is 100 mg of caffeine bad for you caffeine performance-improving properties,” according to the researchers.

The researchers recommended athletes abstain from caffeine for no less than seven days before its use in competition because individuals react differently to caffeine. It is recommended athletes try caffeine while training before using it in competition.

There is no denying caffeine can improve exercise performance both before and during competition. A NPR report quoted Mark Glaister, an exercise physiologist at St. Mary’s University in Twickenham, U.K., saying it “helps pretty much every kind of endurance exercise, giving a performance advantage of percent to 5 percent.”

The NPR report also noted that despite the confirmed performance enhancing qualities, caffeine is not on the World Anti-Doping Agency’s banned list. For 20 years (), caffeine, if found at high enough levels in Olympic athletes, was subject to sanction. Today, it remains on the World Anti-Doping Agency’s watch list and its levels in athletes are tracked.

Katherine Hobson, the author of the NPR story, wrote “athletes see a benefit with a dose of between 3 to 6 mg per kg of body weight, which means that if a pound cyclist were drinking an average cup of coffee, he’d get a lift after drinking about two to four cups. (Many brands of coffee have a lot more caffeine than the average of about mg per cup, though.) It takes 30 to 60 minutes for caffeine levels to peak in the body and provide the biggest benefit.”

For some athletes just enough might make you pick up the pace, but Glaister said too much is a bad idea.

Barth recommends mg or less per day is best for athletes because levels greater than mg per day can become addicting and negative side effects start to happen.

According to Glaister in the NPR report: Even non-dangerous doses can cause anxiety, sleeplessness and restlessness, and large amounts can be dangerous and even deadly.

According to Sports, Cardiovascular, and Wellness Nutrition documentation published by the  NCAA Sport Science Institute entitled “Effects of Too Much Caffeine on Athletic Performance” consuming amounts in excess of mg per day can lead to adverse side effects, and at very high levels of consumption ( mg) an athlete can test positive for caffeine as a banned substance by the NCAA.

In order to test positive for the banned substance, an NCAA athlete would need to reach a “urinary caffeine threshold level of 15 mcg/mL that equals to approximately six to eight cups of brewed coffee is 100 mg of caffeine bad for you mg/8 oz) two to three hours prior to competition,” according to the NCAA.

“In laboratory settings, caffeine consumption at levels recognized as safe ( mg/kg) one hour prior to and during sub-maximal endurance training and high intensity and cardiovascular exercise up to 20 minutes, has shown improvement performance,” according to the NCAA document.

Athletes that use coffee excessively but want to stop completely Barth said the smarter route is gradually cutting caffeine back, not going cold turkey because it will send a shock to your body and brain.

“It really affects our neurotransmitters in our brain and that's why there’s this effect to why people feel really tired, they get headaches,” Barth said.

  February 10th,

Every morning, you walk downstairs and head for that glistening coffee pot to make a steaming hot cup of joe. However good that first cup of morning coffee tastes, the feeling that comes from drinking coffee can be even more enticing. Caffeine is a stimulant with powerful physical and mental effects. To maintain healthy sleep, it’s important to understand how caffeine and other stimulants affect the body, and how to manage their consumption to avoid sleep problems.

Caffeine stimulates your body’s central nervous system, increasing alertness and reducing fatigue. Once ingested, caffeine takes effect within 15 to 20 minutes, and half of that caffeine can remain in your system for can last for six or more hours. This is what experts describe as caffeine&#;s half-life, and it is not a fixed figure. It is the amount of time it takes caffeine to work its way out of your system. This can vary from four to six hours, or more, but seems to average around hours.

How would that look in real time? As one expert warns, &#;if you consume mg of caffeine at mid-day, you would still have mg in you at around pm.&#; This starts to explain just how and why coffee can impair healthy sleep.

What Does Caffeine Do to your Body?

It’s important to be aware of how caffeine affects your body. For instance, a mid-afternoon cup of coffee may interfere with your ability to fall asleep many hours later. Your individual sleep-wake routine also will play a role in the timing of your caffeine consumption. If you’re an early-to-bed person, a 3 PM cup of coffee may upset your normal sleep regimen. To avoid nightly sleep disruptions due to caffeine, work back 10 hours from bedtime to find your caffeine cut-off time.

Caffeine also stimulates the production of adrenaline, an alertness-boosting hormone that is linked to your body’s fight or flight response. An increase in adrenaline raises your heart rate, increases your breathing and brings on a state of increased vigilance and alertness. Caffeine also blocks the effectiveness of adenosine, a chemical that helps to bring on drowsiness and to regulate your sleep-wake cycles. Additionally, caffeine alters sleep architecture, the overall nightly distribution of sleep among the five different sleep stages. Over-caffeinating can reduce time spent in deep sleep, the phase that is critical for physical and mental rejuvenation.

What Steps Can You Take?

Moderation is definitely the key to kicking your sleep deprivation that’s caused by drinking too much caffeine. That morning cup of coffee is fine, so long as you’re not having trouble sleeping at night. Many people can manage moderate caffeine consumption early in the day without compromising sleep. A general guideline is to curtail caffeine consumption by 2 PM.

Another great strategy is to monitor how much caffeine you’re actually drinking each day. Start the day with the most highly caffeinated beverage, and gradually taper down from there. Switch to a half-regular, half-decaf cup of coffee, or to tea, before forgoing caffeine altogether for the remainder of the day. It’s also important to remember the amount of caffeine in popular drinks can vary widely. An 8-ounce cup of coffee contains approximately milligrams or more of caffeine. A latte can typically have anywhere from 60 mg of caffeine, while a single ounce espresso may have between mg. Cola drinks usually have between mg of caffeine, while an 8-ounce cup of green tea contains mg of caffeine.

If you decide to give up caffeine altogether, try eliminating it gradually. Giving up caffeine abruptly can lead to fatigue and sluggishness, and may cause headaches. These effects are short-term and won’t have any lasting consequences to your overall performance. Nevertheless, it can be easier and less disruptive to gradually taper down your caffeine consumption.

Other Stimulants that Cause Sleep Issues

Caffeine isn’t the only stimulant that can pose problems to sleep. Sugar and nicotine are two other common stimulants associated with sleep difficulties. Consuming too much sugar and eating high-sugar foods too close to bedtime can interfere with sleep. High-sugar foods cause blood sugar levels to fluctuate sharply. During the day, these fluctuations can lead to fatigue, which can cause sleep problems at night.

Nicotine stimulates adrenaline, elevating heart rate and breathing. Smoking or chewing tobacco near bedtime can make it more difficult to fall asleep and can reduce time spent in REM sleep. It can also irritate and inflame the tissues of the nose and throat, which can lead to snoring affecting your sleep quality.

Moderating consumption of caffeine and other stimulants is an essential part of a strong daily sleep routine and a long-term plan for sleep health.

  February 10th,

Every morning, you walk downstairs and head for that glistening coffee pot to make a steaming hot cup of joe. However good that first cup of morning coffee tastes, the feeling that comes from drinking coffee can be even more enticing. Caffeine is a stimulant with powerful physical and mental effects. To maintain healthy sleep, it’s important to understand how caffeine and other stimulants affect the body, and how to manage their consumption to avoid sleep problems.

Caffeine stimulates your body’s central nervous system, increasing alertness and reducing fatigue. Once ingested, caffeine takes effect within 15 to 20 minutes, and half of that caffeine can remain in your system for can last for six or more hours. This is what experts describe as caffeine&#;s half-life, and it is not a fixed figure. It is the amount of time it takes caffeine to work its way out of your system. This can vary from four to six hours, or more, but seems to average around hours.

How would that look in real time? As one expert warns, &#;if you consume mg of caffeine at mid-day, you would still have mg in you at around pm.&#; This starts to explain just how and why coffee can impair healthy sleep.

What Does Caffeine Do to your Body?

It’s important to be aware of how caffeine affects your body. For instance, a mid-afternoon cup of coffee may interfere with your ability to fall asleep many hours later. Your individual sleep-wake routine also will play a role in the timing of your caffeine consumption. If you’re an early-to-bed person, a 3 PM cup of coffee may upset your normal sleep regimen. To avoid nightly sleep disruptions due to caffeine, work back 10 hours from bedtime to find your caffeine cut-off time.

Caffeine also stimulates the production of adrenaline, an alertness-boosting hormone that is linked to your body’s fight or flight response. An increase in adrenaline raises your heart rate, increases your breathing and brings on a state of increased vigilance and alertness. Caffeine also blocks the effectiveness of adenosine, a chemical that helps to bring on drowsiness and to regulate your sleep-wake cycles. Additionally, caffeine alters sleep architecture, the overall nightly distribution of sleep among the five different sleep stages. Over-caffeinating can reduce time spent in deep sleep, the phase that is critical for physical and mental rejuvenation.

What Steps Can You Take?

Moderation is definitely the key to kicking your sleep deprivation that’s caused by drinking too much caffeine. That morning cup of coffee is fine, so long as you’re not having trouble sleeping at night. Many people can manage moderate caffeine consumption early in the day without compromising sleep. A general guideline is to curtail caffeine consumption by 2 PM.

Another great strategy is to monitor how much caffeine you’re actually drinking each day. Start the day with the most highly caffeinated beverage, and gradually taper down from there. Switch to a half-regular, half-decaf cup of coffee, or to tea, before forgoing caffeine altogether for the remainder of the day. It’s also important to remember the amount of caffeine in popular drinks can vary widely. An 8-ounce cup of coffee contains approximately milligrams or more of caffeine. A latte can typically have anywhere from 60 mg of caffeine, while a single ounce espresso may have between mg. Cola drinks usually have between mg of caffeine, while an 8-ounce cup of green tea contains mg of caffeine.

If you decide to give up caffeine altogether, try eliminating it gradually. Giving up caffeine abruptly can lead to fatigue and sluggishness, and may cause headaches. These effects are short-term and won’t have any lasting consequences to your overall performance. Nevertheless, it can be easier and less disruptive to gradually taper down your caffeine consumption.

Other Stimulants that Cause Sleep Issues

Caffeine isn’t the only stimulant that can pose problems to sleep. Sugar and nicotine are two other common stimulants associated with sleep difficulties. Consuming too much sugar and eating high-sugar foods too close to bedtime can interfere with sleep. High-sugar foods cause blood sugar levels to fluctuate sharply. During the day, these fluctuations can lead to fatigue, which can cause sleep problems at night.

Nicotine stimulates adrenaline, elevating heart rate and breathing. Smoking or chewing tobacco near bedtime can make it more difficult to fall asleep and can reduce time spent in REM sleep. It can also irritate and inflame the tissues of the nose and throat, which can lead to snoring affecting your sleep quality.

Moderating consumption of caffeine and other stimulants is an essential part of a strong daily sleep routine and a long-term plan for sleep health.

The headline is shocking: &#;South Carolina Teen Died from Caffeine Overdose.&#; It almost seems impossible. The truth is though that exposure to high and even deadly levels of caffeine is more common &#; and happens more easily &#; than you may expect. &#;Many people who drink too much caffeine experience the jittery feeling but might not call to report or seek out medical care,&#; said Barbara Crouch, PharmD, executive director of the Utah Poison Control Center. &#;I think there are many folks who definitely take in too much &#; even if it is not an &#;overdose.&#;&#;

Part of the reason it is so easy to ingest too much caffeine is that it is in so many things. There is caffeine in coffee, tea, soft drinks, pain killers, energy drinks, chocolate, and even bagels. You may be taking too much caffeine without even knowing it &#; and you may start feeling the ill effects. &#;Energy drinks have large amounts of caffeine &#; add caffeinated soft drinks and/or strong coffee drinks; dietary supplements with various natural and synthetic caffeine and you can get into trouble relatively easily,&#; said Crouch. &#;You start feeling jittery, tremulous, probably nausea, maybe vomiting and perhaps some heart palpitations.&#;

Another issue is it can be difficult to determine how much caffeine is too much until those jittery feelings begin. The amount of caffeine consumed, the time frame, and the body composition of the person consuming the caffeine all play a part. It also depends on what you are considering too much. &#;It depends on whether you are looking at adverse effects, moderate toxicity or fatal outcomes,&#; said Crouch. &#;Dosing for fatigue is mg every hours &#; and anything that exceeds that is likely to be problematic.&#;

In the most severe cases of caffeine toxicity, the heart and nervous system can be impacted. The South Carolina teen whose death is linked to caffeine went into cardiac arrest. &#;As a stimulant, caffeine increases heart rate as well as causes disturbances in the rhythm of the heart.&#; It can also lower blood pressure in high doses,&#; said Crouch. &#;It also stimulates the central nervous system &#; that&#;s the jittery feeling &#; which can lead to agitation and ultimately can cause delirium and seizures.&#;

In these severe cases, measures can be taken to try to reduce the impacts &#; but there is nothing that can be done to reverse the caffeine toxicity. Unfortunately that only happens as the body metabolizes the caffeine and pushes it out of the body through waste products. &#;Serious toxicity we use supportive measures &#; means to lower heart rate if necessary; means to support blood pressure and anticonvulsants if someone seizes,&#; said Crouch. &#;To keep them out of danger until the caffeine leaves their system.&#;

The best way to avoid potential caffeine complications is to watch your intake. If you think you have had too much, you probably have. And remember, if you are fatigued your body probably needs rest &#; not another cup of coffee.&#;

Is Caffeine Safe, Protective For Patients With AFib, Arrhythmias?

Some caffeinated beverages ─ such as coffee and tea ─ may be safe and may reduce the frequency of arrhythmias, according to a state-of-the-art-review published April 16 in JACC: Clinical Electrophysiology.

Aleksandr Voskoboinik, MBBS, et al., analyzed multiple population-based studies to determine an association between caffeine intake and its effects on atrial and ventricular arrhythmias. The studies consistently showed a decrease in atrial fibrillation (AFib) with an increase in caffeine ingestion, with one meta-analysis of , participants showing AFib frequency decreasing by 6 percent in regular coffee drinkers, and a further analysis of , patients showing a 13 percent risk reduction. 

The authors found that caffeine “does not appear to increase the likelihood of ventricular arrhythmia.” In addition, caffeine doses up to mg daily (approximately six cups of coffee) did not increase the severity or rate of ventricular arrhythmias. A randomized study of post-MI patients who received an average of mg/day resulted in improved heart rate and no significant arrhythmias. Only two studies showed an increased risk for ventricular arrhythmias, in which patients ingested at least 10 cups and nine cups per day, respectively. According to the authors, energy drinks should be avoided by patients with pre-existing heart conditions. Three quarters of patients with pre-existing heart conditions who consumed two or more energy drinks per day reported palpitations within 24 hours.

Both large population studies and randomized control trials suggest caffeine intake of up to mg/day may be safe for arrhythmic patients. However, there may be individual differences in susceptibility to the effects of caffeine on the factors which trigger arrhythmias in some, and up to 25 percent of patients report coffee as an AFib trigger. Patients with a clear temporal association between coffee intake and documented AFib episodes should accordingly be counseled to abstain. Future research looking at the relationship between heart rhythm patients and the impact of caffeine abstinence may be useful to further clarify this topic.

“Caffeinated beverages such as coffee and tea may have long term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,” the authors conclude. “In numerous population-based studies, patients who regularly consume coffee and tea at moderate levels have a lower lifetime risk of developing heart rhythm problems and possibly improved survival.”

Is Caffeine Good or Bad for You?

Are you a regular coffee drinker? Do you sometimes worry that caffeine might be bad for your health? Well, there’s no need to feel guilty about your little coffee habit.  In fact, caffeine has been found to have a lot of positive health benefits and, despite what you may have heard, relatively few drawbacks.

Positive effects of caffeine

People who drink coffee every day have a significantly lower risk of diabetes, Parkinson’s, colon cancer, gallstones, and Alzheimer’s disease. Now, that may not all be due to caffeine. Coffee contains a lot of volatile compounds and antioxidants that may have beneficial effects by themselves, or in combination with caffeine.

For example, drinking tea doesn’t seem to reduce your risk of diabetes, even though tea contains caffeine. On the other hand, people who drink decaffeinated coffee do have a reduced risk, but decaf only seems to work about half as well as caffeinated coffee.

It’s definitely the caffeine that protects against Parkinson’s and Alzheimer’s, though. Not only does caffeine stimulate the brain and central nervous system, but it appears to protect it as well. Caffeine doesn’t make you any smarter but it does makes you more alert and boosts your ability to concentrate, which can make you a better test taker or a better driver.

The benefits of caffeine start kicking in when you consume a cup of coffee or a couple of cups of black tea every day. The positive effects really start piling up when you drink three or four cups of coffee a day or the equivalent. People who drink seven or eight cups a day may get even a little more benefit in terms of neuroprotection, but also have a higher risk of ill effects, such as jitters, agitation, or sleep disruption.

Does caffeine cause or treat headaches?

Caffeine can also relieve headaches. In fact, the popular headache medicine Excedrin contains as much caffeine as a big cup of coffee.  Headaches, especially tension-type headaches, are often accompanied by increased blood flow to the brain. Ths puts pressure on the nerves and causes pain. Caffeine is a vasoconstrictor, meaning that it constricts blood vessels, and this can relieve headache pain. In fact, adding caffeine to a pain reliever like Tylenol can increase the effectiveness by up to 40%. 

If you drink coffee, tea, or other caffeinated beverages regularly, stopping suddenly can also bring on a headache. In fact, it's hypothesized that caffeine withdrawal may contribute to post-operative pain -- because patients typically skip their regular morning cup on the day of surgery. And one study even found that adding a bit of caffeine to the IV liquid for patients recovering from surgery made them quite a bit more comfortable! It can also help people shake off the effects of anesthesia more quickly.

Does caffeine make you a better athlete?

Caffeine also enhances athletic performance. In fact, up until recently, caffeine was considered a performance-enhancing drug by the International Olympic Committee and athletes had to keep their intake of caffeinated beverages fairly low to pass their drug screens. Unlike most performance-enhancing drugs, you can safely try this one at home. Have a cup or two of coffee one hour before your workout and you may be able to go a bit faster, stronger, and longer. This effect may be enhanced if you abstain from coffee for a week or two.

Brock Armstrong of the Get-Fit Guy podcast recently dedicated an episode to using caffeine to enhance your athletic performance.

Myths about caffeine

Many of the negative things you’ve heard about caffeine are actually myths, several of which I’ve debunked in previous shows. It’s a myth, for example, that caffeine weakens your bones, as I explained in my episode on nutrition for healthy bones.

It's also a myth that caffeine consumption is liked to fibrocystic changes, or benign lumps, in the breast. Trial after trial has found no connection between caffeine or coffee consumption and breast lumps or fibrocystic breast disease.  Women who suffer from breast pain and tenderness are often counseled to give up caffeine. And one small study found that 61% of women who cut out (or cut down on) caffeine had improvement of their symptoms. However, this study included no control group. And other research has found that breast pain tends to resolve on its own after a few months. So it's impossible to say whether avoiding caffeine was responsible for the reduction of breast pain.  

And, as I explained in the dehydration myth episode, caffeinated beverages are not dehydrating. Caffeine is a diuretic, meaning that it makes you pee more. But the fluids in coffee and tea more than replace any fluids that you lose due to the diuretic effect. Not only that, but if you drink coffee regularly, it loses it's diuretic effects.

Keep in mind, though, that caffeine pills don’t contain any fluids and, therefore, can be dehydrating.

Finally, you might have heard that caffeine or coffee is bad for your heart. Some studies have found that drinking unfiltered coffee—such as French press or percolated coffee—elevates cholesterol. It appears to be volatile oils in the coffee rather than caffeine that affect cholesterol, and only in men. But coffee drinkers are no more likely to develop heart disease.

Coffee can also cause a temporary increase in your blood pressure but this is not thought to be a concern.  And although caffeinated coffee can also temporarily increase your heart rate a bit, it does not cause irregular heartbeat. In fact, an as yet unpublished study presented at the meeting of the Heart Rhythm Society found that coffee consumption is associated with a lower risk of arrythmias.

Negative effects of caffeine

There are some legitimate downsides of caffeine but they are relatively minor. Some people find that caffeines make them jittery, anxious, or disrupts their sleep. How many cups of coffee it takes to make your hair stand on end, or how late in the day you can drink a cup of coffee without staring at the ceiling all night, are subject to a high degree of individual variation.

People who are very sensitive to stimulants are usually better off avoiding caffeine altogether.  For everyone else, moderate consumption of caffeine appears to have a lot of benefits and limited disadvantages. The alert listener will have noted that I have once again invoked the “M” word: Moderation. Here are your parameters for moderate caffeine consumption:

How much caffeine is too much? 

National health advisory committees in The U.S., Canada, and Europe agree that mg of caffeine per day is perfectly safe for most healthy people. That's the amount you'd get in cups of brewed coffee. (Some energy drinks have up to mg per can.) 

Large amounts of caffeine could negatively affect the growth and development of babies in the womb. Women who are pregnant, planning to become pregnant, or breastfeeding are advised to limit their intake to mg per day or less.

Under normal circumstances, it takes about 5 hours for half of the caffeine you consume to be cleared from your system. Because caffeine can negatively affect sleep quality, you're well advised to avoid drinking caffeinated beverages with 5 to 8 hours of bedtime.

There's really not a lot of data on safe amounts of caffeine for kids or adolescents, which is a concern given the popularity of high-caffeine energy drinks. Some agencies have recommended that kids keep their caffeine intake well under mg per day, which would be the amount in two cans of caffeinated soda. Other experts feel that even that might be unwise. 

What is caffeine found in?

Coffee is the primary source of caffeine in the American diet. (Interestingly, it's also the primary source of antioxidants--by a large margin!)  But varying amounts of caffeine are also found in black and green tea, soda, energy drinks, chocolate, as well as some over-the-counter pain relievers and dietary supplements.  

This infographic, created by mynewextsetup.us, shows the amount of caffeine in many popular beverages.
