Caffeine facilitates learning in tasks in which information is presented passively; in tasks in which material is learned intentionally, caffeine has no effect. Caffeine facilitates performance in tasks involving working memory to a limited extent, but hinders performance in tasks that heavily depend on this, and caffeine appears to improve memory performance under suboptimal alertness.

Most studies, however, found improvements in reaction time. The ingestion of caffeine does not seem to affect long-term memory. Its indirect action on arousal, mood and concentration contributes in large part to its cognitive enhancing properties.

A single photon emission computed tomography SPECT assessment of brain activation in humans showed that caffeine activates regions involved in the control of vigilance, anxiety, and cardiovascular regulation but did not affect areas involved in reinforcement and reward.

Caffeine is not considered addictive, and in animals it does not trigger metabolic increases or dopamine release in brain areas involved in reinforcement and reward. these earlier data plus the present data reflect that caffeine at doses representing about two cups of coffee in one sitting does not activate the circuit of dependence and reward and especially not the main target area, the nucleus accumbens.

Therefore, caffeine appears to be different from drugs of dependence like cocaine, amphetamine, morphine, and nicotine, and does not fulfil the common criteria or the scientific definitions to be considered an addictive substance. Through these interactions, caffeine is able to directly potentiate dopamine neurotransmission, thereby modulating the rewarding and addicting properties of nervous system stimuli.

Caffeine is a natural stimulant found in coffee, tea, chocolate, and other food and drinks. How Does Caffeine Affect People? In both kids and adults, too much caffeine can cause: jitters and nervousness upset stomach headaches problems with concentration trouble sleeping faster heart rate higher blood pressure Especially in young kids, it doesn't take a lot of caffeine to produce these effects.

What Other Problems Can Happen? Although coffee and tea are the most concentrated sources of caffeine, it is also found in soda, cocoa, energy drinks and several types of medication. For example, an energy shot may contain up to mg of caffeine, while some energy drinks provide as much as a whopping mg per can Importantly, the amount of caffeine you can consume without affecting your sleep will depend on your genetics and other factors.

In addition, caffeine consumed later in the day may interfere with sleep because its effects can take several hours to wear off. Research has shown that while caffeine remains in your system for an average of five hours, the time period may range from one and a half hours to nine hours, depending on the individual One study investigated how the timing of caffeine ingestion affects sleep.

Researchers gave 12 healthy adults mg of caffeine either six hours before bedtime, three hours before bedtime or immediately prior to bedtime. Both the time it took all three groups to fall asleep and the time they spent awake at night increased significantly Caffeine can help you stay awake during the day, but it may negatively impact your sleep quality and quantity.

Cut off your caffeine consumption by the early afternoon to avoid sleeping problems. On the other hand, some studies suggest that caffeinated beverages may worsen gastroesophageal reflux disease GERD in some people.

This seems to be especially true of coffee 23 , 24 , In a small study, when five healthy adults drank caffeinated water, they experienced a relaxation of the muscle that keeps stomach contents from moving up into the throat — the hallmark of GERD Since coffee can have major effects on digestive function, you may want to cut back on the amount you drink or switch to tea if you experience any issues.

Although small to moderate amounts of coffee can improve gut motility, larger dosages may lead to loose stools or GERD. Reducing your coffee intake or switching to tea may be beneficial. Rhabdomyolysis is a very serious condition in which damaged muscle fibers enter the bloodstream, leading to kidney failure and other problems.

Common causes of rhabdomyolysis include trauma, infection, drug abuse, muscle strain and bites from poisonous snakes or insects. In addition, there have been several reports of rhabdomyolysis related to excessive caffeine intake, although this is relatively rare 26 , 27 , 28 , In one case, a woman developed nausea, vomiting and dark urine after drinking 32 ounces 1 liter of coffee containing roughly mg of caffeine.

Fortunately, she recovered after being treated with medication and fluids People may develop rhabdomyolysis, or the breakdown of damaged muscle, after they ingest large amounts of caffeine.

A detailed review suggests that although caffeine triggers certain brain chemicals similarly to the way cocaine and amphetamines do, it does not cause classic addiction the way these drugs do In one study, 16 people who typically consumed high, moderate or no caffeine took part in a word test after going without caffeine overnight.

Only high caffeine users showed a bias for caffeine-related words and had strong caffeine cravings In another study, caffeine users completed questionnaires after going 16 hours without consuming it. Daily users had greater increases in headaches, fatigue and other withdrawal symptoms than non-daily users Going without caffeine for several hours may lead to psychological or physical withdrawal symptoms in those who consume large amounts on a daily basis.

However, it has been shown to raise blood pressure in several studies due to its stimulatory effect on the nervous system 33 , 34 , 35 , Elevated blood pressure is a risk factor for heart attack and stroke because it may damage arteries over time, restricting the flow of blood to your heart and brain.

High caffeine intake has also been shown to raise blood pressure during exercise in healthy people, as well as in those with mildly elevated blood pressure 37 , Therefore, paying attention to the dosage and timing of caffeine is important, especially if you already have high blood pressure.

Caffeine seems to raise blood pressure when consumed at high doses or prior to exercise, as well as in people who rarely consume it. It may also lead to altered heartbeat rhythm, called atrial fibrillation, which has been reported in young people who consumed energy drinks containing extremely high doses of caffeine In one case study, a woman who took a massive dose of caffeine powder and tablets in an attempted suicide developed a very rapid heart rate, kidney failure and other serious health issues Indeed, even some people with heart problems may be able to tolerate large amounts of caffeine without any adverse effects.

In one controlled study, when 51 heart failure patients consumed mg of caffeine per hour for five hours, their heart rates and rhythms remained normal Regardless of the mixed study results, if you notice any changes in your heart rate or rhythm after drinking caffeinated beverages, consider decreasing your intake.

Large doses of caffeine may increase heart rate or rhythm in some people. These effects appear to vary greatly from person to person. If you feel them, consider reducing your intake.

It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, [15] and helps to protect them against herbivores and from competition by preventing the germination of nearby seeds, [16] as well as encouraging consumption by select animals such as honey bees. People may drink beverages containing caffeine to relieve or prevent drowsiness and to improve cognitive performance. To make these drinks, caffeine is extracted by steeping the plant product in water, a process called infusion.

Although ingestion of caffeine can increase blood sugar in the short-term, long-term studies have shown that habitual coffee drinkers have a lower risk of developing type 2 diabetes compared with non-drinkers.

The polyphenols and minerals such as magnesium in coffee may improve the effectiveness of insulin and glucose metabolism in the body. Caffeine is a stimulant affecting the central nervous system that can cause different reactions in people.

In sensitive individuals, it can irritate the stomach, increase anxiety or a jittery feeling, and disrupt sleep. Although many people appreciate the temporary energy boost after drinking an extra cup of coffee, high amounts of caffeine can cause unwanted heart palpitations in some.

Unfiltered coffee, such as French press and Turkish coffees, contains diterpenes, substances that can raise bad LDL cholesterol and triglycerides. Espresso coffee contains moderate amounts of diterpenes. Filtered coffee drip-brewed coffee and instant coffee contain almost no diterpenes as the filtering and processing of these coffee types removes the diterpenes.

Despite these factors, evidence suggests that drinking coffee regularly may lower the risk of heart disease and stroke :.

Naturally occurring polyphenols in both caffeinated and decaffeinated coffee can act as antioxidants to reduce damaging oxidative stress and inflammation of cells.

It may have neurological benefits in some people and act as an antidepressant. However in a few cases of sensitive individuals, higher amounts of caffeine may increase anxiety, restlessness, and insomnia. Suddenly stopping caffeine intake can cause headache, fatigue, anxiety, and low mood for a few days and may persist for up to a week.

There are various proposed actions of caffeine or components in coffee that may prevent the formation of gallstones. The most common type of gallstone is made of cholesterol. Coffee may prevent cholesterol from forming into crystals in the gallbladder.

It may stimulate contractions in the gallbladder and increase the flow of bile so that cholesterol does not collect. A study of 46, men tracked the development of gallstones and their coffee consumption for 10 years.

After adjusting for other factors known to cause gallstones, the study concluded that men who consistently drank coffee were significantly less likely to develop gallstones compared to men who did not.

The bottom line: A large body of evidence suggests that consumption of caffeinated coffee does not increase the risk of cardiovascular diseases and cancers. In fact, consumption of 3 to 5 standard cups of coffee daily has been consistently associated with a reduced risk of several chronic diseases.

Specifically, those who have difficulty controlling their blood pressure may want to moderate their coffee intake. Pregnant women are also advised to aim for less than mg of caffeine daily, the amount in 2 cups of coffee, because caffeine passes through the placenta into the fetus and has been associated with pregnancy loss and low birth weight.

Decaffeinated coffee is a good option if one is sensitive to caffeine, and according to the research summarized above, it offers similar health benefits as caffeinated coffee.

The extra calories, sugar, and saturated fat in a coffee house beverage loaded with whipped cream and flavored syrup might offset any health benefits found in a basic black coffee. Coffee beans are the seeds of a fruit called a coffee cherry. Coffee cherries grow on coffee trees from a genus of plants called Coffea.

There are a wide variety of species of coffee plants, ranging from shrubs to trees. Decaffeinated coffee. This is an option for those who experience unpleasant side effects from caffeine.

The two most common methods used to remove caffeine from coffee is to apply chemical solvents methylene chloride or ethyl acetate or carbon dioxide gas. Both are applied to steamed or soaked beans, which are then allowed to dry. According to U. Both methods may cause some loss of flavor as other naturally occurring chemicals in coffee beans that impart their unique flavor and scent may be destroyed during processing.

However, adding sugar, cream, and milk can quickly bump up the calorie counts. A tablespoon of cream contains 52 calories, and a tablespoon of whole milk contains 9 calories.

However, the real caloric danger occurs in specialty mochas, lattes, or blended ice coffee drinks. These drinks are often super-sized and can contain anywhere from calories, as well as an extremely large amount of sugar.

Cancer Coffee may affect how cancer develops, ranging from the initiation of a cancer cell to its death. Type 2 Diabetes Although ingestion of caffeine can increase blood sugar in the short-term, long-term studies have shown that habitual coffee drinkers have a lower risk of developing type 2 diabetes compared with non-drinkers.

In a meta-analysis of 45, people with type 2 diabetes followed for up to 20 years, an association was found with increasing cups of coffee and a lower risk of developing diabetes.

Caffeinated coffee showed a slightly greater benefit than decaffeinated coffee. Heart health Caffeine is a stimulant affecting the central nervous system that can cause different reactions in people.

The authors found no such association with other caffeinated drinks such as tea and soda. These coffee-specific results suggest that components in coffee other than caffeine may be protective. Heavier coffee intake of 6 or more cups daily was neither associated with a higher nor a lower risk of cardiovascular disease.

Depression Naturally occurring polyphenols in both caffeinated and decaffeinated coffee can act as antioxidants to reduce damaging oxidative stress and inflammation of cells.

to 2 cups of coffee. found a decreasing risk of suicide with increasing coffee consumption. There was no association between decaffeinated coffee and suicide risk, suggesting that caffeine was the key factor, rather than plant compounds in coffee.

There is consistent evidence from epidemiologic studies that higher consumption of caffeine is associated with lower risk of developing PD. The caffeine in coffee has been found in animal and cell studies to protect cells in the brain that produce dopamine.

In that time, after adjusting for known risks of PD, those who drank at least 10 cups of coffee a day had a significantly lower risk of developing the disease than non-drinkers.

Women showed the lowest risk when drinking moderate intakes of cups coffee daily. The authors stated the need for larger studies with longer follow-up periods. Gallstones There are various proposed actions of caffeine or components in coffee that may prevent the formation of gallstones.

Mortality In a large cohort of more than , participants followed for up to 30 years, an association was found between drinking moderate amounts of coffee and lower risk of early death. Both caffeinated and decaffeinated coffee provided benefits.

The authors suggested that bioactive compounds in coffee may be responsible for interfering with disease development by reducing inflammation and insulin resistance. The protective effect was present regardless of a genetic predisposition to either faster or slower caffeine metabolism.

Instant and decaffeinated coffee showed a similar health benefit. What about iced coffee? Caffeine Caffeine is naturally found in the fruit, leaves, and beans of coffee, cacao, and guarana plants.
