100 Two meta analyses have reported that caffeine consumption is associated with a linear reduction in risk for parkinson's disease. 101 16 Caffeine consumption may be associated with reduced risk of depression, 102 although conflicting results have been reported. 103 Caffeine increases intraocular pressure in those with glaucoma but does not appear to affect normal individuals. 104 overdose Primary symptoms of caffeine intoxication 105 Consumption.5 grams (0.0350.053 oz) per day is associated with a condition known as caffeinism. 106 Caffeinism usually combines caffeine dependency with a wide range of unpleasant symptoms including nervousness, irritability, restlessness, insomnia, headaches, and palpitations after caffeine use. 107 Caffeine overdose can result in a state of central nervous system over-stimulation called caffeine intoxication ( dsm-iv 305.90). 108 This syndrome typically occurs only after ingestion of large amounts of caffeine, well over the amounts found in typical caffeinated beverages and caffeine tablets (e.g., more than 400500 mg at a time). The symptoms of caffeine intoxication are comparable to the symptoms of overdoses of other stimulants : they may include restlessness, fidgeting, anxiety, excitement, insomnia, flushing of the face, increased urination, gastrointestinal disturbance, muscle twitching, a rambling flow of thought and speech, irritability, irregular or rapid.

Sensitization, the process whereby effects become more prominent with use, occurs for positive effects such as feelings of alertness and well being. 92 Tolerance varies for daily, regular caffeine users and high caffeine users. High doses of caffeine (750 to mba 1200 mg/day spread throughout the day) have been shown to produce complete tolerance to some, but not all of the effects of caffeine. Doses as low as 100 mg/day, such as a 6 oz cup of coffee pig or two to three 12 oz servings of caffeinated soft-drink, may continue to cause sleep disruption, among other intolerances. Non-regular caffeine users have the least caffeine tolerance for sleep disruption. 93 Some coffee drinkers develop tolerance to its undesired sleep-disrupting effects, but others apparently do not. 94 Risk of other diseases see also: Coffee Health and pharmacology a protective effect of caffeine against Alzheimer's disease and dementia is possible but the evidence is inconclusive. It may protect people from liver cirrhosis. 98 Caffeine may lessen the severity of acute mountain sickness if taken a few hours prior to attaining a high altitude. 99 One meta analysis has found that caffeine consumption is associated with a reduced risk of type 2 diabetes.

The frequency at which this occurs is self reported at 11, but in lab tests only half of the people who report withdrawal actually experience it, casting doubt on many claims of dependence. 92 Mild physical dependence and withdrawal symptoms may occur upon abstinence, with greater than 100 mg caffeine per day, although these symptoms last no longer than a day. 1 some symptoms associated with psychological dependence may also occur during withdrawal. 5 Caffeine dependence can involve withdrawal symptoms such night as fatigue, headache, irritability, depressed mood, reduced contentedness, inability to concentrate, sleepiness or drowsiness, stomach pain, and joint pain. 1 5 The icd-10 includes a diagnostic model for caffeine dependence, but the dsm-5 does not. 3 89 The apa, which published the dsm-5, acknowledged that there was sufficient evidence in order to create a diagnostic model of caffeine dependence for the dsm-5, but they noted that the clinical significance of this disorder is unclear. 3 The dsm-5 instead lists "caffeine use disorder" in the emerging models section of the manual. 3 Tolerance to the effects of caffeine occurs for caffeine induced elevations in blood pressure and the subjective feelings of nervousness.

81 Some state that certain users can become addicted and therefore unable to decrease use even though they know there are negative health effects. 82 83 Caffeine does not appear to be a reinforcing stimulus, and some degree of aversion may actually occur, with people preferring placebo over caffeine in a study on drug abuse liability published in an nida research monograph. 84 Some state that research does not provide support for biography an underlying biochemical mechanism for caffeine addiction. Other research states it can affect the reward system. 88 "Caffeine addiction" was added to the icdm-9 and icd-10. However, its addition was contested with claims that this diagnostic model of caffeine addiction is not supported by evidence. 1 2 89 The American Psychiatric Association 's dsm-5 does not include the diagnosis of a caffeine addiction but proposes criteria for the disorder for more study. 90 91 Dependence and withdrawal main article: Caffeine dependence withdrawal can cause mild to clinically significant distress or impairment in daily functioning.

71 For some people, discontinuing caffeine use can significantly reduce anxiety. 72 In moderate doses, caffeine has been associated with reduce symptoms of depression and lower suicide risk. 73 Some textbooks state that caffeine is a mild euphoriant, others state that it is not a euphoriant, 77 78 and one states that it is and is not a euphoriant. 79 Caffeine-induced anxiety disorder Caffeine-induced anxiety disorder is a subclass of the dsm-5 diagnosis of substance/medication-induced anxiety disorder. Reinforcement disorders Addiction Whether or not caffeine can result in an addictive disorder depends on how addiction is defined. Compulsive caffeine consumption under any circumstances has not been observed, and caffeine is therefore not generally considered addictive. 80 However, some diagnostic models, such as the icdm-9 and icd-10, include a classification of caffeine addiction under a broader diagnostic model.

53 A systematic review, analyzing the results of observational studies, suggests that women who consume large amounts of caffeine (greater than 300 mg/day) prior to becoming pregnant may have a higher risk of experiencing pregnancy loss. 54 Adverse effects Physical Caffeine can increase blood pressure and cause vasoconstriction. Coffee and caffeine can affect gastrointestinal motility and gastric acid secretion. Caffeine in low doses may cause weak bronchodilation for up to four hours in asthmatics. 61 In postmenopausal women, high caffeine consumption can accelerate bone loss. 62 63 Doses of caffeine equivalent to the amount normally found in standard servings of tea, coffee and carbonated soft drinks appear to have no diuretic action. 64 However, acute ingestion of caffeine in large doses (at least 250300 mg, equivalent to the amount found in 23 cups of coffee or 58 cups of tea) results in a short-term stimulation of urine output in individuals who have been with deprived of caffeine for.

64 This increase is due to both a diuresis (increase in water excretion) and a natriuresis (increase in saline excretion it is mediated via proximal tubular adenosine receptor blockade. 65 The acute increase in urinary output may increase the risk of dehydration. However, chronic users of caffeine develop a tolerance to this effect and experience no increase in urinary output. 66 67 Psychological Minor undesired symptoms from caffeine ingestion not sufficiently severe to warrant a psychiatric diagnosis are common and include mild anxiety, jitteriness, insomnia, increased sleep latency, and reduced coordination. 30 68 Caffeine can have negative effects on anxiety disorders. 69 According to a 2011 literature review, caffeine use is positively associated with anxiety and panic disorders. 70 At high doses, typically greater than 300 mg, caffeine can both cause and worsen anxiety.

47 There is no evidence that coffee stunts a child's growth. 48 For children age 12 and under, health Canada recommends a maximum daily caffeine intake of no more than.5 milligrams per kilogram of body weight. Based on average body weights of children, this translates to the following age-based intake limits: 46 Age range maximum recommended daily caffeine intake 46 45 mg (slightly more than in 12 oz of a typical caffeinated soft drink).5 mg 1012 85 mg (about cup of coffee). However, they suggest that daily caffeine intake for this age group be no more than.5 mg/kg body weight. This is because the maximum adult caffeine dose may not be appropriate for light-weight adolescents or for younger adolescents who are still growing. The daily dose.5 mg/kg body weight would not cause adverse health effects in the majority of adolescent caffeine consumers.


This is a conservative suggestion since older and heavier weight adolescents may be able to consume adult doses of caffeine without suffering adverse effects. 46 Pregnancy and breastfeeding The uk food Standards Agency has recommended that pregnant women should limit their caffeine intake, out of prudence, to less than 200 mg of caffeine a day  the equivalent of two cups of instant coffee, or one and a half to two. 49 The American Congress of Obstetricians and Gynecologists (acog) concluded in 2010 that caffeine consumption is safe up to 200 mg per day in pregnant women. 18 For women who breastfeed, are pregnant, or may become pregnant, health Canada recommends a maximum daily caffeine intake of no more than 300 mg, or a little over two 8 oz (237 mL) cups of coffee. 46 There are conflicting reports in the scientific literature about caffeine use during pregnancy. 50 A 2011 review found that caffeine during pregnancy does not appear to increase the risk of congenital malformations, miscarriage or growth retardation even when consumed in moderate to high amounts. 51 Other reviews, however, concluded that there is some evidence that higher caffeine intake by pregnant women may be associated with a higher risk of giving birth to a low birth weight baby, 52 and may be associated with a higher risk of pregnancy loss.

35 Moderate doses of caffeine (around 5 mg/kg 35 ) can improve father's sprint performance, 36 cycling and running time trial performance, 35 endurance (i.e., it delays the onset of muscle fatigue and central fatigue and cycling power output. 35 Caffeine increases basal metabolic rate in adults. Caffeine improves muscular strength and power, 42 and may enhance muscular endurance. 43 Caffeine also enhances performance on anaerobic tests. 44 Caffeine consumption before constant load exercise is associated with reduced perceived exertion. While this effect is not present during to exhaustion exercise, performance is significantly enhanced. This is congruent with caffeine reducing perceived exertion, because exercise to exhaustion should end at the same point of fatigue. 45 Specific populations Adults For the general population of healthy adults, health Canada advises a daily intake of no more than 400 mg. 46 Children In healthy children, caffeine intake produces effects that are "modest and typically innocuous".

Contents Use medical main article: Caffeine citrate caffeine is used in: Enhancing performance cognitive caffeine is a central nervous system stimulant that reduces fatigue and drowsiness. 10 At normal doses, caffeine has variable effects on learning and memory, but it generally improves reaction time, wakefulness, concentration, and motor coordination. 30 31 The amount of caffeine needed to produce these effects varies from person to person, depending on body size and degree of tolerance. 30 The desired effects arise approximately one hour after consumption, and the desired effects of a moderate dose usually subside after about three or four hours. 7 Caffeine can delay or prevent sleep and improves task performance during sleep deprivation. 32 eso Shift workers who use caffeine make fewer mistakes due to drowsiness. 33 A systematic review and meta-analysis from 2014 found that concurrent caffeine and L-theanine use has synergistic psychoactive effects that promote alertness, attention, and task switching ; 34 these effects are most pronounced during the first hour post-dose. 34 Physical Caffeine is a proven ergogenic aid in humans. 35 Caffeine improves athletic performance in aerobic (especially endurance sports ) and anaerobic conditions.

coffee per day or less. 17 18 Caffeine can produce a mild form of drug dependence associated with withdrawal symptoms such as sleepiness, headache, and irritability  when an individual stops using caffeine after repeated daily intake. 1 3 5 Tolerance to the autonomic effects of increased blood pressure and heart rate, and increased urine output, develops with chronic use (i.e., these symptoms become less pronounced or do not occur following consistent use). 19 Caffeine is classified by the us food and Drug Administration as " generally recognized as safe " (gras). Toxic doses, over 10 grams per day for an adult, are much higher than typical doses of under 500 milligrams per day. A cup of coffee contains 80175 mg of caffeine, depending on what "bean" (seed) is used and how it is prepared (e.g., drip, percolation, or espresso ). Thus it requires roughly 50100 ordinary cups of coffee to reach a lethal dose. However, pure powdered caffeine, which is available as a dietary supplement, can be lethal in tablespoon-sized amounts.

It is found in the seeds, nuts, or leaves of a number of plants native to Africa, east Asia and south America, 11 and helps to protect them against predator insects and to prevent germination of nearby seeds. 12, pdf the most well-known source of caffeine is the coffee bean, a misnomer for the seed of, coffea plants. Beverages containing caffeine are ingested to relieve or prevent drowsiness and to improve performance. To make these drinks, caffeine is extracted by steeping the plant product in water, a process called infusion. Caffeine-containing drinks, such as coffee, tea, and cola, are very popular; as of 2014, 85 of American adults consumed some form of caffeine daily, consuming 164 mg on average. 13 Caffeine can have both positive and negative health effects. It can treat and prevent the premature infant breathing disorders bronchopulmonary dysplasia of prematurity and apnea of prematurity. Caffeine citrate is on the who model List of Essential Medicines. 14 It may confer a modest protective effect against some diseases, 15 including Parkinson's disease.

This article is about the resumes stimulant drug. For other uses, see. Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. 10, it is the world's most widely consumed psychoactive drug. Unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world. There are several known mechanisms of action to explain the effects of caffeine. The most prominent is that it reversibly blocks the action of adenosine on its receptor and consequently prevents the onset of drowsiness induced by adenosine. Caffeine also stimulates certain portions of the autonomic nervous system. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
