One study investigated how the timing of caffeine ingestion affects sleep. Researchers gave 12 healthy adults 400 mg of caffeine either six hours before bedtime, three hours before bedtime or immediately prior to bedtime. Caffeine may be synthesized in the lab starting with dimethylurea and malonic acid. [ clarification needed] [200] [201] [205]

Caffeine in coffee and other caffeinated drinks can affect gastrointestinal motility and gastric acid secretion. [86] [87] [88] In postmenopausal women, high caffeine consumption can accelerate bone loss. [89] [90] In fact, evidence shows a 16–18% lower risk of heart disease in men and women who drink between 1–4 cups of coffee daily (providing approximately 100–400 mg of caffeine) ( 29). What about coffee’s other long-term benefits? There is some evidence that its mood-elevating effects can be beneficial over the long term. In a 2016 meta-analysis of observational studies, caffeine consumption was found to decrease the risk of depression, while a Finnish study from 2010 found a similar result with coffee. In the Finnish study, the connection was weaker when other caffeinated drinks were consumed – suggesting that there is something in coffee specifically that can affect mood. One theory is that it’s the antioxidants, as these tend to correlate with reduced stress overall.

Giving up caffeine comfortably

Knowing your caffeine intake is particularly important in childhood and adolescence. There's a reason energy drinks are set to be banned for children in England: younger brains are more sensitive to caffeine. As a rule of thumb, children should consume no more than 3 mg of caffeine a day for every kilo of their body weight. (For a child weighing 40 kg, this would equate to 120 mg - about the same as one strong coffee.) 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, 25). Obviously, if you drink half a pint of milk and two sugars in your latte, it increases the calorie count; is there any way to mitigate that? With a sprinkle of cinnamon, perhaps? “It’s probably not going to have a huge effect on fat-burning,” says Nelson. “There are some studies showing that it may help with glucose metabolism if you give it in a pretty high dose – so if you’re looking at glycemic control, it may be helpful for that. But I wouldn’t count on a little dusting doing much good.” Caffeine's biological half-life– the time required for the body to eliminate one-half of a dose– varies widely among individuals according to factors such as pregnancy, other drugs, liver enzyme function level (needed for caffeine metabolism) and age. In healthy adults, caffeine's half-life is between 3 and 7hours. [8] The half-life is decreased by 30-50% in adult male smokers, approximately doubled in women taking oral contraceptives, and prolonged in the last trimester of pregnancy. [126] In newborns the half-life can be 80hours or more, dropping very rapidly with age, possibly to less than the adult value by age 6 months. [126] The antidepressant fluvoxamine (Luvox) reduces the clearance of caffeine by more than 90%, and increases its elimination half-life more than tenfold; from 4.9hours to 56hours. [187]

For the general population of healthy adults, Health Canada advises a daily intake of no more than 400mg. [72] This limit was found to be safe by a 2017 systematic review on caffeine toxicology.

This causes a relative increase in other signaling molecules, such as dopamine and norepinephrine ( 5, 6).Structure of a typical chemical synapse Caffeine's primary mechanism of action is as an adenosine receptor antagonist in the brain. these terms and conditions in full. If you disagree with any part of these terms and conditions, do Caffeine is used as a primary treatment for apnea of prematurity, [40] but not prevention.

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 ( 40). Xocolatl was introduced to Europe by the Spaniards, and became a popular beverage by 1700. The Spaniards also introduced the cacao tree into the West Indies [252] and the Philippines.

Who needs to cut down on caffeine?

Common causes of rhabdomyolysis include trauma, infection, drug abuse, muscle strain and bites from poisonous snakes or insects. Some analog substances have been created which mimic caffeine's properties with either function or structure or both. Of the latter group are the xanthines DMPX [210] and 8-chlorotheophylline, which is an ingredient in dramamine. Members of a class of nitrogen substituted xanthines are often proposed as potential alternatives to caffeine. [211] [ unreliable source?] Many other xanthine analogues constituting the adenosine receptor antagonist class have also been elucidated. [212] Until recently, the Seventh-day Adventist Church asked for its members to "abstain from caffeinated drinks", but has removed this from baptismal vows (while still recommending abstention as policy). [282] Some from these religions believe that one is not supposed to consume a non-medical, psychoactive substance, or believe that one is not supposed to consume a substance that is addictive. The Church of Jesus Christ of Latter-day Saints has said the following with regard to caffeinated beverages: "... the Church revelation spelling out health practices (Doctrine and Covenants 89) does not mention the use of caffeine. The Church's health guidelines prohibit alcoholic drinks, smoking or chewing of tobacco, and 'hot drinks' – taught by Church leaders to refer specifically to tea and coffee." [283] Grosso G, et al.

Additionally, modest doses have been shown to cause rapid breathing and increase stress levels when consumed in one sitting ( 11, 12).
