Caffeine is a bitter, white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants, as well as enhancing the reward memory of pollinators. It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. Other sources include yerba maté, guarana berries, guayusa, and the yaupon holly. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. It is the world's most widely consumed psychoactive drug, but unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world. Beverages containing caffeine, such as coffee, tea, soft drinks, and energy drinks, enjoy great popularity. In North America, 90% of adults consume caffeine daily. Part of the reason caffeine is classified by the Food and Drug Administration as generally recognized as safe is that toxic doses are much higher than typically used doses. Ordinary consumption has low health risks, even when carried on for years – there may be a modest protective effect against some diseases, including Parkinson's disease, heart disease, and certain types of cancer. Some people experience sleep disruption if they consume caffeine, especially during the evening hours, but others show little disturbance and the effect of caffeine on sleep is highly variable. LESS
Americans don't sleep enough: according to the CDC, 35 percent of adults report they get less than the recommended seven to eight hours of sleep each night. Jawbone today is launching an app that tries to tackle one of the biggest reasons we don't sleep — caffeine. Up Coffee is an app that lets you track how much caffeine you consume in coffee, soda, and other foods, and shows you how it will affect your sleep.
