NEGATIVE EFFECTS OF CAFFIENE

NEGATIVE EFFECTS OF CAFFIENE

Caffeine is a chemical found in coffee, tea, cola, guarana, mate, and other products. It is most commonly used to improve mental alertness, but it has many other uses. Caffeine works by stimulating the central nervous system (CNS), heart, muscles, and the centres that control blood pressure. Caffeine can also raise blood pressure. Studies have shown that it may become habit-forming as it riggers certain brain chemicals similarly to the way cocaine and amphetamines do.caffeine anxiety
