Caffeine

Caffeine is a metabolic stimulant used both recreationally and medically. The substance works to reduce physical fatigue and help to restore mental alertness. Caffeine stimulates the central nervous system resulting in increased alertness and wakefulness, faster and clearer flow of thought, increased focus, and better general body coordination.

Consumption of caffeine is not a substitute for sleep. The body needs to have its rest and although caffeine can reduce drowsiness and feeling of being tired, a proper nights rest is still an essential part of good health practices.

Humans have consumed caffeine since the Stone Age. Early peoples found that chewing the seeds, bark, or leaves of certain plants had the effects of easing fatigue, stimulating awareness, and elevating mood. It is estimated that over 90% of North America adults consume some form of Caffeine everyday.
