Caffeine is a central nervous system stimulant that reduces fatigue and drowsiness. At normal doses, caffeine has variable effects on learning and memory, but it generally improves reaction time, wakefulness, concentration, and motor coordination.
Caffeine is chemically similar to adenosine, a type of sugar that plays a central role in providing energy to your body's cells. Adenosine also plays a role in the transmission of nerve signals. When adenosine attaches itself to neural receptors in your brain, you begin to feel lethargic and sleepy.
