Caffeine is a natural stimulant that is found in a variety of plant-based foods and beverages, including coffee, tea, chocolate, and some soft drinks. It is a central nervous system stimulant that can increase alertness and reduce fatigue. It is mainly used as a recreational cognitive enhancer and widely used in certain professions. It is also used by athletes before doing events to give a boost of energy and focus.

How does caffeine work?

Caffeine works by blocking adenosine, a neurotransmitter that promotes sleep and suppresses arousal in the brain. Adenosine is produced by the body as a natural byproduct of energy metabolism, and its levels increase throughout the day, promoting drowsiness and a desire to sleep at night.

When caffeine is consumed, it enters the bloodstream and travels to the brain, where it binds to the adenosine receptors on the surface of brain cells. By binding to these receptors, caffeine blocks the action of adenosine, which prevents it from promoting sleep and suppresses arousal. This results in increased alertness, improved focus, and reduced fatigue.
