Boosts energy levels

Many people would take a cup of coffee to give them that extra boost of energy and alertness for the day after studying all night or having to get up early for a meeting. Caffeine, a central nervous system stimulant found in coffee, is well known for its ability to fight fatigue and boost energy.

This is because coffee boosts levels of other neurotransmitters in your brain that control your energy levels, such as dopamine, by blocking the receptors of a neurotransmitter called adenosine. In a small study, participants' subjective levels of fatigue were dramatically lowered while the time it took them to get exhaustion during a cycling workout increased by 12%. Similar results were reported by another research, which found that caffeine consumption before and during a round of golf enhanced performance, boosted subjective energy levels, and decreased feelings of fatigue.
