caffeine and performance

Caffeine is a natural stimulant that temporarily boosts alertness by blocking dopamine and adenosine receptors in the brain, reducing fatigue and enhancing focus. In terms of performance, moderate caffeine intake can improve physical endurance, reaction times, and mental alertness, making it popular among athletes and professionals. However, the effects vary among individuals and excessive consumption may cause jitters, insomnia, or decreased performance. Overall, caffeine can be a useful aid for enhancing alertness and performance when used responsibly, but it’s important to consider individual tolerance and timing.
