Caffeine: How the World’s Favorite Stimulant Powers Our Lives
Caffeine is a potent natural stimulant primarily found in coffee, tea, and various energy drinks, cherished for enhancing alertness and alleviating fatigue. By inhibiting adenosine, it raises neuron activity and neurotransmitter release, boosting energy and focus. However, excessive intake can cause side effects like insomnia and increased heart rate, alongside tolerance and withdrawal symptoms. Understanding personal tolerance and moderating consumption is vital to harness its benefits while minimizing negative impacts on health.
