Caffeine as a Performance Booster and Health Protector

Caffeine is often consumed to enhance performance, whether it's for studying, working, or taking tests. However, it's important to note that caffeine doesn't actually provide energy; it simply blocks the neurotransmitter adenosine, which makes us feel drowsy. Additionally, caffeine offers various health benefits, such as protecting the liver, reducing the risk of type 2 diabetes, lowering the risk of stroke in women, reducing the risk of Parkinson's disease, and aiding in the treatment of headaches. Despite misconceptions and concerns about caffeine addiction, it is not considered an addictive substance by the US, although some individuals may develop tolerance and withdrawal symptoms when consuming excessive amounts of caffeine.
