Understanding Caffeine: What It Does and How It Works

Caffeine is a naturally occurring stimulant found in coffee, tea, and other plants. It stimulates the brain and central nervous system by blocking adenosine, a neurotransmitter that promotes sleepiness. Despite popular myths, caffeine itself does not provide energy; instead, it increases alertness and decreases drowsiness. Caffeine has numerous benefits, including protecting the liver, reducing the risk of type 2 diabetes and stroke, and even helping with migraines. While caffeine consumption is generally safe, moderation is important. The optimal level of caffeine varies from person to person due to genetic factors. It is crucial to listen to your body's signals and be aware of any negative effects or dependencies on caffeine.
