Caffeine

Caffeine is a natural stimulant that can be found in tea, coffee, and cacao plants. When you consume caffeine, it has a stimulating effect on your brain and nervous system, helping you feel more alert and awake. It works by attaching to certain receptors in your brain without actually activating them. This prevents a substance called adenosine from making you feel tired. In simple terms, caffeine blocks tiredness signals in your brain, helping you stay awake and feel less fatigued.

Caffeine has been associated with several potential health benefits, although not all of them have been conclusively proven through research.
