Caffeine is a component of many drinks and food and is also used in some medication.
How does caffeine work?
Caffeine works by blocking the adenosine receptors in the brain. Adenosine is a substance that inhibits the activity of the central nervous system and causes tiredness. By blocking the adenosine receptors, caffeine increases the activity of the nervous system and leads to a feeling of vigilance and increased energy.
