Episode Highlights
Adenosine
explains the role of adenosine in sleep regulation and how it accumulates in the brain and body throughout the day. Adenosine makes us feel sleepy and fatigued, and caffeine works by blocking its receptors, temporarily preventing these effects. However, once caffeine wears off, the accumulated adenosine can cause a crash in energy levels.
Adenosine is an incredibly interesting molecule. It exists in the brain and body. It accumulates with the number of hours that you're awake.
