Is it true that "Caffeine is a stimulant that enhances alertness and reduces feelings of fatigue. It works by blocking adenosine receptors in the brain. Adenosine is a neurotransmitter that builds up in your brain the longer you're awake and promotes sleepiness. When caffeine blocks the receptors, your brain doesn’t register the adenosine, leading to increased alertness and feeling less of a need to sleep" as mentioned in the episode Dr. Matt Walker: How to Structure Your Sleep, Use Naps & Time Caffeine | Huberman Lab Guest Series?
