Andrew Huberman: Sleep, Exercise & Light for Adenosine Clearance

Can Anything Besides Sleep Clear Adenosine?

Huberman and Walker discuss the effects of various substances and activities on sleep and wakefulness. They explain that while exercise, daylight exposure, and other factors can promote alertness, they don’t necessarily alter adenosine levels directly.

Walker emphasizes that it’s primarily sleep, especially non-REM sleep, that allows the brain to remove adenosine. During deep non-REM sleep, the brain becomes less metabolically active, enabling the natural mechanisms to clear adenosine more effectively.

They also suggest that anesthesia and liminal states, such as non-sleep deep rest, could potentially mimic the adenosine-dissipating effects of sleep by reducing brain activity. However, further research is needed to confirm these hypotheses.
