Mondo Knows Facts
Adenosine builds up in the brain while awake
This breakdown product of cellular energy accumulates and increases the drive to sleep As brain cells burn ATP through the day, adenosine accumulates in the fluid around them. It binds receptors that dampen arousal circuits, creating what researchers call sleep pressure. Levels fall during sleep, partly because the compound is cleared and rebuilt into ATP. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
