The Role of Adenosine in Sleep Quality

What determines how well we sleep and the quality of our wakeful state? Turns out that’s

governed by two forces. The first force is a chemical force. It’s called adenosine.

Adenosine is a molecule in our nervous system and body that builds up the longer we are awake.

So if you've just slept for eight or nine or ten really deep restful hours, adenosine is going

to be very low in your brain and body. If, however, you’ve been awake

for 10, 15, or more hours, adenosine levels are going to be

much higher. Adenosine creates a sort of sleep drive or a sleep hunger.
