Episode 02: Sleep PressureWelcome back to the Matt Walker podcast. Today’s episode looks at the story of sleep pressure - how it works, how you can try to block it or fool it, and why you feel so good after a night of full, peaceful sleep. Matt explains that from the moment you wake up, a chemical called adenosine begins to build up in your body. The longer you’re awake, the more adenosine will build up and the sleepier you will feel. This is called sleep pressure. Once adenosine concentrations peak, usually after about 12-16 hours of being awake, the irresistible urge for slumber takes hold. Sleep then purges the buildup of adenosine in your brain, and you will wake feeling refreshed and ready to face another day.Today, you’ll learn about the dual-action effect of adenosine, how caffeine operates to artificially mute its “sleepiness” signals to the brain, and the ideal length of sleep you need to fully clear the adenosine levels from your body overnight.
