Sleep-wake cycles, like neuronal firing and heartbeats, require periods of activity followed by periods of rest or refractory phases.

“Same thing for like the way neurons work. Boom action potential, refractory phase. You need to have that period of science, right? Boom action potential and and refractory. Same thing with sleepwake cycles. You need to get awake. Your body temperature rises. Cortisol spikes up. You, you know, you're aware of the world. You're exposed to stressors. Uh if there's not enough stressors, challenges slash meaningful things in your life. You get bored and you want to die. So you need that. But then you need to kind of let go and and sleep, right? So sleepwake cycle, same thing.”
