Sleep Drive vs. Arousal

Sleep occurs when sleep drive exceeds psychological arousal. Sleep drive refers to the biological processes that make us feel sleepy, and involves adenosine, melatonin and our circadian rhythm. Arousal refers to everything else that keeps us awake. If your arousal exceeds your sleep drive, then you won’t get to sleep.
