Your body runs on circadian rhythms—patterns in biological processes that repeat every day. And those cadences are controlled by an internal clock.
Where is the body's clock? In the part of the brain called the hypothalamus, above where the optic nerves cross, is a group of about 20,000 nerve cells known as the suprachiasmatic nucleus (SCN). Influenced by light, it controls your body’s production of the sleep-inducing hormone melatonin. When light levels are low, like at night, the SCN tells your brain to churn out melatonin, which makes you sleepy.
