Daylight helps stabilize the sleep-wake cycle.

Restful sleep doesn't just mean sleeping as long as possible. What matters most is that your body and mind can use the night to recharge.
While we sleep, we go through various sleep stages. Deep sleep is important for physical recovery, and REM sleep plays a role in, among other things, information processing and memory.
Stress is a part of life. In the short term, it can help us stay alert, perform well, and be ready to take action. Stress becomes a problem when the pressure persists and we don't get enough rest.
Waking up briefly several times is normal. It becomes a problem if you regularly lie awake for long periods or wake up exhausted in the morning.
When your body is tired but your mind won't shut off: Trouble falling asleep is often caused by stress, overthinking, irregular sleep schedules, caffeine, screen light, or the lack of an evening routine.
