Have you ever thought that why do we sleep at night?
The answer is :
Light helps you know when to sleep and when to be awake. When you open your eyes in the morning, sunlight lets your brain know it is time to wake up. As day turns to night, your brain makes a chemical called melatonin that makes you sleepy.
