Why is sunlight so important to your sleep? Researchers say it helps set your “body clock”. When there is less and less sunlight at the close of the day, your body starts to make melatonin（褪黑素）. It makes you feel sleepy. Your body makes the most melatonin at night. During the day, sunlight tells your body to make less melatonin, which keeps you awake.
Researchers suggest（建议）we see 15 minutes of sunlight in the morning. It can help balance（平衡）the melatonin in our body.
