You can use some tips to promote sleep.

1. Drinking a cup of hot milk half an hour before going to bed helps you sleep. Because the nutrition contained in milk can balance metabolism and promote sleep.

Second, you can go for a walk in the corridor or outdoors before going to bed to relax yourself. Soaking your feet with hot water before going to bed will also promote sleep.

Third, after lying in bed, you can press the scalp with your fingers, which can promote blood circulation in the brain, thus relieving brain fatigue and helping sleep.
