Can you rely on Wei Zi?

The study pressure is great. In fact, it is ok to sleep for five hours. The key is the quality of sleep, so that the body is really in a sub-health state, and the resistance is easy to decline, but there is no way. I can't sleep if I want to sleep more. Eat more foods rich in protein and cellulose, eat more fruits, and the air conditioning temperature should not be too low at night. If you don't drink ice water during your period, you shouldn't catch a cold. I wish you good health!
