Because this time is a time of more metabolism and better internal adjustment, we should cherish this time and don't stay up late. Sleeping at night will go through several stages: deep sleep, dreaming and shallow sleep. In the process of deep sleep, it is completely relaxed and it is difficult to wake up. The first deep sleep stage is reached shortly after falling asleep, so early sleep is more suitable for rest.

An adult's deep sleep only accounts for 15%~20% of his whole sleep time, with an average of 90 minutes. Therefore, women should cherish this time, give their skin enough time and opportunities, recuperate through sleep, and maintain a beautiful face. It is recommended to take a hot bath before going to bed to deeply clean the facial skin. You can also listen to light music to help you sleep. If you have insomnia, it is recommended to drink a glass of warm milk before going to bed.

The function of sleep

Our sleep at night goes through several stages: deep sleep, dreaming and shallow sleep. In the process of deep sleep, we are completely relaxed and it is difficult to wake up. The first stage of deep sleep is achieved shortly after falling asleep, so the rest effect is best when you just fall asleep. The later we go to bed, the shorter the deep sleep time.
