Generally speaking, a healthy sleep should have the following characteristics:
Adequate: Both the quality of sleep and the time of sleep need to be adequate. Although everyone's sleep needs are different, the average adult needs 7-9 hours of sleep.
Regularity: Maintaining a stable sleep pattern helps to promote the adaptability of the body to sleep and improve the quality of sleep. It is recommended to keep a fixed time for sleeping and getting up, and try to avoid staying up late and frequently destroying sleep patterns.
Depth: Sleep depth is also one of the important indicators of healthy sleep, among which deep sleep and rapid eye movement (REM) sleep are the two most important sleep states. Deep sleep helps to restore physical strength and strengthen memory, while rapid eye movement sleep helps to release stress and balance emotions.
Comfort: The sleeping environment needs comfort, including temperature, humidity, light and noise. Reducing noise and irritating light is very important to improve sleep quality.
