How to sleep healthy? The optimal amount of sleep for a person is 10 hours for a child and 7 hours for an adult. If you sleep eight hours a day, one-third of a person's life is spent in sleep. The quality of sleep is closely related to one's mental and physical health. There are four elements of sleep that have a great impact on the quality of sleep.

Sleep time: sleep time should be maintained generally 7 to 8 hours, but not necessarily forced, depending on individual differences. Sleep fast and sleep deep, generally no dream or less dream, sleep on the 6 hours can be fully rejuvenated; slow to sleep and shallow sleep eyes, often more dreams and nightmares, even if the sleep on the 10 hours, it is still difficult to refreshing, should be through a variety of treatments in order to get an effective sleep, just prolong the sleep time is harmful to the body.

As each person has a different physiological rhythm, in the arrangement of sleep morning and evening to vary from person to person! In fact, different physiological rhythms make sleep appear in two cases, namely "night owl" and "lark". This physiological rhythm is conducive to improving work efficiency and quality of life, and vice versa, is not good for health.

Sleep environment: Sleep is good or bad, and sleep environment is closely related. In a temperature of 15 to 24 degrees Celsius, you can get a peaceful sleep. Eye rotation indicates dreaming, no eye rotation indicates deep sleep but body temperature will drop significantly.
