How to sleep is healthy? The best sleep time for children 10 hour and adults 7 hours. If you sleep eight hours a day, you will spend one third of your life in sleep.

Sleep time: Sleep time usually lasts 7 to 8 hours, but it is not necessary, depending on individual differences.

They should get effective sleep through various treatments, but prolonging sleep time is harmful to their health.
Because everyone's physiological rhythm is different, the arrangement of going to bed in the morning and evening also varies from person to person! In fact, different circadian rhythms cause two kinds of sleeping situations, namely "night owl" and "lark". Conforming to this physiological rhythm is conducive to improving work efficiency and quality of life, and vice versa.
Sleep environment: Sleep quality is closely related to sleep environment. At the temperature of 15 to 24 degrees Celsius, you can have a good sleep. Moving your eyes means dreaming, and not moving your eyes means deep sleep, but your body temperature will drop significantly.
