Healthy sleep knowledge

People are very familiar with sleep. Sleep is the best way to rest. Only with sufficient sleep can we have enough energy and complete our work better. So how much do people know about healthy sleep? Sleep is divided into deep sleep and light sleep. If six hours of deep sleep are enough, no matter how long the light sleep time is, you will not get a good rest. Let us take a closer look at how to sleep healthily.

How to sleep healthily. The best sleep time for people is: 10 hours for children and 7 hours for adults. If we calculate on eight hours of sleep a day, one third of a person's life is spent sleeping. The quality of sleep is closely related to a person's mental and physical health. There are four elements of sleep, which have a great impact on the quality of sleep.

Sleep time: Sleep time should generally be maintained at 7 to 8 hours, but it is not necessary and should depend on individual differences. People who fall asleep quickly and sleep deeply, and generally have few dreams or few dreams, can fully restore their energy after sleeping for 6 hours. People who fall asleep slowly, have more shallow sleep, and often have many dreams and nightmares, will still find it difficult to feel refreshed even after sleeping for 10 hours. They should undergo various treatments to get effective sleep, as prolonging the sleep time is harmful to the body.

In winter, the smoke left by smoking after closing the doors and windows, as well as the leakage of incompletely burned gas, can also make people unable to sleep. People who live near sources of high-frequency ionizing electromagnetic radiation and suffer from long-term poor sleep rather than personal illness are advised to move to a distant place.

Since everyone has a different physiological rhythm, the arrangement of sleep time should vary from person to person! In fact, different physiological rhythms lead to two types of sleep, namely "night owls" and "larks".

Conforming to this physiological rhythm will help improve work efficiency and quality of life, otherwise it will be detrimental to health. Sleeping environment The quality of sleep is closely related to the sleeping environment. A good sleep can be achieved in a temperature between 15 and 24 degrees.

Eye movement indicates dreaming, while no eye movement indicates deep sleep but the body temperature will drop significantly.

How do we distinguish between good and bad sleep?

The time of entering deep sleep is less than 30 minutes, the deep sleep ratio is more than 41.4% about 3 hours and 18 minutes, the light sleep ratio is less than 36.4%, and the dreaming ratio is 21.6%. The apnea index of less than 5 indicates different fatal diseases. The above is a study by Harvard Medical School.
