When it comes to the best sleep time, the first thing you think of is that you must sleep for 8 hours every night. If you don't sleep enough, you may be sleepy. If you sleep too much, you waste time. Many people say that they have slept for 8 hours. Why do they still feel sleepy? In fact, most people are deceived by the eight hour sleep theory.
There is no doubt that the lack of sleep time caused by various reasons will indeed bring harm to human health, such as obesity, mental depression, inability to concentrate, memory decline, etc.
However, sleeping too much will also bring harm to the human body. Some studies show that if you sleep more than 9 hours a day, you will increase the risk of cardiovascular disease.
Is 8 hours the best time for people to sleep
In fact, the human body, as a living organism, needs different hours of sleep. The eight-hour sleep theory cannot cover all people.
For example, Mrs. Thatcher's sleep time is 4~6 hours, far less than 8 hours, but she can still keep energetic every day, while the African, Bolt, said that he needs 10 hours of sleep every day, otherwise he will be listless.
Some people have good sleep quality. Generally, 5-6 hours of deep sleep can reach 8 hours or more of others' sleep. Therefore, it is not necessary to use 8 hours of sleep to measure whether a person has got enough rest, but it is different from person to person according to personal constitution or working and living conditions
What is the best time to sleep after 60
The daily physical activity of the elderly is getting less and less, and they often feel tired and weak. Affected by the increasingly poor secretion of melatonin, the sleep time of the elderly is generally shortened.
For such people, 8 hours is not the best golden sleep time. The advice given by WHO is that people over 60 years old should only have 5-6 hours of sleep every day, which is enough to make their bodies get enough rest.
How to improve sleep quality
The elderly are easily awakened by some small sounds or light when they sleep, and it is very difficult to fall asleep again. It is suggested that the bedroom should be selected. The side away from the downtown area should be selected with a good shading effect. The desk lamp should be selected with a soft light color to avoid sudden glare of strong light when the light is turned on. You can also wear an eye mask when sleeping, so you don't have to worry about being disturbed by the light
Avoid heavy work half an hour before going to bed. Don't go to sleep with problems in your mind. You can listen to light music to help you sleep. At the same time, you should maintain correct sleep posture and relax your whole body. If you have insomnia occasionally, don't worry too much, and don't rely on sleeping pills for a long time.
