With the continuous development of the fast-paced society, many people today have encountered some major or minor problems in sleep. Although sleep is a very normal physiological phenomenon, many people have problems such as lack of sleep or poor sleep quality due to environmental work, diet, family and personal physical conditions.

When a person reaches the stage of middle-aged and elderly people, there will be many changes. One of the characteristics that is most different from young people is that young people do not get enough sleep, while middle-aged and old people can’t sleep even if they want to.

There are two extremes in its sleep situation: one is to get up early and go to bed early, and get up especially early! In addition, if you sleep less, many insomnia symptoms will occur, some of which are more serious and even cannot fall asleep at two or three o'clock at night, and wake up at six or seven in the morning.

Are we all deceived by the "8-hour sleep theory"?

Nowadays, many people think that sleeping for 8 hours a day is enough to meet the needs of the human body, and the sleep time is also different from person to person. In fact, there is no scientific basis to prove that this 8 hours of sleep can meet the needs of people.

The sleep of the human body is often affected by many factors, including the hormone stability in the body, the circulation and transportation function of the blood, and the functioning state of the body's organs. The 8-hour sleep time is only for reference, and there is no uniformity in the specific optimal sleep time for people of different ages.

After 50, what is the best time to sleep?

50-year-old middle-aged men are best to control the sleep time to about 7 hours,

For 50-year-old middle-aged women, it is best to control the sleep time to about 7.5 hours,

And should ensure "quality sleep time" from 10:00 pm to 5:00 am. Because people are easy to reach a deep sleep state at this time, it helps to relieve fatigue.

For children, adolescents and the elderly, their sleep status is also different. Children who are growing and developing can sleep more due to physical reasons.

It is necessary for children aged 4 to 10 to sleep 12 hours a day, go to bed around 8 o'clock every night, and take a nap as much as possible at noon. Older children sleep 10 or even 8 hours.

The elderly should go to bed before 12 o'clock every night, and sleep for 7 hours at night, or even 5.5 hours is enough.

According to data released by the Alzheimer's Association, elderly people who sleep less than 7 hours a night can delay brain aging by 2 years. Long-term sleep of more than 7 hours or insufficient sleep can lead to poor concentration, even Alzheimer's, and increase the risk of premature death.
