According to the calculation of sleeping 8 hours a day, sleep occupies one-third of the time of life, so sleep is a thing that everyone is very concerned about, and it is also the common dream of everyone to sleep peacefully every night.
However, in daily life, some understanding of sleep is actually incorrect, such as thinking that the longer you sleep, the better, but there are still many friends who do not know the truth.
What are the common cognitive misunderstandings of sleep, and don't be misled by these illusions in the future.
1, the longer you sleep, the better
Adults are usually advised to sleep 7 to 9 hours a day, but that doesn't mean the longer you sleep, the better. Because when people sleep, the heartbeat and blood circulation will slow down, and the nutrients and oxygen supplied to the brain will be reduced accordingly.
If you sleep for too long, brain cells do not get an adequate supply of oxygen and nutrients, which will lead to a decrease in nerve excitability, affecting energy and physical strength.
Similarly, the nap time should not be too long, about 30 minutes is almost the same, because once it exceeds 45 minutes, it will enter a deep sleep state, so that it is easy to have a mental trance after waking up.
In addition, a long nap can also easily lead to insomnia at night, and over time, it will disturb the body's biological clock.
2, the elderly do not need to sleep too much
In fact, the elderly, like young people, need the same length of sleep time, and it is best to ensure that they sleep 7 to 9 hours a day. And the elderly that everyone mistakenly believes do not need to sleep too much, just because with the increase of age, the body's sleep patterns have changed, and the elderly are more likely to wake up at midnight and early in the morning, so the sleep time at night is correspondingly shortened.
But in fact, the elderly's demand for sleep is not less than that of young people, it is recommended that the elderly can take a nap during the day to supplement the lack of sleep at night.
3, stay up late can make up for sleep on the weekend
Due to the huge pressure of work and life, many people have been working overtime, resulting in frequent staying up late, and the next day still have to go to work on time, so there is a serious lack of sleep. This type of person often wants to make up for the lack of sleep by sleeping lazily on the weekend. In fact, sleep compensation can only relieve the fatigue of the body, and can not make up for the damage caused to the body by staying up late for a long time.
In addition, sleeping too long on weekends can disrupt sleep patterns, cause insomnia at night, reduce sleep quality, and in the long run, lead to sleep disorders.
4. Snoring means sleeping soundly
Snoring is due to the collapse of the upper respiratory tract while a person is sleeping, resulting in narrowing of the respiratory tract, and when the air flow passes through the narrowed respiratory tract, it will cause vibrations and snoring.
Therefore, snoring during sleep does not mean that you sleep soundly, but reflects the problem of obstructive sleep apnea in the body, which can easily lead to lack of oxygen in the human body.
Therefore, snoring people tend to wake up easily feeling tired or lack of energy. In addition, long-term snoring will also increase the risk of diseases such as hypertension, diabetes, cardiovascular and cerebrovascular diseases. Therefore, friends who are more serious about snoring must be vigilant and recommend going to the hospital for professional diagnosis and treatment.
In daily life, there are some understandings about sleep that are actually incorrect, such as thinking that the longer you sleep, the better, the elderly do not need to sleep too much, staying up late on weekdays can make up for sleep on weekends, snoring indicates that you sleep soundly.
These wrong cognitions will lead to the formation of bad sleep habits, which in turn will affect human health, so to sleep well, we must stay away from these misunderstandings, otherwise the body will lose its temper.
