Learn to Walk Out of Eight Sleep Misconceptions
Misconception One: The more sleep, the more beneficial to health
Currently, some office workers like to "catch up on sleep" on weekends, but they often find later that their mental state on weekends is not as good as on weekdays. Experts believe that the length of sleep time has little to do with healthy sleep. Everyone's sleep time is different, with great individual differences. Quality is more important than time, and the most important thing is to maintain regularity in life.
Misconception Two: Dreaming at night means you haven't rested well
Dreaming is a common physiological phenomenon. Every normal person dreams during sleep, about 4 times a night. However, if you feel energetic the next day, you cannot consider that you haven't rested well.
Misconception Three: Alcohol can induce sleep
In real life, many people drink a little alcohol before going to bed, thinking it can help them fall asleep quickly. Experts believe this practice is not advisable. During sleep, harmful substances in alcohol accumulate in the body, poisoning it and damaging the retina, which can reduce the body's adaptability.
Misconception Four: Sleep can be stored and pre-spent
If what is pre-spent is an extended period of wakefulness, it is equivalent to overdrawing on life. Subsequent sleep compensation can only alleviate subsequent fatigue, but it cannot repay the prematurely overdrafted mental and physical energy, nor can it repair the damage to the body caused by it.
Misconception Five: Sleep disorders are not a disease
It is understood that 8% of people experience sleep disorders of varying degrees in their lifetime. Insomnia can be eliminated, and poor sleep is not the same as neurasthenia. For a small number of people with sleep disorders, it may be a manifestation of certain diseases that have not yet appeared or have already appeared.
Misconception Six: No need for a nap
Napping helps to coordinate the biological clock and the 24-hour cycle. However, the nap should not be too long, with 15 minutes being appropriate. Studies have shown that napping can prevent premature aging and reduce the incidence of cardiovascular diseases by 30%. However, napping is not suitable for everyone. People who are 20% overweight, have low blood pressure, or suffer from serious circulatory system diseases may often suffer from insufficient blood supply to the brain due to napping, leading to a stroke.
Misconception Seven: Sleeping pills can be taken long-term
The sleep brought about by sleeping pills cannot replace natural sleep. This is because more than 95% of hypnotics shorten deep sleep. Experts point out that so far, no exogenous sleeping pill without side effects has been found, and taking sleeping pills should be under the guidance of a doctor.
Misconception Eight: Physical exercise has only benefits for insomnia
Physical exercise can be used as an adjunctive treatment for insomnia patients, but avoid strenuous exercise before bedtime, otherwise, the brain is easily excited, leading to insomnia. After morning exercise, the elderly should not go back to sleep for a nap.
