The study found that many healthy and long-lived elderly people have a common feature, that is, enjoying a healthy sleep. When Mr. Zhang Xueliang, who is over 100 years old, was asked about the way of keeping in good health, he replied, "I don't have any special way of keeping in good health, but I can sleep and I know how to sleep." Although Mr. Zhang Xueliang didn't say anything amazing, he told the true meaning of health preservation, that is, to have enough and high-quality sleep.
Good sleep can eliminate general fatigue, rest the physiological functions such as brain nerve, endocrine, substance metabolism, cardiovascular activity, digestive function and respiratory function, replenish and reserve energy, promote the growth and self-repair of various tissues of the body, enhance immune function and improve resistance to diseases, so good sleep is the best natural tonic in the world!
Scientific research shows that sleep can supplement human energy and enhance human immunity. No matter how tired you are during the day, you can have a good sleep. At the same time, sleep can also protect the brain and improve people's brain power, while people who have poor sleep for a long time will lose their memory and brain operation ability. Moreover, a good sleep is also helpful for the self-repair of our organs. In modern medicine, sleep is often regarded as a means to treat diseases. Good sleep can also delay aging and promote longevity. Therefore, a good sleep is more important to health than anything else.
During sleep, the brain repairs the cells responsible for memory and organizes knowledge and information. Lack of sleep or poor sleep quality will damage the brain function and cognitive ability of teenagers and the elderly. Therefore, it is very important to maintain the quality of sleep. Long-term insomnia makes these cells not get enough rest, which leads to inattention, slow response and memory loss. Good sleep helps to enhance immunity, while long-term insomnia has a negative impact on the immune system, which can accelerate the aging of multiple organs, accelerate functional decline, and trigger a series of diseases.
Why is sleep very important for healthy survival? After a hard day's work, our body needs to supplement the consumed nutrients and remove the accumulated metabolites, and this task is mainly completed during sleep. Through adequate sleep, the functions of various systems, organs and tissues of the human body can be restored or restored, so that we can have enough physical strength and energy to devote ourselves to life and work the next day.
24 hours a day, 8 hours sleep, accounting for 1/3. Sleep is the cleverest and most perfect health care method endowed by nature. If we want to stay healthy, we must sleep and wake alternately to achieve balance. Once this natural balance is broken, resulting in lack of sleep, the body can not fully recover when awake during the day, people will feel listless, extremely tired, poor memory and inattention. In the long run, people will lose the first line of defense against diseases, thus threatening their own survival and health.
Some experts have found that the skin is mainly trimmed at night, and the cell division speed at night is twice that during the day; 1 am is the most vigorous time for skin cells to grow. If we watch TV, play computer and play games all night, the secretion of growth hormone in the body will be greatly reduced. Anyone who gets up at three o'clock in the morning will lose immunity the next day, and the immune cells in the blood that protect the human body will decrease 1/3, thus increasing the risk of cancer. In the long run, the human immune system will be destroyed due to lack of sleep, thus greatly increasing the risk of catching cold, pneumonia and other diseases. Research shows that 550,000 people die suddenly every year in China, of which 38.2% are due to lack of sleep.
To stay healthy and keep the first line of defense against diseases, the method is simple: obey the biological clock and go to bed on time! Working regularly to ensure good health is the best investment for the future.
