If sleep is often disturbed, people will be haggard and look old.
The reason is that it interferes with NREM sleep, resulting in reduced growth hormone secretion, which cannot repair aging skin.
Of course, many other important hormones, not only growth hormone, are secreted during this sleep stage.
Some unknown physiological processes secretly maintain health at night.
Not only that, sleep and the body's immune system are also closely related. During sleep, there are regular changes in immune function, and the content of immunomodulatory substances in the brain changes with the sleep process.
And sleep disorder may cause the immune function of the body abnormal and produce pathological process.
It can be seen that if sleep is abnormal, the body's disease resistance will also be affected.
Too much sleep is an invisible mediator of disease
One study found that excessive sleep was associated with an increased risk of colorectal cancer, especially in patients with snoring or who were overweight.
The study found that people who slept at least nine hours a night had a greater risk of developing the disease than those who slept seven hours.
Another study has shown that sleeping too long or too little can increase the risk of diabetes.
Studies have found that if the sleep time is less than 6 hours, the risk of diabetes is about twice that of normal sleepers (seven or eight hours).
If you sleep for more than eight hours, the risk of diabetes increases by three times.
These studies, though, all point to an increased risk of disease with too much sleep.
In fact, excessive sleep is more likely to be the result of some early pathogenic factors in the occurrence of disease, and for downstream diseases, it is only one station in many pathological links.
Snoring or overweight people who sleep too much have an increased risk of colorectal cancer. But if you simply hit the board on too much sleep, it is not objective.
Because snoring or overweight patients are more likely to have sleep apnea, and when sleep apnea occurs, the quality of sleep is poor, the sleep rhythm is disturbed, and the oxygen supply to the brain is often insufficient during sleep.
These will seriously interfere with the normal neuroendocrine function during sleep, but also affect immune function, laying a hidden danger for the occurrence of physical diseases.
And this low-quality sleep can not meet the normal sleep time needs, so the sleep time will be extended, resulting in too much sleep.
Too much sleep is both a result and a symptom. The upstream causes of excessive sleep should be explored.
The mechanism by which too much sleep increases the risk of diabetes also requires similar consideration, such as whether too much sleep is due to eating too much, which is directly related to the occurrence of diabetes.
In addition to sleeping too much, the study subjects whether there are other "good quiet" performance, such as whether insufficient exercise.
These upstream factors can all contribute to excessive sleep. At this time, too much sleep is still in an intermediate position compared to subsequent diseases, and can only be regarded as an intermediary factor.
The upstream factors of disease occurrence are the ones that really need attention. Such as snoring, overweight, eating too much, these can be summarized as a bad lifestyle.
Therefore, to avoid disease and promote health, it is necessary to establish and maintain a healthy lifestyle, respect the original natural laws of the body, do not crush health, and do not have to over-protect, so as to ensure that the body and mind are in a balanced and harmonious steady state.
