Li Yu, a health expert in the Qing Dynasty, said: "The key to health is to sleep first."

People spend13 of their life in sleep, and the quality of sleep is an important basis for affecting people's health. However, due to the heavy pressure of life and busy work of modern young people, many people suffer from different degrees of sleep disorders.

On the occasion of the May 4th Youth Day, let's discuss: What are the causes of sleep disorders? What can I do to have a healthy sleep?

Causes of sleep disorders

Cause 1: excessive pressure.

There are many reasons for sleep disorders, some of which are due to the influence of external environment, such as strong light, noise, too cold or too hot in the bedroom, which easily leads to sleep disorders; Others are caused by psychological reasons, such as anxiety, irritability or excessive mental stress.

Reason 2: cervical dislocation

Some people's ring teeth and the joints of cervical vertebrae are dislocated, and this dislocation is precisely the cause of insomnia or decreased sleep quality. This dislocation also easily leads to headache and dizziness, which affects the quality of sleep.

Therefore, it is suggested that some people who have long-term sleep disorders but can't find the cause may wish to have a cervical examination.

Reason 3: Enjoy the "pleasure" brought by staying up late.

Many young people are completely occupied by work during the day, and there are not a few who stay up late and work overtime. It seems that only the time after turning off the lights is truly their own.

Chasing drama, shopping, playing games, brushing short videos ... While enjoying the pleasure brought by staying up late, I ignored the "distress" signal sent by my body.

Those countless late-night "carnivals" seem to be self-salvation after a busy life, but in fact they are easy to plant seeds of hidden dangers.

The root of the disease: imbalance of yin and yang

Traditional Chinese medicine believes that the root cause of illness lies in the imbalance of yin and yang.

As the old saying goes, "body is the capital of revolution". Modern young people, especially mental workers, are busy with work during the day and have too much mental stress. They are used to staying up late for a long time at night and miss the opportunity of taking a nap, which affects the normal growth of Yin and Yang, which is not only not conducive to the recovery of physical strength and brain power. In the long run, people will be in a sub-health state, their immunity will decline, and they always want to overdraw their "capital" and earn "interest", which often leads to ruin.

Sleep: the best way to generate yang.

Suffering from sleep disorder for a long time will not only lead to listlessness and inattention, but also easily lead to unstable blood pressure and induce various cardiovascular and cerebrovascular diseases.

In Huangdi Neijing, it has been mentioned that Yang has the function of resisting the invasion of diseases and pathogens. Maintaining yang qi has always been considered as the basis of health preservation and treatment. The process of sleeping is the best way to generate yang in the body. Good sleep can improve physical fitness and make people have a healthy body.

Keep healthy and sleep well at noon.

As the saying goes, there are three magic weapons for health preservation: three colds and two downs, and seven points of fullness. The so-called "two falls" means a good nap in the middle of the day.

The so-called meridian sleep refers to falling asleep at midnight and noon on time. Midnight begins with 1, when Yin and Yang meet and fire and water meet, which is called closing Yin, which is the heaviest time of the day and the best time to sleep. Sleeping before midnight is good for nourishing yin. Noon is from 1 1 13, which is also the time when Yin and Yang meet. At this time, the yang is the most abundant, which is called harmony. At this time, taking a nap is good for nourishing yang.

The main principle of meridian sleep is "sleep at noon, take a nap at noon", that is, you must be prepared for sleep around 22 o'clock in the evening, and it is best to fall asleep before midnight (23 o'clock). For those who have to stay up late, instead of staying up until three or four in the morning, it is better to sleep for a while at noon, because the sleep effect during this time far exceeds other time periods.

You only need to take a nap for 30 minutes at noon, because at this time, the yang is strong, the work efficiency is good, and the nap time is too long, which not only wastes precious time, but also disrupts the body's biological clock and affects night sleep. Even if you can't sleep, close your eyes to help the normal handover of Yin and Yang.

In addition, it should be noted that adults should sleep at least 7 hours a day. At the same time, don't do strenuous exercise before going to bed, and don't let your mood fluctuate greatly. You can sit still, take a walk, watch slow-paced TV programs and listen to soothing music before going to bed. To help your body gradually become quiet.

Youth has never been a "shield of death",

Illness will not be merciful because of youth.

Health is not a proper term for any age group.

It only belongs to those who cherish life and live a healthy life.

Finally, I wish you all the best.

Always young, always healthy.

Happy May 4th Youth Day!
