The reason why people yawn all day long, why do people yawn?

Stretch your waist and take a deep breath to tilt your head back as much as possible, stretch your arms back, increase the blood flowing into your head, and make your brain more fully nutrient-rich; It can also make the waist move, so that the movement of stretching and contracting, can make the lumbar muscles gradually develop and become stronger and more powerful; And maintain the correct position of the spine to prevent forward bending to form a hunchback, which has a certain effect on the bodybuilding of the body.

Therefore, it is said that "stretching is not lazy", it is not limited by time and place, and this beneficial activity can be completed when chatting, walking, reading, and waiting for the bus.

Many people believe that yawning is the best thing to do, and it feels like a sign of lack of energy. In fact, yawning is the same as burping and sneezing, which is a natural physiological response of human beings, and not only should not be "held back", but should also be played freely for the benefit of health.

Yawning and letting go of beating is good for your health.

Yawning is a response signal of nervous fatigue, indicating that excitement is about to reach or has reached a threshold, and should be turned to inhibition and rest, otherwise the mind will be in a trance, and in the long run, you may even get neurasthenia, which will seriously affect your health.

Yawning is like exercising, taking deep breaths, increasing lung capacity and oxygen supply for physiological activities, expelling exhaust gases, and accelerating metabolism, which is a Western medical explanation that many people understand.

In fact, from the perspective of traditional qigong and health preservation in China, yawning is a typical qigong method: natural relaxation (yawning is generally unconscious, however, people with qigong literacy can artificially guide their yawning with their thoughts and recover fatigue) Qi Shen Dantian, breathing evenly and deeply, and the opening and closing of the upper and lower jaws are just like a winch. When we open our mouths to yawn, there is a sense of urgency in our chests and on the top of our heads.

After closing the mouth, I feel a sense of relaxation, which is the adjustment function of the qi machine.

Sleeping too much or too little can happen to you! ～

I suggest you go to the doctor anyway!

Of course, it's the biological clock.

The first reason is: yawning is a manifestation of hypoxia in the body, especially cerebral hypoxia, which can be seen in low blood pressure, anemia, cerebral insufficiency, cardiovascular and cerebrovascular diseases. Pay attention to rest, don't stay up late, pay attention to diet and nutrition, if there is low blood pressure, anemia and other diseases, it should be timely**.

The second reason is that a healthy person will not be hypoxic in a normal environment, so there is no need for supplemental oxygen; Conversely, a person who is truly deprived of oxygen will experience chest tightness, difficulty breathing, dry lips, etc., and on the contrary, he will not yawn. Yawning is the result of a state of relaxation in the body of the mentally and limb-smiling mimics, and is a manifestation of the body's adjustment to tiredness, rather than a lack of oxygen.

The third reason is that due to the long-term tension of the brain nerve activity, resulting in the dysfunction of brain excitability and inhibition, a group of neurological dysfunctions characterized by mental excitability, brain emotional instability and other symptoms, you can relax your mood, improve the surrounding living environment, or use traditional Chinese medicine to regulate.

Why do people yawn? Let's do it today

Yawning is a very normal physiological phenomenon in the human body, and this phenomenon not only occurs in humans themselves, other animals also yawn, and when we yawn, it often occurs when we just wake up or want to sleepSo why does yawning happen?

Now, according to the relevant theories, there are three main aspects.

First, most people think that yawning is actually related to people's own interests, the human body often yawns when they feel bored, is it always like this, there will always be some boredom when they feel bored, so it is likely to want to sleep caused by yawning.

And this kind of explanation, in fact, according to more professional terms, is because the human body's sense of interest is often associated with the activity of the lower view of the yawning center, and this situation also depends on the different environmental conditions, and many times yawning is contagious between people.

As for the second one, there are still many people who think that the yawning is caused by a lack of oxygenIn fact, in the mother's womb, the fetus will also yawn, and it is also because of these reasons, many people think that it is because the fetal lungs cannot be ventilated in the mother's womb, and the mother contains a lot of carbon dioxide but is seriously lacking in oxygen, so the number of yawning will increase, and everyone yawns in normal times, but also to be able to inhale more oxygen, so yawning is a physiological relief of hypoxia.

The third explanation is that it is caused by the drop in blood temperature in the face after the body inhales cold airWhen the temperature of the tired brain rises, it can cool the brain by yawning and play a balancing role.

This is the explanation of the three reasons why yawning is recognized by more people. Now, the clear question is that yawning is a physiological phenomenon, and what it is ultimately related to has not been clearly proven by more research, and the funny thing is that you find that yawning is contagious!

Because people yawn when they are tired, and this is also a normal physiological reaction, and this is also related to our physical reasons, so we must look at it rationally.

People yawn when they are sleepy, which is also a nervous response, and it is also because they need to yawn to relieve the numbness of the nerves.

People often yawn because of the lack of oxygen to the brain!

Good luck!

1。Sleepy 2. Lack of energy.

3。Keep the air pressure in your ears balanced.

4。Just relax. 5。You see someone yawning, so you do.

In general, low blood oxygen levels are caused by lack of sleep. If it's not sleep deprivation, it's a physical health problem, which may be a problem with blood pressure, blood sugar or cervical spine.

Frequent yawning is actually related to the concentration of oxygen in the body's blood. When people are sleepy, they are actually in a resting state, the time is relatively long, the blood circulation is relatively slow, the oxygen in the blood is consumed, but it is not replenished in time, the concentration of oxygen in the blood is relatively low, and the brain shows a mild hypoxia state. When blood flows through the brainstem of the brain, nerve cells in the brainstem that sense the concentration of oxygen in the blood sense it and give nerve instructions to speed up breathing to provide more oxygen.

So yawning a lot is actually the process of taking a deep breath.

Frequent yawning, that is, the brain is often deprived of oxygen, at this time, it is necessary to check blood pressure, blood sugar, and if necessary, check the condition of the cervical spine to prevent cervical spondylosis from compressing the blood vessels and causing hypoxia.

The specific reasons for frequent yawning are as follows:

1. Insufficient blood and oxygen supply to the brain, and continuous yawning, means that the brain has been insufficient oxygen supply for a long time, at this time, blood lipids will rise, resulting in an increase in the excretion of waste products in the blood, which will lead to narrowing of blood vessels and slow blood flow.

2. Frequent yawning, it may be a problem with the cervical spine. The cervical spine is the connection between the brain and the trunk, if there is a problem with the cervical spine, some transmission functions and transport functions will be hindered, and blood transmission will be hindered, which will easily lead to cerebral hypoxia and ischemia, which will cause yawning.

3. Frequent yawning may be a cardiovascular problem. The heart is responsible for the supply of blood, but if there is a disease around the heart, the rate of blood supply decreases or is blocked, causing hypoxia and ischemia in the brain.

4. When people overuse the brain, it will lead to the death of a large number of brain cells, and if you can't replenish the energy and vitamins you need in time, the brain will be very tired, so it is easy to yawn.

5. When people are in an oxygen-deficient environment, insufficient oxygen supply will lead to hypoxia in the brain. In addition, yawning can increase blood flow to the brain, which has a cooling effect.

How to deal with frequent yawning?

1. If you yawn occasionally, you can pay proper attention to the rest time and maintain sufficient sleep at night. Usually pay attention to rest when working or studying, and remember to take a nap to avoid imbalance in the body's adjustment.

2. When working indoors, it is best to open the windows frequently, ventilate and keep the indoor air smooth.

3. When working, you should often stretch your waist, don't let the cervical spine hang all the time, and occasionally move to prevent cervical spine lesions.

4. Usually supplement more vitamins, eat more vegetables and fruits, and eat less high-oil, high-salt, spicy, raw and cold foods to reduce the occurrence of hyperlipidemia.

5. Usually go out for a walk, exercise, breathe fresh air, relieve fatigue, can also eliminate depression, and maintain a good attitude.

Always yawning, indicating that the concentration of carbon dioxide in the body is relatively high, a little bit of a desire to sleep, you can do more deep breathing, which can relieve the body of Aihua-like can also avoid the sleepiness of Hache will disappear suddenly, don't believe you try it.

This is a normal physiological reaction! It is not necessarily caused by lack of oxygen, it is often the case when you lack sleep or have poor sleep quality, so don't be nervous. Arrange the work and rest time, adjust it, and this phenomenon, you should go to the hospital for a check-up, and the doctor must be professional.

Yawning is the cause of incomplete blood supply.
