Humans rely on blood to transport nutrients to all organs of the body, even to the end of tissues, and even to every cell. Once the blood can't be transmitted, any tissue and cell will die, especially the brain. As long as the blood supply is slightly insufficient, it will be unbearable immediately.
If the brain is short of energy, the first thing to give up is cognitive functions such as memory and willpower. In the long run, dementia will advance step by step; On the contrary, if the blood circulation is sufficient, including all organs except the brain, it will not decline and you can live a long and healthy life.
Poor posture makes the head prone to lack of oxygen.
Generally speaking, the blood flow of gray matter in the brain will decrease by 60% from 30 to 80 years old. The so-called gray matter refers to the part of the central nervous system in which neurons have cell bodies, as opposed to the part without cell bodies and only nerve axons, which is called white matter. If you don't take care of it early, you don't have to wait until you are 80 years old, you will gradually become a brain with poor blood circulation, and the probability of suffering from dementia will gradually increase.
Hideki Matsubara, a famous Japanese doctor of medicine, pointed out in his book "It is too early to prevent dementia from the age of 40" that if you want to build an oxygen-rich brain, you must pay attention to the blood circulation of the brain, especially the posture, which may affect the chest to inhale enough oxygen. If it is long-term, it may easily become dementia.
Modern people generally have bad posture, either hunched over, sitting or standing. "If the back arch is as round as a turtle shell, the chest will be squeezed and the inhalable oxygen will be reduced. In this way, it will not provide enough oxygen to the brain, and it will become easy to get dementia. " Matsubara Hideki pointed out.
Maintaining a good posture will concentrate a lot of blood in the lower body. When we walk, after one step, the blood flow originally concentrated in the lower body will return to the heart, and the blood will be transported to the whole body, including the brain, through the operation of the heart pump.
Bad posture will also force other parts of the body to bear too much burden, which will make the blood flow poor and hinder the blood circulation of the whole body. In the end, it will easily reduce the cerebral circulation and fall into a state of hypoxia.
Abdominal breathing increases oxygen intake
In addition to correct posture, deep breathing every day can also increase oxygen intake. In fact, both western medicine and Chinese medicine emphasize the idea of keeping in good health through breathing. Including yoga, which we often hear, breathing through the nose and exhaling through the mouth, or the so-called "breathing method" of China Qigong, which makes breathing slow, long, even and deep and sends the breath to the abdomen.
As for the way to take a deep breath, you can start with inhaling. The key point is to inhale a lot of air through repeated deep breaths, so that the body can get enough oxygen. However, Futong-Qiu, director of the Rehabilitation Department of Dongyuan General Hospital, reminded that although repeated deep breathing can increase the exchange of oxygen, it is not enough, because repeated deep breathing may also cause excessive breathing and rapid contraction of blood vessels, which is not good for health.
Shen Fuchou suggested that patients with chronic obstructive pneumonia should be instructed to breathe regularly in clinic, so as to spit out the gas and increase the gas exchange efficiency in the body. The method is: when exhaling with round lips (pouting and exhaling), roll up your tongue and then pout and exhale slowly. In addition, abdominal breathing can be used to let more oxygen enter the lower lung and increase lung function.
The normal breathing of ordinary people depends on chest breathing, which is usually limited to the expansion of the upper chest and hardly moves below the abdomen. However, when abdominal breathing is used, it can drive the diaphragm down, make the abdominal organs follow the rhythm of breathing, make full use of the lungs, and achieve complete gas exchange. In this way, it can also promote the activation of brain cells.
In any case, good breathing means consciously "slow" and "deep" breathing. In order to give full play to the energy of respiratory organs, we should consciously deepen our breathing and avoid fast and shallow breathing.
Laughing often can improve immunity.
Laughter can improve immunity, and it contains a kind of power to release stress. Laughing more can reduce the emotional tension caused by stress and create a healthy state of mind and body.
People's autonomic nerves are inherently biased towards sympathetic nerves and are in a slight state of tension, which is the most ideal balance. When the sympathetic nerve works better, it will be refreshed and energetic. At this time, the inner anxiety and fear will also subside.
On the contrary, when full of stress, anxiety and fear will rise rapidly in the heart, and sympathetic nerves will become overexcited. When the sympathetic nerve is excessively excited, the blood vessels will contract, which may cause systemic hypoxia. Therefore, if you can keep your emotions in positive and happy thoughts on weekdays, you can keep your sympathetic nerves on the good side and let the negative emotions of stress and tension be swept away.
A valuable smile must be from the heart. But how can I smile from my heart? It depends on the grateful heart. As long as you have a grateful heart and say thank you gratefully, you can peacefully resolve your sadness and anger, and naturally you can smile.
Since the age of 30, brain cells have begun to decline, and modern people's work stress, mood, sleep, or chronic diseases caused by the instability of the three highs are easy to affect their brain power; The operation of the brain depends on the circulatory system. Therefore, choosing the most beneficial lifestyle for the cardiovascular system is fundamental to protect the brain from damage.
A posture that can inhale a lot of oxygen
When it comes to establishing a good posture, it is nothing more than "holding your head high and your chin back", but this posture is not easy to last, and the more reluctant you are, the more impossible it is. In fact, as long as you simply stand naturally, then spread your weight on your toes and learn the correct posture slowly, you can adjust to a good posture.
As long as you do this, things are quite simple and easy to do:
First of all, stand naturally, and the center of gravity is slightly distributed on the toes, but it is not to let the whole heel float, and the heel should stick to the ground. If you are a man, you can imagine that you are ready to reach for something very high on the shelf; Women can recall their posture in high heels. After the center of gravity is assigned to the toes, naturally stretch the waist so that the S-shaped spine is completely above the pelvis.
The way to detect whether one's posture is correct can be observed from the worn position of the sole. Generally speaking, the normal sole wear should be 33.
