Why is oxygen so important for the human body? What conditions predispose to hypoxia?

Because oxygen enters the lungs, it will combine with hemoglobin and then transport it to various tissues of the body, providing energy and heat for the human body and maintaining the most basic metabolism of the human body, so oxygen is very important; In a plateau environment, in a confined space, if you work for a long time without rest, or when there are certain diseases in the body, it is easy to cause hypoxia.

Because oxygen supports the overall operation of the human body and is one of the main substances for human survival. In the case of severe cardiovascular and cerebrovascular diseases, allergies, asthma, food poisoning, upper respiratory tract inflammation, heart failure, etc., it is particularly prone to hypoxia.

Because we live on oxygen, and without oxygen, people will die; In a closed environment, when you are sick, when you are greatly injured, when you are covered by someone, and where the air pressure is very high, you are very prone to hypoxia.

One is that the oxygen supply is insufficient, and the other is that there is a barrier to the use of oxygen. Therefore, hypoxia is mainly caused by the following reasons:

1. Insufficient oxygen inhaled, including insufficient oxygen concentration inhaled, such as insufficient oxygen inhaled per unit time due to people in a high-salt environment or lung diseases. For example, there is chronic obstructive pulmonary disease, asthma, etc., or there is respiratory muscle paralysis, thoracic deformity, etc.

2. There is not enough oxygen available in the blood. These include a decrease in the amount of hemoglobin leading to an inadequate ability to transport oxygen, as well as a decrease in the ability of hemoglobin to transport oxygen, common causes of anemia and carbon monoxide poisoning.

3. The amount of tissue oxygen ** is reduced. Common causes include decreased cardiac output due to cardiac insufficiency, and decreased oxygen transport to tissues and organs per unit of time.

4. Tissue or cell oxygen utilization disorder, common hydride poisoning leads to tissue oxygen utilization disorder.

People who are heavy on mental work.

People with heavy brain power will excite the sympathetic nervous system when they use their brains for a long time, excessive stress, excessive tension or anxiety, which will make a large amount of adrenaline secreted, enhance metabolic ability, increase oxygen consumption, and when the inhaled oxygen cannot meet the demand, it will make the brain lack oxygen. In addition, prolonged lack of exercise, long-term stay in a confined environment, poor cardiorespiratory capacity, and excessive reliance on electronic devices can cause the body to lack oxygen. In addition, cerebral infarction, trauma to the brain, and chronic obstructive pulmonary disease (COPD) can prevent the lungs from supplying oxygen, resulting in pathological hypoxia.

Prolonged lack of exercise, prolonged stay in a confined environment, poor cardiorespiratory capacity, and excessive reliance on electronic devices can deprive the body of oxygen. People with heavy brain power use the brain for a long time, excessive pressure, excessive tension or anxiety, etc., will excite the sympathetic nerves, make a large amount of adrenaline secretion, enhance metabolic ability, increase oxygen consumption, inhaled oxygen can not meet the demand, it will make the brain lack oxygen.

People can't live without oxygen for a moment, and they can't go on without it for three minutes. Although oxygen is readily available, some patients still suffer from hypoxia, whose main symptoms are dizziness, headache, difficulty concentrating, memory loss, and poor sleep quality.

Everyone knows how important oxygen is to life. Oxygen enters the lungs by breathing, binds to hemoglobin, and then transports to various tissues of the body, where it is catalyzed by enzymes and reacts with glucose to release carbon dioxide, energy and water to provide energy for the body and maintain the most basic metabolism. If the lack of oxygen for a long time is not treated in time, it will bring unexpected damage to the body.

When there is a lack of oxygen in the histiocytes, it can reduce immunity and cause small problems. Digestive symptoms such as constipation, decreased appetite, and stomach bloating and stomach pain can occur when there is not enough oxygen in the blood. In mild hypoxia, breathing will increase in speed, and in severe cases, breathing difficulties and chest tightness and chest pain may occur.

The central nervous system is most sensitive to hypoxia, which can cause dizziness, headaches, and loss of doing things.

1. Eat more oxygen-producing foods.

Blood oxygen protein supports oxygen, so you should eat more iron-containing foods such as legumes, lean meat, fish, fresh vegetables and fruits. In addition, raise more green plants at home, because green plants can absorb carbon dioxide and release a lot of oxygen during photosynthesis.

2. Exercise cardiopulmonary function.

If you want to alleviate the problem of hypoxia, you should improve your cardiopulmonary function, recommend exercise, and insist on aerobic exercise combined with strength exercises, such as brisk walking, jogging, and swimming. The elderly should take more walks, which can effectively improve cardiopulmonary function, relieve dyspnea and chest tightness and shortness of breath, and do not do strenuous exercise, otherwise it will aggravate their symptoms.

When I first began to recognize the effects of oxygen on my health, a question came to my mind: how does the body use oxygen?Now with this question in mind, let's take a look at it together!

Step 1: Evolve to create a respiratory system for the body to obtain oxygen from the air. <>

The purpose of the respiratory system is to provide a continuous supply of oxygen to the body, and the entire lung is constructed to obtain oxygen, and the lung is the most important organ of the respiratory system.

The difference between the air pressure inside the lungs and the atmospheric pressure allows air to enter the lungs smoothly, and the rhythmic contraction and relaxation of the respiratory muscles in the lungs allow for regular exhalation and inhalation.

Through the pressure difference and the action of the respiratory muscles, the outside air passes through the nose and trachea to the alveoli inside the lungs. The oxygen in this air is exchanged with the alveoli for gas.

Step 2: The oxygen from the alveoli is exchanged with the venous blood flowing through the lungs.

This converts venous blood into oxygen-rich arterial blood. At this point, oxygen enters the circulatory system from the lungs. Through the blood circulatory system, the oxygen breathed in is transported to all tissues and cells throughout the body for use. <>

Because red blood cells are used as carriers to transport oxygen throughout the body, the main component of red blood cells is hemoglobin, which is mainly composed of iron and protein.

When nutrient deficiencies occur, it leads to a decrease in red blood cell production. Anemia is the most common phenomenon and will reduce the amount of oxygen transported, which is directly caused by the lack of oxygen**.

The heart is the power center of the body, the brain is the command center of the body, these two organs have the largest oxygen consumption, and the demand for oxygen is also the most sensitive. <>

Step 3: Through the circulatory system of the blood, oxygen leaves the lungs and is transported to all tissues and cells of the body.

Ponder the question: 1. Do you feel that you have a chronic lack of oxygen in your body?

2. How does high oxygen deficiency affect physical health?

3. Think about it, do you often hold your breath inadvertently, especially when you are nervous?

4. Where you live, where you work, and how well the air is circulated? How can it be improved?

5. Do you often come into contact with nature, go to the countryside, go to places with high negative ions, and breathe fresh air?

6. Observe those around you who are suffering from chronic diseases; the timid and fearful; people who are easily angry and fearful; stingy people; Do they all share a common trait that shows symptoms of hypoxia, short, shallow breathing, and often holding their breath?

7. Teach yourself to breathe deeply, right now?
