Why are you lacking oxygen? Spell it out once and for all
What causes the lack of oxygen?
1, modern life has made us hypoxic;
2, the environment of decreasing oxygen source and increasing oxygen consumption;
3、Natural anoxic environment of physical factors;
4、Pathological hypoxia.
Q: Why does modern life make us hypoxic?
A: Poor living habits can cause hypoxia can cause systemic hypoxia, can also cause local hypoxia, can cause chronic hypoxia and acute hypoxia, but most of them are mild systemic chronic hypoxia, such as insufficient exercise or overload exercise, smoking, excessive high-fat meals, long-term addiction to a single simple operation, sleeping head, pillow too high.
1, insufficient exercise: Today, the need to directly use the body to maintain life less and less activities, the distance is also close to the car, up and down the stairs to take the elevator, resulting in reduced movement, blood circulation function gradually weakened. Blood vessels become thinner, and the ratio of blood vessels to cells is gradually reduced, thus becoming a tissue structure prone to hypoxia, and our bodies are gradually deteriorating into hypoxia without realizing it.
2、Diet imbalance: High-fat meals, modern people eat processed fine things, vegetables and fruits cultivated with chemical fertilizers, a variety of readymade foods and frozen foods, overeating, resulting in abnormal body shape, obesity, causing a great burden on the internal organs, synthetic coloring materials, preservatives, synthetic seasonings absorbed every day also need a lot of oxygen, the body increases harmful substances, It further increases the burden on the liver and kidneys, because the liver needs to detoxify, and the kidney needs to detoxify. If it can't be excreted, it can cause disease.
3, a long time single operation: the human body is composed of many different functions of tissues and organs. The function of the organ needs continuous use to maintain, that is, to retire, if a single organ is used for a long time, and the function of other organs is gradually degraded due to low metabolism, once occasionally excessive use will appear relative hypoxia, due to hypoxia can produce anoxic damage.
4, the pillow is too high: high pillow induced hypoxia, because the pillow is too high supine position will make the back of the tongue fall, resulting in upper respiratory tract obstruction, due to poor breathing, the lung gas exchange is reduced, the blood oxygen content is decreased, especially in obese people. The upper respiratory tract obstruction is more serious when obese people sleep with high pillows, so there is always a certain causal relationship between obesity, hypertension, high pillows and hypoxia.
Q The environment of decreasing oxygen sources and increasing oxygen consumption?
A: The oxygen source is mainly plants, and there are various oxygen consuming substances, where there is combustion, oxygen is consumed. However, the number of plants producing oxygen on the earth is decreasing, and various substances consuming oxygen are burning, including biological combustion, biological combustion is animals, but the number of animals is increasing; Physical combustion such as smelting, blasting, traffic and other open flame. In the past 50 years, oxygen sources have rapidly decreased and trees have been cut down. The skin graft was greatly reduced, especially the oxygen source was greatly reduced. And the main reason for the increase of oxygen consumption in modern living environment is air pollution. Many pollutants consume large amounts of oxygen. In addition, the air circulation in modern buildings and vehicles is not smooth, and the air pollution caused by heating and cooling facilities, the result is that every cell in the human body suffers from the reduction of indoor oxygen supply.
Q Physical factors in the natural anoxic environment?
A:Physically, the oxygen concentration in the air is proportional to the atmospheric pressure, that is, the oxygen pressure in the air is high when the pressure is large, and the oxygen pressure in the air is low when the atmospheric pressure is low. The natural variation of atmospheric pressure has climatic factors and geographical factors. The oxygen concentration in the air is related to the temperature, that is, the oxygen concentration in the air will be lower when the temperature is high, and the oxygen concentration in the air will be higher when the temperature is low. It is inversely proportional to the humidity of the air, that is, the higher the humidity of the air, the smaller the oxygen content of the air.

Climate factors: cloudy days are prone to hypoxia, because the atmospheric pressure is lower on cloudy days, and the oxygen concentration in the air will be lower on cloudy days because the humidity in the air is large. Third, the oxygen concentration in the air in hot days with high humidity will be low, the so-called hot weather, that is, the temperature is high, there is no wind, and the oxygen concentration in the air will be low when the humidity is high, and it is easy to be hypoxic.
Geographical factors: The air at high altitudes is thin, that is, the air pressure is low, and the partial pressure of oxygen in the air is low.
Small environmental factors: poorly ventilated living rooms, offices, restaurants, bedrooms, public places, especially more people, and poorly ventilated indoor, transportation, plus someone smoking is even worse.
Q Pathological hypoxia?
A: Caused by various pathogenic agents or diseases. Pathological hypoxia includes anoxic hypoxia, blood hypoxia, circulatory hypoxia, tissue toxic hypoxia and increased oxygen consumption hypoxia.
1, anoxic hypoxia: seen in drowning, injury, excessive obesity, serious nasopharyngeal proliferative diseases, asphyxia, such as insufficient alveolar ventilation, airway obstruction, and even respiratory arrest caused by hypoxia; There are respiratory diseases such as bronchitis, emphysema, pulmonary heart disease, bronchial asthma, lung infection and so on to make alveolar ventilation perfusion ratio imbalance, alveolar wall dispersion function decline caused by hypoxia are called anoxic hypoxia, can also be said to be exogenous hypoxia, that is, not enough oxygen combined with blood.
(2) Blood hypoxia: It refers to the hypoxia caused by the decreased ability of blood to transport oxygen. Such as various causes of anemia, acute blood loss, carbon monoxide and a variety of harmful gas poisoning, nitrite poisoning. The first two conditions are insufficient oxygen-transporting hemoglobin, and the latter is related to impaired oxygen-transporting capacity of hemoglobin.
3, circulatory hypoxia: refers to the systemic or local tissue of effective circulation of insufficient blood volume caused by hypoxia. Systemic hypoxia of blood circulation is seen in various heart diseases, severe bradycardia, arrhythmia, heart failure, various shock, cardiac arrest, anesthesia accidents, etc. Local circulatory hypoxia is seen in blood vessel obstruction caused by the formation of gas suppositories, thrombus and fat suppositories, vasculitis, varicose veins, vasospasm, severe blood hyperviscosity, and local blood supply disorders caused by perivascular compression can cause local circulatory hypoxia.
4, cellular hypoxia: there are three cases (1) oxygen can be transported to the tissue with the blood, but oxygen can not be dissociated, oxygen can not be combined with the cells that need oxygen, such as CO poisoning is this case. (2) Due to histiocytic edema, the distance between histiocytic cells and capillaries increases, exceeding the available range of oxygen diffusion force, resulting in hypoxia, which is seen in edema caused by various reasons, often in brain edema and pulmonary edema. (3) Although oxygen reaches the cell, because the cell can not benefit from oxygen due to poisoning, it can only carry out anaerobic metabolism, such as cyanide poisoning, CO poisoning, etc.
5, increased oxygen consumption hypoxia: refers to the relative hypoxia caused by a significant increase in oxygen demand in a short period of time. Such as strenuous exercise, high-intensity labor, pregnant women, students before the exam and nervous mental work, fear and panic, extreme sadness may occur relative hypoxia. Hypoxia occurs when the body needs a significant increase in oxygen if it is not replenished in time. Light can gradually recover after rest, and heavy can produce degenerative changes.
Hypoxia is the root of all diseases, mild chronic hypoxia, began to appear as a sub-health state, that is, mainly a variety of subjective symptoms, fatigue, decreased work efficiency, physiological dysfunction, general discomfort, but the examination or laboratory examination failed to find any organic diseases, but a long time will appear a variety of diseases.
