How does hypoxia occur?
The oxygen content in the air is proportional to the atmospheric pressure, that is, the oxygen content in the air is high when the atmospheric pressure is high, and the oxygen content in the air is low when the atmospheric pressure is low.
The variation of atmospheric pressure is related to climatic factors and geographical factors. The oxygen content in the air is also related to the temperature, that is, the oxygen content in the air is lower when the temperature is high, and the oxygen content in the air is higher when the temperature is low. The oxygen content of the air 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.
How does hypoxia occur?
1. Geographical factors:
At altitude, the air is thin, that is, the pressure is low, and the oxygen content in the air is low.
2. Climate factors:
Sauna day is a hot and humid weather, the oxygen content will be low, easy to hypoxia. Cloudy days are prone to hypoxia, because the atmospheric pressure is lower on cloudy days, and the oxygen content in the air is lower; At the same time, the humidity in the air is high on cloudy days, so the oxygen content in the air will be low.
3. Working and living environment factors:
Poor ventilation of living rooms, offices, restaurants, bedrooms, public places, especially more people, and ventilation without indoor, transportation and smoking environment, oxygen content is even worse.
Lack of oxygen due to improper diet
1. Overeating and obesity:
Overeating can cause a great burden on the internal organs, first of all, the burden of the stomach, and then the burden of the liver and kidneys.
Overeating will increase oxygen consumption, in order to excrete these harmful substances, it needs a lot of energy, and the generation of energy needs a lot of oxygen, in order to neutralize the synthetic colors, preservatives, synthetic seasonings unconsciously absorbed every day also need a lot of oxygen, the increase of harmful substances in the body will further increase the burden on the liver and kidneys. Because the liver needs to detoxify, at the same time, the kidney needs to detoxify, if it cannot be discharged, it will cause disease. When obesity increases the body's load, oxygen consumption increases, and the blood vessel/cell ratio decreases when obesity, it is easy to occur chronic hypoxia and promote cell aging.
2. High fat diet:
After eating excessive greasy food, a large amount of fat enters the blood, which can slow down the blood flow and even cause cell fat embolism, thereby causing local hypoxia.
In our lives, many people are suddenly deaf after a big meal. The formation of severe hyperlipidemia after eating and drinking, resulting in reduced blood supply and oxygen supply to the inner ear, coupled with the toxic effect of alcohol on the auditory nerve, causing sudden hearing loss. Some people also suffer from cerebral infarction, angina pectoris or acute pancreatitis after eating a large number of fatty meals.
Lack of exercise leads to hypoxia
In modern society, urban people need to directly use physical activities to maintain life less and less, walking to and from work by car instead; Walk up and down stairs instead of elevators. If you do not exercise for a long time, the systolic function of blood vessels in the body will decrease, the contractility of the myocardium will weaken, the blood vessels will become thinner, the body fat will accumulate, the perfusion volume of blood vessels will be relatively reduced, and the ratio of blood vessels to cells will gradually decrease, thus becoming a tissue structure prone to hypoxia, and the blood supply to the tissue is relatively insufficient.
Those who insist on exercise will only appear relative hypoxia when they exercise vigorously, and those who do not exercise for a long time will appear hypoxia as long as they are slightly active.
Sleep and hypoxia
1, sleep in worry:
People spend 1/3 of their lives in sleep, and the posture of sleep has a great impact on people's health.
According to relevant statistics, people who are used to sleeping high, the prevalence of obesity and hypertension is higher. Hypoxia can cause obesity and hypertension, and high pillow sleep can induce hypoxia.
Why can high pillow sleep induce hypoxia?
Because the pillow is too high, the back of the tongue will fall, resulting in upper respiratory tract obstruction, because of poor breathing, the lung gas exchange is reduced, and the blood oxygen content is decreased, especially in obese people.
When obese people sleep with high pillow, upper respiratory tract obstruction is more serious, so obesity, hypertension, high pillow, hypoxia always exist in a certain causal relationship.
2. Cover your head and sleep:
When sleeping, be sure to expose your nostrils to inhale the indoor air, and the bedroom window must be partially open, preferably with a little convection.
Many people are afraid of cold in winter, the doors and Windows are tightly closed, and they sleep with their head covered, the oxygen concentration of the gas inhaled is low, the concentration of carbon dioxide is high, and this sleep mode is easy to have nightmares, when having nightmares, oxygen consumption will be more, oxygen consumption will be less and oxygen consumption will be relatively hypoxia.
Smoking and hypoxia
Smoking will inhale a lot of carbon monoxide, carbon monoxide in the blood and oxygen to compete for hemoglobin receptors, because carbon monoxide and hemoglobin affinity is 360 times larger than oxygen, so smoking inhalation of carbon monoxide will be the first to bind to hemoglobin, so that hemoglobin carries carbon monoxide, rather than oxygen.
Smoking inhalation of carbon monoxide makes part of the blood lose the function of transporting oxygen, and the hypoxia caused by this is a mild chronic hypoxia. Smokers have relatively chronic hypoxia. The degree of hypoxia is proportional to the amount of smoking, and the more you smoke, the greater the harm.
The lungs are the place where the human body carries out gas exchange, oxygen enters the body through the lungs, and good lung function is the basic condition for the human body to avoid hypoxia.
In long-term smokers, the exchange capacity of the alveolar walls is reduced, and the efficiency of oxygen and carbon dioxide exchange within the lungs is reduced. Severe hypoxia occurs when long-term smokers develop chronic bronchitis, bronchitis, pulmonary fibrosis, pulmonary heart disease, bronchospasm, and bronchial stenosis.
Oxygen therapy is a green, safe and well-tolerated method of oxygen supplementation.
1,The physical dissolved oxygen in the body multiplied, tissue oxygen reserves increased, oxygen diffusion rate and effective dispersion distance increased, more able to produce strong enough penetration, is the most direct and effective treatment method to improve ischemia and hypoxia.
2, inhibit the growth and reproduction of anaerobic bacteria, and have an inhibitory effect on some aerobic bacteria. In addition, it also enhances the bacteria-eating ability of white blood cells, and can enhance the antibacterial action of some antibacterial drugs.
3, improve microcirculation, regulate cell cycle, etc. Hyperbaric oxygen can be used to treat diseases caused by ischemia and hypoxia of body tissues, organs and cells caused by various factors, and it has a regulatory effect on all systems of the body.
