with more and more haze weather, people’s pursuit of fresh air is becoming more and more intense. Recently, an enterprise launched a bottled oxygen rich weak alkaline water, claiming that the dissolved oxygen content in the water is 6-10 times that of ordinary water, which can effectively supplement the oxygen needed by the human body, and open up a new way for human beings to extricate themselves from the polluted water and air. Can drinking “oxygen enriched water” really help replenish oxygen? In fact,
can not solve the problem by drinking “oxygen enriched water” in order to avoid haze and breathe fresh air.
oxygen enriched water is not a new concept. It has been used for a long time in foreign countries. In foreign countries, this kind of water was first developed for athletes. Due to the large amount of physical activity and oxygen consumption of athletes, some sports scientists and businesses have thought of developing a water rich in oxygen to help athletes supplement oxygen while drinking water, hoping to improve the level of competition. However, many human studies have found that these so-called oxygen enriched water can not help athletes improve their performance.
this oxygen rich water claims that its high concentration of dissolved oxygen can quickly diffuse through the gastrointestinal mucosa into tissues and blood, so as to improve the partial pressure of blood oxygen and blood oxygen saturation, which has a significant effect on improving the symptoms of hypoxia. Do you really have such a good effect? Drinking oxygen enriched water to supplement oxygen seems attractive, but there are many questions. First of all, the solubility of oxygen in water and blood is very low. Oxygen in water is called dissolved oxygen (do). Dissolved oxygen in water refers to the oxygen element dissolved in water in molecular state. However, the solubility of a gas (such as oxygen) in a liquid (such as water) is limited. It must be proportional to the equilibrium pressure on the liquid surface. This is the basic law of physics, namely Henry’s law. Generally speaking, at a standard atmospheric pressure, the amount of dissolved oxygen in water is only about 0.68 ml / dl. In the actual production process, we can increase the amount of dissolved oxygen in water by increasing the pressure of oxygen. However, if the pressure is reduced, for example, when the cap of the bottled oxygen rich water is opened, the oxygen in the water will be released. Just like when we drink carbonated drinks, the gas carbon dioxide will come out when we open the bottle cap. It’s just that the water is filled with oxygen, while the carbonated drinks we usually drink are filled with carbon dioxide. Secondly, oxygen in water can not be well absorbed by human body. Human is a mammal, human breathing is through the lungs, oxygen into the alveoli for gas exchange, and then into the lung blood, and then through the blood circulation to all parts of the body. After drinking water, the water enters the gastrointestinal tract. Although a little oxygen may enter the blood circulation, the gastrointestinal tract is the gastrointestinal tract after all, which is different from the lung. Oxygen absorption through the gastrointestinal tract is very few. We humans, after all, are not fish living in water. Therefore, drinking water does not significantly increase the concentration of oxygen in the human blood.
however, many people may say, after all, the air is too bad now. Maybe it’s good for me to drink a few bottles of this water? In fact, the oxygen provided by drinking a few bottles of water is really very small compared with the oxygen you breathe in every day. Foreign studies have investigated the oxygen enriched water sold on the market, and found that the most common oxygen enriched water on the market is 80 ml oxygen per liter of water. When breathing, the average adult breathes about 500 ml of air each time. Oxygen in the air accounts for about 20%, and there is about 100 ml oxygen in one breath. In other words, the amount of oxygen we breathe in is higher than that of drinking a liter of oxygen enriched water. And this kind of water, even if the water you drink every day is this kind of oxygen rich water, generally no more than 3 liters, the oxygen contained in it is really insignificant for us who breathe all day. Therefore, it is impossible to improve the breathing air by drinking water. The harm of
haze on health should not be ignored. The international agency for research on cancer (IARC) of the World Health Organization (who) has issued a report that air pollution “causes cancer to human beings”. Although specific to everyone, the risk of carcinogenesis of air pollution is not high, but the impact of air pollution is large, the harm can not be ignored. The main cause of haze is environmental pollution. Because the haze can’t breathe fresh air, and want to solve it by drinking water, it’s a bit of a headache. Environmental pollution will also make water pollution, if we want to breathe fresh air, we still have to start from the treatment of environmental pollution!
