What kind of water is most assured to drink in summer?

The problem of drinking water has always been a concern of human beings. In summer life, due to the hot climate and excessive sweating of the human body, most people have the problem of insufficient drinking water. Therefore, in summer, avoid drinking water when you feel thirsty, and you should drink water often. The daily intake of water from diet and drinking water by a normal person is about 2500 ml/day for adults, and the amount of water intake should generally be balanced with the daily excretion of water from the human body. For example, the average daily urine output of adults is about 1500 ml, the skin and respiratory tract excrete about 800 ml, and the stool is 100-200 ml, totaling about 2500 ml. Therefore, normal people need to drink about 1500 ml of water every day in addition to meals. About 6 to 8 glasses of water can meet the needs of human metabolism. Since water is so important to human beings, the quality of the water people consume every day is a crucial issue, which is directly related to human health.

At present, experts are inconsistent on whether it is better to drink pure water or tap water. Some experts believe that drinking water is to replenish water, there is no need to consider nutritional issues. Other experts believe that there are many trace elements and inorganic salts in tap water, which are beneficial to the human body. So what are the nutrients in tap water? The content of zinc and iron in 1000 ml of water is less than 0.2 mg. Adults need to supplement zinc 10 mg-15 mg and iron 12 mg-18 mg daily. The daily intake of trace elements from water is less than 1 mg, which is insignificant compared with the trace elements required by the human body. However, the water contains high calcium and magnesium elements, which are still beneficial to the human body. Since real pure water is filtered through multiple layers, impurities, trace elements, inorganic salts and disease-causing bacteria are generally removed from the water. It is safe, non-toxic, non-polluting, and hygienic. It is good for the human body, but the missing elements can be Ingest from food. Therefore, if economic conditions permit, the purchase of truly pure water is human progress. However, because the production of purified water is very irregular and mixed with fish, if you buy substandard products, it will be harmful to your health.

Bottled water such as purified water and mineral water is favored by modern people because of its convenience for drinking. When the bottled water once again caused trouble for people, many people began to boil it to drink. Liu Yumin, director of the Environmental Health Institute of the Beijing Municipal Center for Disease Control and Prevention, told reporters that as long as the tap water is up to standard, it is safest to drink after boiling. Experts remind that bottled water should be "drinked fresh". Bottled water such as distilled water, mineral water and other purified water on the market will usually be disinfected with ozone before being bottled. Therefore, just fill it. Bottled water will contain a high concentration of ozone, and the strong oxidizing nature of ozone is very harmful to human health. Therefore, it is best to store fresh bottled water for 1-2 days and drink it after the ozone dissipates. In addition, the bottled water is best consumed within a week after opening. Drink different water every week Today, many health experts advocate a new way of drinking water, that is, drink different water every week, and people of different family structures or different age groups drink water with different mineral content. Experts point out that if you drink one type of water for a long time, it will cause dizziness, weakness, weakness, etc., and the limited content of trace elements in a mineral water is not enough to provide the human body with balanced trace elements. Experts advocate drinking straight drinking water, which is healthy and healthy without worries. Because you can see that the water is pure by drinking directly
