The hot summer, the scorching sun, especially in Zhanjiang is located in the southeast coast, the summer humidity is particularly, because the summer is Yang evil, its nature is hot, easy to ascend and disperse, so sweat hole more open, often make the head and body sweat, sweat, exhausted gas injury, therefore, summer hydration becomes necessary, but how to hydrate is the key. A, avoid thirst before drinking water hot summer, many people a little activity, or even inactivity will sweat, we usually think a lot of water will be able to solve the problem of sweating water loss. But such a large amount of water can make the stomach full, hinder the diaphragm activity, affecting normal breathing, increase the burden on the heart, easy to cause palpitations, chest tightness and other symptoms. In addition, some people often drink water only when they feel very thirsty, when the body has been seriously dehydrated, the body’s organs have been operating in a limit, one will increase the incidence of cardiovascular disease, the second is easy to form urinary tract stones and urinary tract infections, the third is easy to make the skin dry, wrinkles increase, accelerating human aging, the fourth will cause dry stool, endotoxin, causing bloating, dizziness and other symptoms of poisoning. So remind friends, the summer season to timely scientific hydration, the daily water intake should reach more than 1000 ml, and to drink water regularly, in general, it is best to get up early in the morning, brush your teeth after a glass of plain water, a glass at 10 am, a glass before lunch, a glass at 3 pm, a glass before bed at night. Do not only think of drinking water when you are thirsty. Second, do not drink cold water or cold drinks Chinese medicine believes that the human body in the summer yang qi in accordance with the characteristics of the natural outward, therefore, drinking cold water will affect the nature of the rise of yang qi, to the qi stagnation is not through the pain. From a Western medical point of view, the water molecules of cold water are not easy to penetrate into the cells, while the water molecules of hot water can quickly penetrate into the cells and can replenish water in time. Cold drinks can cause vasoconstriction, injury to the stomach and intestines, cold drinks in sugar, milk, eggs, etc. to water to help dissolve digestion, in turn make the lack of water more serious. Therefore, remind everyone, when a lot of sweating and thirst, drink warm water or warm light (salt) tea water is appropriate. Third, avoid only know drinking water, do not know to supplement salt Our sweat contains a little more than 1% of salt. A lot of sweating can make the body lose too much salt, resulting in the body’s osmotic pressure is out of balance, this time drinking water can not stay in the cells, and with sweat to exclude, sweating and bring out the salt, so the vicious circle, can make the body a serious salt deficiency, easy to cause muscle weakness, pain and even convulsions. Therefore, remind everyone, should drink a small amount of light salt warm water, tea to supplement salt. Fourth, avoid drinking too much water to cause water poisoning. Drink less water can not, but excessive drinking water can also cause water poisoning, water accounts for about 65% to 70% of the body weight, and relatively stable in the body. The cell membrane of human cells is semi-permeable membrane, water can be freely permeable, if you drink too much water, blood and interstitial fluid will replenish the balance of release, osmotic pressure is reduced, water will permeate into the cells, so that the cells swell and water poisoning occurs. Once the brain cells are edematous, the pressure inside the skull will increase, resulting in dizziness, headache, vomiting, weakness, blurred vision, drowsiness, slowed breathing, decelerated heart rhythm, and in severe cases, coma, convulsions and even life-threatening.
