As the saying goes, “winter three nine, summer three volt”, meaning that the volt days to do a good job of health, a whole year are less sick. So along with the ambush, the most crazy circle of friends forwarded is a variety of ambush day health post: three ambush days to “sit on the moon” way to health, hot water soaking feet, can not drink cold drinks must drink hot tea, can not blow air conditioning …… these reminders are correct? 1, never drink iced drinks three volt not eat “ice” is too absolute Recently, the circle of friends circulated a message: “three volt days, do not drink iced drinks, or will make the cold invasion can not be discharged. To make the body’s cold discharge, to insist on drinking hot water on the day of ambition, so that the body will be forced out of years of deep marrow cold.” This statement is too absolute. This message of the circle of friends is similar to a pseudo-proposition. The three volt days of summer are the time when nature and the body’s yang energy are at their peak, and the hottest season of the year. One of the principles of Chinese medicine health care is to follow nature, and the heat is hot in summer. When the body’s yang energy is at its peak, the use of cold products (cold drinks, air conditioning) to resist, will inevitably deplete the body’s yang energy, damage the body’s spleen and stomach function. Now some health posts always use some very absolute point of view to attract attention, in fact, is also a kind of health misunderstanding. In summer, the temperature is high, people can not stand the heat, at this time to drink a little chilled drinks or eat a little chilled watermelon or popsicle, both to relieve the heat, but also to make people feel comfortable, it is also not bad, the key is not too greedy cool, if you can not wait to eat a few popsicles in one gulp, ton are drinking cold drinks, that is certainly harmful to the body. In addition, there is a view that the volcano day to insist on drinking hot water, so as to force out the cold in the body for many years deep into the marrow. In this regard, Li Zhi also pointed out that the key to drinking hot water is the body. If the body itself is cold, this person in the summer when everyone feels very hot, he feels the need to wear a long-sleeved to warm, then he will feel more comfortable in the summer to drink some hot water. But if the body itself is hot, the summer has been moving all over the sweat, at this time must drink hot water is undoubtedly suffering. 2, voodoo days to sit in the moon style to prevent heat is still the first traditional way to sit in the moon has been criticized for a long time, but now some health posts call on everyone in the three voodoo days to take this way to health. In this regard, experts pointed out that the moonbat style over the voodoo days this argument is too unreliable. The traditional way of sitting on the moon is often said “can not open the window, can not blow”. But the fact is that the “three volt days” is the highest temperature of the year and humid, hot days, when the most prone to disease is heat stroke. In addition to the hot and sunny outdoors, hot and humid, poorly ventilated indoor is also a place where heatstroke is common, so be vigilant and pay attention to preventive measures. Some people think that since it is easy to get heatstroke in the hot sun outdoors, it should be safe to stay indoors to escape the heat. In fact, heatstroke does not only occur outdoors in high temperatures, but also indoors in humid, hot, poorly ventilated rooms. Some studies have shown that when the ambient temperature reaches above 32°C and the air humidity is above 40%, people are prone to heat stroke. Therefore, if the indoor ventilation is not enough, the humidity is too high, the body sweat can not evaporate out in time, the same will be heatstroke. This kind of health post claims that the most important thing in the three volt days is not to prevent heatstroke, but to prevent cold. The first thing is to prevent heat, but this does not mean that summer does not need to prevent cold, for many people who like to eat cold drinks in the summer, love to blow air conditioning, like the cool, cold work or need to pay attention to. Never blowing air conditioning 24 hours a day, from the outdoors back to the air conditioning room, it is best to first adjust the air conditioning to a higher temperature and then gradually lower, so that the body slowly adapt to the air conditioning temperature is best with the outside temperature difference of more than 8 ℃. Do not sweat profusely when immediately enter the temperature is very low air conditioning room, sweat to enter the air conditioning room first change out of wet clothes, wipe dry sweat. 3, a bowl of lamb soup in volcano days without the doctor to prescribe summer eat lamb easy fire friends circle also spread a health post “volcano days a bowl of lamb soup, without the doctor to prescribe”, said three volcano days to eat lamb, drink lamb soup commonly known as “volcano sheep”, can The actual “heat to heat, sweating and detoxification”. The summer lamb soup tonic, only suitable for Yang deficiency of people, most people in the summer is Yang Sheng state, drink more lamb soup or eat more lamb, but will lead to dry stools, fire. Even if you are a Yang deficiency body, summer tonic also need to stop, do not make up. So, what is a healthy diet in summer? The summer heat, the human body due to thermoregulation, metabolism and circulation, digestion, neurological, endocrine and urinary system changes significantly, resulting in increased nutrient consumption, sweating and loss of water and nutrients, coupled with the summer people’s appetite for food, but also limit the absorption of nutrients. As a result, many people are weak in summer and lose their appetite. In summer, we should pay attention to some nutrients: first of all, we should increase protein intake, of which high-quality protein should account for more than half. Foods rich in high quality protein include lean meat, fish, eggs, milk, soybeans and soy products. Secondly, we should eat more food rich in potassium, calcium, magnesium and iron. Potassium deficiency is one of the causes of heat stroke, so the diet should be more with some potassium-rich foods, such as vegetables and fruits, beans, etc. Green vegetables, nuts and coarse grains are rich in magnesium. Milk and milk products, soybeans and their products are rich in calcium. Animal liver, lean meat, animal blood is a good source of iron, rich in good absorption. Also timely replenishment of water and salt. Drink water according to the amount of sweating, can not wait for thirst to drink water, to drink water regularly, a small number of times. You can use plain water, tea, lemon water, green bean soup, etc. If you sweat more, should be supplemented with salt, you can choose some sports drinks, or add some salt (0.1% salt content) in plain water and tea in moderation. 4, summer training three volt sweat out of the comfortable summer training three volt take it easy “winter training three nine, summer training three volt” is the verbiage of many elderly people exercise, especially in the volcano days, avenue, park everywhere you can see the storm to sweat dripping elderly people. Many health reminders have said: “Let the sweat out of the comfortable, in order to achieve the fitness effect.” Fitness can not blindly pursue the thrill of exercise, especially in the summer sweating, consumption of large conditions, fitness should pay more attention to grasp the degree of exercise, so as not to consume too much, some of the functions of human damage. Summer to sweat properly, but not to exercise to dripping sweat is good, in fact, it is easy to cause dehydration. At the same time, after the summer exercise, human body temperature is significantly higher, coupled with the impact of hot weather, it is easy to heatstroke, so the general public should avoid extreme exercise and anaerobic exercise, it is best to use aerobic uniform exercise, heart rate control in the small exercise area, that is, about 120 times / per minute can be. The elderly should also slow down a bit, because the elderly if excessive exercise in the summer, sweating will lead to thick blood, coupled with the heat, it is likely not healthy body, but lead to heart disease, cerebral infarction. Long hours of exercise in the sun in the summer will intensify the disorder of water and salt metabolism in the body. Therefore, before, during and after exercise should drink some light salt water or sports drinks, about 50 to 100 ml every half hour. In addition, summer sports are more appropriate to choose the morning or evening, the location of the choice in the shaded places. The duration of exercise should not be too long, to 30 minutes to an hour is appropriate, according to personal fitness and exercise intensity appropriate adjustment.
