How to relieve the heat of the dog days

Three days of small days, there are miraculous effects

Futian is the hottest, humid and hot day of the year. As the temperature has risen steadily, Futian has also come across a variety of health problems. The “Old Diseases” are the most difficult times. This year, from July 18, the test of high temperatures and intense heat will continue until around August 17. How can you live a healthy and safe life? Yang Li, professor of health at the China Academy of Chinese Medical Sciences, Shen Yanying, professor at the China Health Education Center, and Zhuang Ganzhu, associate researcher at the Chinese Association of Chinese Medicine teach you six things to do against the dog days.

三伏天养生

Fan, cooling is better than air conditioning

The air conditioner can quickly cool down, but often blowing air conditioning will affect people's perspiration function. Yang Li told the reporter that perspiration is the process of cooling the body's self-regulation. Staying in the air-conditioned room for a long time, the body's ability to regulate the temperature will be reduced, and the ability of the central regulator to decline will cause all kinds of discomfort. Therefore, it is better to open the air conditioner less and use a fan instead to cool it. You can also open more windows. Accelerating air circulation also helps cool down. In particular, the elderly, due to the weakening of the body, have limited ability to adjust the temperature, and even less need to blow air conditioners. Also need to be reminded that even if you blow air-conditioning, do not blow all day long, you can open for a while and then turn off, the temperature should not be adjusted too low, to ensure that the indoor and outdoor temperatures do not exceed 7 °C, while taking care not to let the air conditioner blows directly to the body.

Green tea, replenish water while going to the fire

The weather is warm and the body is prone to dehydration, so a large amount of water is the best way to prevent heat stroke. Shen Yanying said that when replenishing water, you can choose to drink green tea. Because the human body in Futian loses not only water, but also many electrolytes will be lost. Green tea not only has the effect of heat and heat, but also contains a variety of vitamins and minerals that can quickly replenish the body's loss of electrolytes, thereby maintaining the body fluids dynamic equilibrium. In addition, green tea can eliminate tiredness and refreshment. If you should not drink tea, you can add some salt in the boiled water, you can also eat watermelon, drink mung bean soup and other ways to add water, but green beans cool, for children, not a lot of drinking.

Cotton underwear, strong sweat

The study found that the coolness of summer clothes is related to the sweat-wicking ability of clothes. Cotton clothes are not only comfortable, soft, but also strong in sweat absorption. Therefore, V-day wear cotton clothes can accelerate the absorption of sweat discharged from the body, quickly take away the body's heat, so as to achieve the effect of reducing body temperature. Yang Li reminded that clothes should not be worn too tight, loose clothing can also allow sweat to quickly leave the body surface. Dark clothes have a good ability to absorb heat and can choose lighter clothes such as white, light yellow, light pink, light blue and other colors. When you go to bed, do not be shirtless and wear pajamas so that you can protect your abdomen and prevent “wind evil” from entering the body and damaging your internal organs. It should be noted that if you wear less, you must be cool. When the temperature is higher than 37°C, the skin will not be able to dissipate heat, but it will also absorb the heat from the outside world. Therefore, to some extent, summer men should not go out of their shirts. Do not go through a short skirt.

A warm bath, better than the shower

Hot weather, many people will choose to bathe in cool water directly, in fact, this is not the correct approach. Zhuang Ganzhu said that when the weather is high and the pores of the body are in a state of openness, the metabolic rate is also faster, and the showering will cause the temperature of the skin surface to suddenly drop, the pores to close, the blood vessels to shrink, and body heat unable to escape. After washing, not only can not play the role of lack of relief, but also may make people limb weakness, shoulder and knee pain, and even induce arthritis and chronic gastroenteritis. Therefore, it is best to take a warm bath, and the water temperature is 35°C~37°C. This temperature is higher than the skin temperature, but lower than body temperature, ideal for cooling heat. It should be noted that some elderly people are afraid of catching cold and choose to wash with hot water. This is actually not true. Excessive temperatures may reduce the amount of oxygen in the bathroom and prone to syncope due to lack of oxygen. Therefore, the bath temperature should be warm water.

Mung bean, dampness and spleen

Hot and humid days are heavier, easily causing spleen deficiency, and spleen should be taken care of. Shen Yanying said that the diet should be mainly light, mung bean has the effect of spleen, you can properly drink some green bean soup to dampen the spleen. Traditional Chinese medicine also believes that mung bean soup has therapeutic effects such as relieving summer heat, clearing away heat and detoxifying, and has a good therapeutic effect on mild heatstroke, dizziness, headache, shortness of breath, shortness of breath, and no sweating. In addition, you should eat more fruits and vegetables, especially fruits and vegetables with high vitamin content, such as tomatoes, watermelons, cucumbers and so on. People with solar dermatitis need to pay attention to this season, eat less photosensitive foods such as celery, spinach, etc., because these foods will accelerate the skin's sensitivity to light, increase the allergy to ultraviolet light.

Swimming, the best summer workout

The often-speaking "summer drills" do not allow everyone to exercise regardless of time, place, and circumstances. In the summer, the human body consumes a lot of energy. Exercises such as running, playing, and climbing must be performed in a defensive manner. It is best to perform some “low-key” exercises that will not only cause an exercise effect, but will not cause discomfort. Experts recommend swimming because the water's ability to dissipate heat is 15 times higher than that of air. When swimming, the body can maintain a constant body temperature and is not prone to heat stroke. In addition, there must be exquisite sports time in the summer. When the temperature is high and the sunshine is strong, it is not only easy to be sunburned, but also increases the risk of heat stroke and dehydration. Therefore, it is best to choose to go outdoors early one night, early morning and late evening when the temperature is relatively low and the sunshine is not so strong. During the exercise, pay attention to replenishment in small amounts, and drink 100 ml to 150 ml of water every 10 to 15 minutes.
