in hot summer, the human body sweats a lot and consumes a lot of physical energy. If you don’t pay attention, you will cause dizziness, sore throat and other symptoms. So, what measures should be taken to prevent heatstroke in summer? Let’s take a look at how to “make heat with heat” and reduce summer heat.
drinking hot tea
cold drinks can only relieve summer heat temporarily, can not relieve fever and thirst for a long time, and can not eat too much, otherwise it will reduce gastrointestinal temperature, cause irregular contraction, induce abdominal pain, diarrhea, etc. Drinking hot tea can stimulate the general relaxation of capillaries, but significantly reduce the body temperature. Studies have confirmed that drinking a cup of hot tea for 9 minutes can reduce the body temperature by 1 ℃ ~ 2 ℃, and the cooling can be maintained for more than 15 minutes.
therefore, drinking hot tea in summer is a simple and easy way to reduce summer heat. You can make tea alone, or drink fruit tea and flower tea. You can also wash 10 grams of dry orange peel, tear it into small pieces, put it into a cup with 5 grams of green tea, add boiled water and cover it for about 10 minutes, remove the residue, and add a piece of rock sugar before drinking. South Koreans have the habit of taking ginseng chicken soup in dog days, which is also an effective way to “make heat with heat”.
take a hot bath
take a cold bath in summer will shrink the skin capillaries and feel hotter after washing. Although hot water bath will sweat more, it can dilate capillaries, which is conducive to the body to dissipate heat, promote metabolism, accelerate the removal of lactic acid and other metabolites, and eliminate human fatigue. The water temperature is generally controlled at about 30 ℃.
hot water feet
hot water feet can open the pores of the whole body, which is conducive to heat dissipation. Therefore, soaking feet in hot water in summer can promote perspiration, enhance sweat gland function and improve heat resistance. Before going to bed every night, soak your feet in warm water at about 40 ℃ (the water drowns the ankle joint) for 15 ~ 20 minutes each time (during which you can heat the water to maintain the water temperature), so as to feel slightly sweating.
eat hot food
many people think that the weather is hot and some meals can be eaten without heating. This view is wrong. Hot and humid environment is easy to breed pathogenic microorganisms such as bacteria. Heating can play the role of disinfection and sterilization and protect people’s body from bacteria. When cooking, you can use some scallions, garlic, ginger and other seasonings to increase body perspiration and prevent heatstroke.
sweating
proper physical exercise can strengthen the heat resistance of the human body, improve the function of temperature regulation, enhance the physique and prevent heatstroke. In order to avoid heatstroke, exercise time in summer can be around 6 or 7 p.m. and fitness programs can choose swimming, walking and Taijiquan. Wear clothes made of pure cotton with good sweat absorption and air permeability during exercise. Wipe the sweat off your body after exercise and use the air conditioner after your body temperature recovers.
hot compress the navel
gently apply it on the navel with a hot water bag or hot towel with a temperature of about 40 ℃, take it off after a few minutes, and apply it 1 ~ 2 times a day, which is one of the ancient methods to treat heatstroke. You can also rub your hands on an empty stomach before going to bed every night, stack the palms on the lower left and upper right and stick them on the navel, and rub them counterclockwise for 20 ~ 30 circles each time.
sweating in temperature
sweating is the way for human body to dissipate heat. However, due to the universal application of air conditioning, sweat glands are almost idle for people who have been in a temperature stable environment for a long time. Even in the sweating season, they don’t sweat often in summer, which is harmful to health. In accordance with the rhythm of the four seasons and the law of life, you sweat when you sweat.
ginger has three effects: sweating and relieving the surface, warming and stopping vomiting and detoxification. Regular drinking of ginger soup has the effect of sweating and relieving summer heat. You can drink ginger silk in water or ginger slices in red tea every morning. You should not eat ginger at night.
clothes should not be too bare
clothes should not be too bare. In summer, people’s clothes are thinner and thinner, and more and more parts of their bodies are exposed. They think this can relieve the summer heat and cool. In fact, otherwise, when the external temperature is higher than the skin temperature, the skin will not dissipate heat, but will absorb heat from the external environment. For example, the exposed area is too large, Heat radiation is easy to invade the skin, but it is hotter. This is the reason why shirtless people feel hotter in summer.
experts suggest that in summer, you should wear light, breathable and loose clothes, preferably light color. The exposed area should not exceed 25% of the total surface area of the human body. When you go out, you should wear hats, umbrellas, sunglasses and long sleeved clothes and trousers as much as possible to protect your skin.
thermal air conditioner
adjusts the air conditioner to 25 ℃ ~ 26 ℃, which is a more suitable temperature for the human body, can avoid the discomfort caused by the large temperature difference between indoor and outdoor, and save energy and environmental protection.
wipe your body with hot towel
in summer, your body is prone to sweating. Wiping sweat in time can promote skin ventilation, but you must use hot towel to avoid irritation to capillaries and adapt to the cooling law of human body.
