Summer health care: 10 ways to use heat to prevent heatstroke and cool down

In the hot summer, the human body sweats a lot and consumes a lot of physical energy. If you are not careful, it will cause symptoms such as dizziness and sore throat. So, what methods should be used to prevent heatstroke and cool down in summer? Let us take a look at how to "heat with heat" and cool down.

Drink hot tea

Cold drinks can only temporarily relieve heat, but cannot relieve heat and thirst permanently. Do not consume too much, otherwise the temperature of the stomach and intestines will drop, causing irregular contractions and inducing abdominal pain, diarrhea, etc. Drinking hot tea can stimulate the general dilation of capillaries, which can significantly lower body temperature. Studies have shown that drinking a cup of hot tea for 9 minutes can lower body temperature by 1℃ to 2℃, and the temperature reduction can be maintained for more than 15 minutes.

Therefore, drinking hot tea in the summer is a simple and easy way to cool down. You can drink tea leaves alone, or you can drink fruit tea, scented tea, etc. You can also wash 10 grams of dried orange peel, tear it into small pieces, put it in a cup with 5 grams of green tea, add boiling water, cover it and soak it for about 10 minutes, remove the residue, add a piece of rock sugar and drink it. Koreans have the habit of eating ginseng chicken soup as a tonic during the dog days of summer, which is also an effective way to "control heat with heat".

Take a hot bath

Taking a cold shower in the summer will cause the skin capillaries to constrict, making you feel hotter afterwards. Although taking a hot bath will cause more sweating, it can dilate capillaries, help the body dissipate heat, promote metabolism, speed up the removal of metabolic products such as lactic acid, and eliminate body fatigue. The water temperature is generally controlled at around 30℃.

Hot water foot bath

Soaking your feet in hot water can open the pores all over your body, which is beneficial for heat dissipation. Therefore, insisting on soaking your feet in hot water in the summer can promote perspiration, enhance the function of sweat glands, and improve heat resistance. Before going to bed every night, you can soak your feet in warm water at about 40℃ (the water covers the ankle joints) for 15 to 20 minutes each time (you can add hot water to maintain the water temperature during this period), and it is best to feel a slight sweat.

Eat hot food

Many people think that when the weather is hot, some food can be eaten without heating. This view is wrong. Hot and humid environments are prone to breeding bacteria and other pathogenic microorganisms. Heating can disinfect and sterilize, protecting people's bodies from bacterial invasion. When cooking, you can use some green onions, garlic, ginger and other seasonings to increase body sweating and prevent heatstroke and reduce body temperature.

Exercise and sweating

Appropriate physical exercise can enhance the body's heat tolerance and improve the body's temperature regulation function. It can also strengthen the physical fitness and prevent heat stroke. To avoid heatstroke, summer exercise time can be around six or seven in the evening. Fitness activities include swimming, walking, and Tai Chi. When exercising, wear clothes made of pure cotton, good sweat absorption and good breathability. After exercise, wipe off the sweat on your body and wait until your body temperature returns to normal before using the air conditioner.

Hot compress on navel

Use a hot water bottle or hot towel at a temperature of about 40℃, gently apply it on your navel, remove it after a few minutes, and apply it 1 to 2 times a day. This is one of the methods used by the ancients to treat heatstroke. You can also rub your hands together on an empty stomach every night before going to bed, place your palms together on your navel, and rub them in a counterclockwise direction with small movements, 20 to 30 circles each time.

Warm sweating

Sweating is the body's way of dissipating heat, but due to the widespread use of air conditioning, the sweat glands of people who are in a temperature-stable environment for a long time are almost idle. Even in the summer, when it is the season to sweat, they do not sweat often, which is harmful to their health. In order to adapt to the rhythms of the four seasons and the laws of life, you should sweat when you should.

Ginger has three major effects: sweating and relieving exterior symptoms, warming the middle and stopping vomiting, and detoxification. Drinking ginger soup regularly can induce sweating and relieve heat. You can drink water with shredded ginger every morning, or you can use ginger slices to make black tea. It is not advisable to eat ginger at night.

Clothing should not be too revealing

Don't dress too revealingly. In summer, people wear thinner and thinner clothes, exposing more and more body parts, thinking that this can help cool down. In fact, when the outside temperature is higher than the skin temperature, the skin not only cannot dissipate heat, but will absorb heat from the external environment. If the exposed area of ​​the clothes is too large, heat radiation will easily penetrate the skin, making it even hotter. This is why it feels hotter to be shirtless in summer.

Experts recommend wearing light, breathable, loose clothing in the summer, preferably light-colored. The exposed area should not exceed 25% of the total surface area of ​​the human body. When going out, wear a hat, carry an umbrella, wear sunglasses, and wear long-sleeved clothes to protect your skin.

Heat and air conditioning

Adjust the air conditioner to 25℃ ~ 26℃, which is the most suitable temperature for the human body. It can avoid the discomfort caused by the large temperature difference between indoor and outdoor, and it is energy-saving and environmentally friendly.

Hot towel body

In summer, the body is prone to sweating. Wiping sweat in time can make the skin breathable, but a hot towel must be used to avoid irritation to the capillaries and adapt to the body's cooling rules.
