It's too hot, how to prevent heatstroke?

Here are some common sense of life for your reference. Please take measures to prevent heatstroke and cool down, and pay attention to your health.

First, replenish water in time but drink less drinks. Juice, cola, sprite, soda and other drinks contain more saccharin and electrolyte. Drinking too much will cause bad stimulation to the gastrointestinal tract and affect digestion and appetite. So drink more boiled water or light salt (sugar) boiled water in summer.

Second, it is not advisable to binge drink after being thirsty. After sweating a lot in labor and sports, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be supplemented appropriately, because after sweating a lot, too much salt is lost in the human body, accounting for about 0.5% of sweat. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder.

3. The strongest time of solar short-wave radiation is around 10-15. Try to avoid going out during this time, and apply some sunscreen skin care products to your skin. It is best to wear light clothes in summer.

Fourth, it is not advisable to drink too much. In summer, human body is easily affected by temperature, and excessive damp heat is the cause of skin sores, carbuncle and toxic swelling. If you drink a lot of white wine, it will contribute to dryness and dampness, which is tantamount to adding fuel to the fire.

Fifth, the diet should not be too light. In summer, people have long activities, sweat a lot and consume a lot. They should eat more nutritious foods such as chicken, duck, lean meat and fish eggs to meet the metabolic needs of the human body.

Sixth, the nap time should not be too long. If the nap time is too long, the central nervous system will deepen the inhibition, the cerebral blood flow will be relatively reduced, and the metabolic process will slow down, leading to discomfort after waking up and more sleepiness.

7. Avoid "rapid cooling" after heating. In hot summer, when people go out or come back from work, they like to either turn on the electric fan or take a cold bath immediately, which will make the pores of the whole body close quickly, but the heat in the body is difficult to dissipate, and it will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which makes people dizzy.

Eight, air conditioning indoor and outdoor temperature difference should not be too big. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees.

Nine, it is not appropriate to wear metal jewelry. Some metals in metal ornaments are stained with sweat, and the skin will be red or itchy when worn, which may easily lead to contact dermatitis.

In order to prevent the occurrence of heatstroke, in addition to avoiding going out from the morning to 2 pm in the strongest sunshine 10, necessary protective measures should be taken: ① keep indoor ventilation and lower the room temperature, at least with electric fans; ② Working hours at high temperature should not be too long, and should not exceed 8 hours every day; (3) Reduce labor intensity, prepare heatstroke prevention and cooling drinks, and supplement brackish boiled water or salty drinks as much as possible; Ensure adequate sleep and eat more nutritious fruits and vegetables. ⑤ Try to penetrate the air-cooled cotton-padded jacket.

To prevent heatstroke, we must pay attention to diet again. What should we eat? People's diet in midsummer is very important, because people work in a hot environment, and obvious changes have taken place in body temperature regulation, water and salt metabolism, circulation, digestion, nervous system, endocrine system and urinary system, which will lead to an increase in nutrient consumption and a large amount of water and nutrients will be lost due to sweating. In summer, people's loss of appetite will also limit the absorption of nutrients. Expert advice: pay attention to supplement some nutrients. To supplement enough protein, fish, meat, eggs, milk and beans are better.

Vitamin supplement: fresh vegetables and fruits, such as tomatoes, watermelons, bayberry, melons, peaches and plums. , especially rich in vitamin C; Vitamin B is abundant in cereals, beans, animal livers, lean meat and eggs.

To supplement water and inorganic salts: you can eat foods with high potassium content, such as fruits, vegetables, beans or bean products, kelp, eggs and so on. Eat more foods that clear away heat and promote diuresis: watermelon, bitter gourd, peach, dark plum, strawberry, tomato, cucumber, mung bean and so on. In addition, drinking porridge in summer is also of great benefit. Red bean porridge has the function of tonifying kidney and eliminating edema, and people with poor renal function had better eat more. Broad bean porridge is good for chronic edema and nephritis. Lotus leaf porridge can relieve summer heat, clear stomach and moisten intestines, quench thirst and detoxify. Lotus porridge can strengthen the spleen and replenish qi, and is good for diarrhea, insomnia, nocturnal emission and leucorrhea. Lily porridge can moisten the lungs and relieve cough, nourish the heart and soothe the nerves, and is suitable for the elderly with insufficient lung yin. Winter melon porridge has the effects of diuresis, detumescence, quenching thirst, promoting fluid production and lowering blood pressure. Auricularia auricula porridge can promote fluid production and moisten lung, nourish yin and moisten lung, and can treat hypertension and chronic bronchitis. Astragalus porridge can treat edema caused by spleen deficiency.

Many people turn on the air conditioner when it is hot, so how to avoid air conditioning disease? -To prevent air-conditioning diseases, it is necessary to open the window frequently for ventilation, and it is best to open it 1-3 hours before closing it. It is necessary to use natural wind to reduce indoor temperature, and it is best to use negative ion generator; It is best to set the room temperature at about 25-27 degrees Celsius, and the indoor and outdoor temperature difference should not exceed 7 degrees Celsius, otherwise entering the room after sweating will increase the burden on the thermoregulation center and cause neuromodulation disorders; The air-conditioned room should be kept clean and hygienic, and it is best to clean the air-conditioning filter once every half month; Don't put your desk where the cold wind blows directly. If you sit for a long time, you should add clothes properly and cover your knees with a towel for protection. After coming home from work, take a hot bath first, massage yourself, and then exercise properly to enhance your resistance.

Beware of air-conditioning diseases in the car-air-conditioned car drivers should also pay attention to prevent air-conditioning diseases. When using the car air conditioner, don't set the temperature too low, and the temperature difference between the inside and outside of the car is best within 10 degrees Celsius; Don't smoke in the air-conditioned car, or turn the air-conditioning ventilation control switch to "exhaust"; Don't sleep in a parked car with air conditioning. Poor ventilation in the car, carbon monoxide emitted by the engine leaks into the car, which will make people poisoned. Cars parked under the scorching sun had better not use the air conditioner immediately, but should open the window to let the hot air out, and then close the window and turn on the air conditioner after the temperature inside the car drops.

Wear light-colored clothes when going out in summer, and try to avoid going out when the sun is strongest from 10 to 2 pm, but it is good to bask in the rising sun in the morning. In summer, strenuous exercise such as mountain climbing and long-distance running is not recommended. You can choose swimming (but at night, you need to use hot water of about 45 degrees, and after washing, your sweat pores are open, which is easy to emit heat in your body) and jogging early: let your body adapt to the rising temperature during the day, and take a walk at night to eliminate the fatigue of the day.
