What are the tips for heatstroke prevention in hot weather?

With global warming, summer in many parts of the world becomes hotter than before, especially when you need to go out at noon in summer, you must do a good job of sun protection, otherwise you may get sunburn and heatstroke. So what are the tricks for heatstroke prevention and cooling in hot weather? What are the wrong methods for heatstroke prevention in hot weather?

1, a coup to prevent heatstroke in hot weather

In fact, heatstroke can be avoided as long as preventive work is done.

1, don't wait for thirst to drink water.

To prevent heatstroke, we must first develop the habit of drinking water actively, and don't wait for thirst before drinking water. Because when people feel thirsty, the body is already in a state of water shortage. After getting up in the morning, there are four "best drinking times" around 10 in the morning, 3-4 pm and before going to bed at night, and you should drink 1-2 cups of boiled water each time. When sweating a lot, you can add some salt water appropriately to make up for the salt lost by sweating.

2, impatience is easy to get heatstroke, and the heart is calm and naturally cool.

High temperature and high fever, easy to get angry, often feel upset, loss of appetite, impatience and anxiety. This is a typical symptom of "emotional heatstroke". Therefore, the hotter the weather, the more you need to calm down. Calm, natural and cool, help to reduce their mental heat, reduce the negative impact of weather on the body. In addition, finding the weakness of your personality in time, being calm, tolerant, less angry and keeping an open mind will help prevent "emotional heatstroke".

3, often drink soup to cool off the heat

The more people sweat, the more body fluids they consume. Drinking soup can not only replenish water for the body in time, but also help digestion and absorption. Mung bean sour plum soup, hawthorn soup, honeysuckle soup, etc. It is a common summer soup on weekdays.

Step 4 get enough sleep

In summer, the days are long and the nights are short, so it is easy to feel tired. If you don't get enough sleep, it will easily lead to heatstroke. Adequate sleep can relax the brain and body system, which is not only beneficial to work and study, but also a good measure to prevent heatstroke.

5, pay attention to avoid be affected with damp.

Summer heatstroke should pay more attention to avoid humidity, especially in rainy areas in the south. The weather is hot and humid. Wear a straw hat or parasol when going out to keep out the direct sunlight. Clothes should be wide and cool, sweat for a long time, and wet clothes and undershirts should be frequently changed and washed to prevent external moisture from invading. Don't wear tight and airtight clothes to show your figure, so as not to lose heat in time when you sweat a lot.

Step 6 drink warm tea

Warm tea can reduce the skin temperature 1-2 degrees, while cold drinks can only cool the mouth. Drinking tea will make people feel cool and comfortable, and thirst will disappear completely. Moreover, people who drink cold drinks are uncomfortable and thirsty. It is more effective for high-temperature workers to prevent heatstroke if they can add some salt to warm tea to make up for the salt lost due to excessive sweating.

7. Room ventilation

The most important thing to prevent heatstroke is indoor ventilation. Don't always close the doors and windows. In the morning or evening, it is best to open the window for ventilation. When it is hot at noon, you can turn on the air conditioner or electric fan, and try to lower the room temperature to about 26℃ to avoid heatstroke. When turning on the air conditioner, be careful not to let the temperature difference between indoor and outdoor be too large, and don't let the children stay in the air-conditioned environment for a long time.

8. Eat more fruits and vegetables.

Fruit juice is sweet, which can not only quench thirst, but also clear away heat and relieve summer heat. Watermelon tastes sweet and juicy, which is definitely the first choice for clearing away heat and quenching thirst. Wax gourd and cucumber are eaten raw after washing, or made into juice, which has a good effect of clearing away heat and relieving summer heat. Kiwi contains a lot of vitamin C, which has a very good effect of clearing away heat and relieving summer heat. It is a fruit and drink often selected by high temperature and field workers.

The weather is hot and humid, and people like to eat light, delicious and non-greasy food. Vegetables have this characteristic and are rich in vitamins and minerals. So try to eat more green vegetables, such as beans, melons, Chinese cabbage, parsley and so on. You can eat it cold and raw, or you can fry it with a little shredded lean meat.

9. Travel to avoid the scorching sun

Remember to prepare sunscreen equipment when you go out in summer. 10- 16 It is best not to walk in the scorching sun, because the sun is strongest at this time, and the possibility of heatstroke is 10 times as usual. If you must go out at this time, you must take good protection, such as wearing a sunshade, a sun hat, sunglasses, and sunscreen if possible. Also prepare plenty of water and drinks.

In addition, in the hot summer, you can take heatstroke prevention and cooling drugs, such as ten drops of water, Ren Dan, essential oil, etc. It must be kept at hand in case of emergency. When going out, try to choose cotton, linen and silk fabrics, and wear less chemical fiber clothing to avoid heat dissipation in time when sweating a lot, resulting in heatstroke. The elderly, pregnant women, patients with chronic diseases, especially those with cardiovascular diseases, should try to reduce outdoor activities in the hot season.

2. Wrong measures for heatstroke prevention and cooling in hot weather

1, sunscreen is too thick or coated with cooling oil.

Many people mistakenly think that sunscreen can protect themselves from the sun and naturally prevent heatstroke, so whenever they go out, they should apply a thick layer or cool oil all over their bodies to cool down. In fact, these practices can not only prevent heatstroke, but will lead to heatstroke. Thick sunscreen covering the skin will affect sweat discharge, which will naturally lead to slow heat dissipation. Similarly, covering the whole body with cool oil will also reduce the discharge of sweat because of a cool feeling.

2. Pour water in a sealed room to cool down.

Many people like to splash water indoors to cool down. In fact, the method of splashing water does make water vapor evaporate and take away some heat. So when the water is poured, the indoor temperature will drop temporarily. However, if the indoor ventilation is not good, the air is not circulated, and water is poured on the ground, it is difficult for the evaporated water vapor to spread out and stay in the air, which will increase the indoor air humidity. Moreover, the indoor temperature will rise again later. At this time, people will feel indoors. In addition, due to the high temperature in summer and the rapid evaporation of water, indoor bacteria and dust enter the air with water vapor, making the air more turbid than before splashing water.

Therefore, it is not advisable to splash water in a closed room in summer to cool down. The correct way should be to open the doors and windows to let the air circulate when pouring the right amount of water indoors, and it is best to turn on the fan to speed up the air circulation. Alternatively, you can humidify and cool the air by putting water in the washbasin, but it should be noted that the water in the washbasin should be changed every day.

3. Enjoy the cool under the big tree at night.

Many people, whether rural villagers or urban residents, are used to enjoying the cool under trees in midsummer nights. In fact, this practice is also undesirable.

In the sultry summer, the temperature under the tree is indeed lower than that in the open space during the day by more than 3℃, because the canopy can reflect and absorb part of the heat in the atmosphere, and the leaves can absorb carbon dioxide and release oxygen through photosynthesis. Therefore, enjoying the cool during the day or walking in the shade will make people feel cool and comfortable. But at night, the situation is completely different, and it is often sultry under the tree than in an empty place. The reason is that after the sun goes down, the ground heat dissipation under the tree is blocked by the crown, which leads to slow heat dissipation and more carbon dioxide. Therefore, in the midsummer night, people should not enjoy the cool under the tree, but should enjoy the cool in an open place.

Finally, I would like to remind everyone that once heatstroke occurs, the patient should be carried to a cool and ventilated place, lie down and rest, unbutton the patient's clothes, apply a cold towel to the patient's head and neck, and then be sent to a nearby hospital for treatment.
