Prepare enough water to drink in time, and control the water consumption at 150-200ml each time. Drink warm water instead of ice water.

According to the temperature, the average person drinks 1.5-2 liters of water every day, while high-temperature workers drink 3-5 liters of water every day and eat fruits and fresh vegetables. Appropriate intake of salt to supplement electrolyte loss caused by excessive sweating. When sweating a lot, you can add some salt water appropriately to make up for the salt lost by sweating.

In addition, the human body is prone to potassium deficiency in summer, which makes people feel tired and weak. Potassium tea is an excellent summer drink. Pay attention to avoid drinking water containing caffeine, alcohol and a lot of sugar.

2. Heat dissipation in time

Take more baths or wipe your skin with a wet towel. When the weather is too hot, you should shower your head and neck to let the water evaporate to help dissipate heat. It should be noted that when you are sweating all over, don't take a bath with cold water immediately. You should dry your sweat first, take a rest and then take a bath with warm water.

3, a reasonable diet

Eat more fruits and vegetables with high water content in summer, such as lettuce, cucumber and tomato. Peaches, apricots, watermelons, melons, etc. It has a water content of 80% to 90% and can be used to replenish water; Dairy products can not only replenish water, but also meet the nutritional needs of the body.

In addition, people who work in high temperature environment should properly supplement drinks containing potassium, magnesium and other elements.

It is necessary to raise the awareness of preventing stroke. Eat less and eat more, avoid being too full and greasy, lest the gastrointestinal tract compete with the brain for blood flow when digesting food, and increase the probability of ischemic stroke. Any patient with cardiovascular and cerebrovascular diseases and diabetes should insist on taking medicine.

Step 4 get enough sleep

Adequate sleep can relax the brain and body system, which is not only beneficial to work and study, but also can prevent heatstroke.

The best time to sleep is from 22: 00 to 23: 00, and the best time to get up is from 5: 30 to 6: 30. Be careful not to lie under the air conditioning outlet and electric fan when sleeping, so as not to get air conditioning disease and catch a cold.

5, equipped with drugs

Personnel engaged in outdoor activities or high-temperature operations should carry heatstroke prevention drugs such as ten drops of water, Ren Dan, Huoxiang Zhengqi Water or Huoxiang Zhengqi Pill with them, or put them in nearby workplaces for use at any time to prevent heatstroke.

6. Try to avoid high temperature periods when going out in summer, try to avoid or reduce outdoor activities during the day, especially 10 to 16, and don't go out to exercise and work in the scorching sun.

If you must go out at this time, you must take good protection, such as umbrella, hat and sunglasses. If possible, it is best to apply sunscreen to prevent sunburn.

When working outdoors, you should wear straw hats, light-colored clothes, drinking water and heatstroke prevention drugs. Try to choose cotton and linen clothes with light color and good air permeability, and wear less chemical fiber clothes.

Misunderstanding of heatstroke prevention:

First, over-reliance on air conditioning

After all, air conditioning is not a natural state. It can make the air flow and vibrate frequently, and the result is just like noise, which will damage people's nervous function. In addition, indoor air is recycled, and after repeated filtration, the negative ions in the air are obviously reduced, and there are too many cations, which affects the normal physiological activities of the human body.

Second, the electric fan blows directly on the human body.

Some people like to enjoy the cool air, and often blow directly at the electric fan, which will cause a series of symptoms such as sneezing, runny nose, fatigue, headache, dizziness, insomnia, shoulder pain, loss of appetite and so on. This is called "Fan Disease".

Third, wash your feet with cold water to cool down.

Some people like to wash their feet with cold water, which is not desirable. Because people's feet are the distal parts of blood vessel branches, the skin temperature of the soles of the feet is the lowest in the whole body, and it is easy to catch cold; Furthermore, the fat layer of the feet is thin and the heat preservation is poor. If you often wash your feet with cold water, you will get cold further, which will cause a series of pathologies throughout the body through vascular conduction and eventually lead to various diseases.

Fourth, take a cold bath when sweating.

The temperature is high in summer, and the body generates more heat during exercise. It is an important way to dissipate heat through sweat and skin blood vessels. At the end of labor or exercise, the human body is still in a state of vigorous metabolism, increased heat production and vasodilation of the skin.

At this time, if you take a cold bath immediately, the skin will be stimulated by cold, and the skin blood vessels will contract through nerve reflex. As a result, the body heat will be blocked and the body temperature will rise instead.
