What are the ways to prevent heatstroke during outdoor activities?

Travel to avoid the scorching sun

Remember to prepare sun protection equipment when going out in summer. It is best not to walk in the scorching sun between 10 o'clock and 16 o'clock, because the sun is the strongest during this time. , the possibility of heat stroke is 10 times higher than usual! If you must go out at this time, be sure to take protective measures, such as using a parasol, a sun hat, and sunglasses. It is best to apply sunscreen if possible; prepare enough water and drinks. In addition, in the hot summer, heatstroke prevention and cooling medicines, such as Dishui, Longhurendan, Fengyoujing, etc., must be kept at hand for emergency use. When going out, try to use cotton, linen, and silk fabrics as much as possible. Wear less chemical fiber clothing to avoid heat stroke due to inability to dissipate heat in time when you sweat a lot.

The elderly, pregnant women, and people with chronic diseases, especially those with cardiovascular disease, should reduce outdoor activities as much as possible during high temperature seasons.

Don’t wait until you are thirsty before drinking water

Don’t wait until you are thirsty before drinking water, because thirst already means that the body is dehydrated. Ideally, drink 1.5 to 2 liters of water per day, depending on the temperature. When you sweat a lot, you can add some salt water to make up for the salt your body loses due to sweating. In addition, the human body is prone to potassium deficiency in summer, making people feel tired and fatigued. Potassium-containing tea is an excellent summer drink.

Diet

Summer vegetables, such as lettuce, cucumbers, tomatoes, etc., have a higher moisture content; fresh fruits, such as peaches, apricots, watermelons, melons, etc., have a moisture content of 80% % to 90%, can be used to replenish moisture. In addition, dairy products can not only replenish water but also meet the nutritional needs of the body. Secondly, people who cannot avoid working in high-temperature environments should appropriately supplement drinks containing potassium, magnesium and other elements.

Stay adequate sleep

In summer, when the days are long and the nights are short, the temperature is high, the human body's metabolism is strong, the consumption is high, and it is easy to feel tired. Adequate sleep can relax the brain and body systems, which is not only conducive to work and study, but also a measure to prevent heatstroke. The best time to go to bed 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 outlet or electric fan of the air conditioner when sleeping to avoid suffering from air conditioning disease and heat cold.

How to prevent heatstroke? What should I do if I have heatstroke?

Heat stroke is a disorder of body temperature regulation under the influence of high temperature, often caused by exposure to the scorching sun or heavy physical labor in a high-temperature environment.

Severe heat stroke can be further divided into:

Heat stroke and high fever, that is, a large amount of heat accumulation in the body. People with heat stroke may experience drowsiness, coma, flushed complexion, dry and hot skin, no sweat, shortness of breath, increased heart rate, decreased blood pressure, high fever, and body temperature can exceed 40 degrees.

Heat exhaustion means that there is not a lot of heat accumulated in the body. People suffering from heat stroke may have pale complexion, clammy skin, weak pulse, shallow and fast breathing, syncope, coma, and drop in blood pressure.

Heat stroke spasm:

It is not directly related to high temperature, but occurs after strenuous labor and exercise. Due to heavy sweating and only drinking water without replenishing salt, blood sodium and chloride levels will increase. Chemicals decrease, and blood potassium may also decrease, causing paroxysmal painful muscle spasms (commonly known as cramps), thirst, and oliguria, but the body temperature is normal.
