First of all, outdoor activities should be minimized from 10:00 a.m. to 3:00 p.m. Drink plenty of warm water, umeboshi juice, or mung beans and barley to help cool down. Also, eat some seasonal fruits, such as watermelon, to replenish water. If dizziness, nausea, vomiting and other discomforts suddenly occur during outdoor activities, you should immediately go to a shady place to rest. If you have fever symptoms, you should go to a medical institution in time.
The next step is to move to the shade and douse your entire body with water. Water has a greater ability to carry away body heat than air, and can effectively lower the temperature. Then watch carefully for spontaneous breathing and heartbeat, and if not, perform CPR. The most important thing is to dial 120. 30 minutes is the most critical time for a heatstroke victim to be rescued, otherwise the mortality rate is very high. If you come across someone who is unconscious from heat stroke, every minute counts.
Again, drink more water, it's hot, don't wait until you're thirsty, drink small amounts of water several times. For those who work outdoors, it is recommended to add 0.5 to 1 liter of salty drinks every hour and 6 to 8 liters of water per day. If you don't know how to add salt, you can refer to ? Mustard with mineral water? ,? electrolyte effervescent tablets with mineral water? , oral rehydration salts and other sodium-containing beverages. Eat more high protein, high vitamin food, eat more fruits and vegetables, enhance the body's immunity; eat less high oil and high fat food, eat as light as possible.
It is important to realize that pyrexia is actually a form of heat stroke, a severe form of heat stroke. Heavy physical laborers, the elderly and infirm or people with chronic diseases, and infants and young children in high-temperature and high-humidity environments are high-risk groups for heat stroke. Heat stroke does not occur suddenly. Symptoms such as aura heat stroke and mild heat stroke can occur before heat stroke develops into heat stroke. If you experience mild symptoms of heat stroke, so before you can take some cooling measures to prevent heat stroke from developing further. The mortality rate of heatstroke can be up to 70% to 80%, mainly due to the body's thermoregulatory dysfunction, and accompanied by part of the functional damage of the nervous system.
