Cause
In the hot sun or high temperature environment, the body's heat cannot be dissipated in time, causing body temperature regulation obstacles;
Excessive sweating causes dehydration and salt loss, blood concentration, muscular blood vessel expansion and blood pressure drop, and insufficient blood supply to the brain;
In the event of high temperature and high humidity, excessive fatigue, coupled with increased heat production during exercise, evaporation is affected, resulting in increased body temperature, causing dehydration and imbalance of salt metabolism.
Symptoms appear
Feeling dizzy, headache, rapid heartbeat, nausea, vomiting, excessive sweating, low blood pressure, diarrhea, dry skin and other symptoms. In severe cases, it can suddenly faint, convulsions, and the body temperature rises sharply. The anal temperature can reach more than 39.5, convulsions, and even life-threatening.
Approach
Lift off the patient from the high temperature environment to a cool and ventilated place;
Elevate the head and loosen the extra clothes for the patient;
Carry out cold compress on the head and neck, ventilate and dissipate heat;
Spray water on the core torso of the body;
If the injury is thirsty, add water and electrolyte at the same time;
If the history of injury is that the electrolyte concentration is reduced after drinking a lot of water, you should restrict drinking water and supplement food properly;
If severe breathing, vomiting, irritability, convulsions and other severe cases occur, they should be sent to the hospital for treatment.
Precaution
Plan and prepare in advance;
Reasonably arrange activity time, try to avoid the noon hot time;
Ensure adequate sleep and a happy mood before the trip;
Participate in activities, wear clothes that fit loosely and match reasonably;
When resting, choose a cool, ventilated and sun-proof place, unbutton the sleeves and neckline buttons, pull up the trouser legs, and quickly dissipate heat;
Pay attention to the rhythm of walking and avoid excessive fatigue;
The principle of "replenishing water with a small amount and taking the initiative" is a scientific and reasonable way to replenish water and salty food.
