1. Premonitory heat stroke

Symptoms: headache, dizziness, fatigue, nausea, lack of concentration, rapid heartbeat, flushed skin but no cold sweat.

At this time, the body has actually sounded the alarm, but many people mistakenly think that it is "too long in the sun" or "hungry" and continue to move, resulting in a more serious heat stroke step by step.

2. Mild heat stroke

Symptoms: increased body temperature (above 38℃), heavy sweating, flushed face, rapid pulse, muscle cramps, and may be accompanied by vomiting and confusion.

At this time, it is necessary to stop activities immediately and take emergency measures, otherwise it may develop into severe heat stroke.

3. Severe heat stroke (heat stroke)

Symptoms: body temperature quickly rises to above 40℃, confusion, coma, convulsions, dry and hot skin without sweat, and even shock.

This is the most dangerous stage, with a very high mortality rate. It must be sent to the doctor immediately, otherwise the consequences will be disastrous.

2. Who is more likely to get heat stroke? You may be on the "high-risk list"

Not everyone has the same probability of heat stroke. Some people are more likely to be "infected" due to their physical characteristics or environmental reasons.

Outdoor workers: sanitation workers, construction workers, takeaway riders, etc. work in high temperatures all year round and are the hardest hit by heat stroke.

Children and the elderly: The body temperature regulation center is not sensitive enough, they are prone to heat stroke and recover slowly.

Chronic disease patients: such as those with hypertension, diabetes, and heart disease, have poor adaptability to high temperature environments.

Excessive exercisers: Long-term running and cycling under the sun in summer are prone to dehydration and electrolyte disorders.

In addition, being in a hot and unventilated environment for a long time, such as a hot bus or a car without air conditioning, is also an invisible risk place for heat stroke.

Move the patient to a cool, ventilated, air-conditioned room or at least a place with a fan, so that the body can start to cool down naturally.

Step 2: Undress and give priority to heat dissipation

Loosen or take off heavy clothes, wipe the body with a wet towel if necessary, or use an electric fan to help dissipate heat.

Step 3: Physical cooling and control body temperature

You can use a cold towel to apply to the forehead, armpits, neck, groin and other large blood vessel distribution areas, or you can rub alcohol on the limbs to help cool down (be careful to avoid large-area skin irritation).

Step 4: Rehydrate and replenish salt to restore physical strength
