Sweating, or tropical lichen, can occur when a person has not yet acclimatized to a hot climate. Skin-rubbing clothing against the background of profuse sweating can lead to blockage of sweat glands and unpleasant irritation. Large physical exertion can contribute to the appearance of prickly heat, which is exacerbated by sunburn and eczema.
The dangers of a warm climate, prickly heat, convulsions, overheating of the body, heat or sunstroke, sunburn, eye irritation, dehydration.
Excess sweat cannot evaporate quickly enough, the glands turn out to be closed and the cooling effect of sweating disappears. Consuming more fluids, especially hot ones, in hot climates can increase perspiration and make the situation worse. Take off your clothes, wash your body with cold water and put on dry clothes. Antihistamines help reduce discomfort.
. This can also happen without being in direct sunlight, for example, if a person lies on hot ground without proper ventilation.. Symptoms pallor of face, cold, sweat-covered skin, weak pulse. It is accompanied by dizziness, weakness and possibly convulsions. The victim may experience confusion or unconsciousness.. Treatment: as with cramps.
Heat or sunstroke, symptoms and treatment.

Take off your outer clothing. Cool the body by moisturizing underwear with lukewarm water (cold water will raise the internal temperature of the body).
Do not immerse the patient in water, completely spray him. Then lay in a moist recess, but with a good flow of air. When consciousness returns, give a drink. After the temperature becomes normal, change clothes, provide warmth so that the patient does not freeze. Immersion in cold water is very dangerous, but in exceptional cases, when the risk of death or damage to the brain outweighs the risk of shock from immersion, it can be used after the initial cooling starts.
Slowly immerse the body in water, first the legs, massaging the limbs in order to activate the blood flow to them and help to remove heat from the inside of the body, thereby reducing its internal temperature. Leave the water as soon as the temperature drops, be prepared to dress the patient if it drops too sharply. You may need to cool and warm the patient several times before the temperature stabilizes..
