Heatstroke comes out after a long sunlight exposure. The first sign of trouble is a sudden and general indisposition followed by headache, dizziness, nausea. Body temperature rises, skin looks dry and very red.
What to do
The first thing to do is bring the affected person to a cool shady, make her lie down on the ground holding her legs up compared to the rest of the body. Dip a sheet or a large towel in cold water and then wrap the person to make them feel an immediate well-being. If it is possible, fill a tub with cold water and then stretch the hit person. It is wise to keep an ice-bag over his head. If after half an hour of “cooling treatment”, body temperature does not drop, an ambulance has to be called.
