an acute pathological state of humans and animals caused by a disturbance of brain functions as a result of the direct action of the sun’s rays on the head. In humans, structural and functional changes occur in the subcortical and truncal parts of the brain, which regulate respiration, blood circulation, temperature balance, and the level of wake fulness and sleep. The changes are manifested by headache, vomiting, lethargy, an increase in body temperature (sometimes higher than 40°C), convulsions, agitation, and disturbances of the pulse and respiration. In severe cases coma develops. First aid includes moving the sunstroke victim to shade and cooling him with cold compresses and wet packs. In severe cases artificial respiration is administered.
