Sunstroke is a form of heat exhaustion caused by prolonged exposure to the sun for long periods. The temperature of the body increases to 40 ° and, the body can no longer regulate its internal temperature to maintain 37 °. We are talking about hyperthermia.
Cramps, muscle aches, fatigue or great thirst may occur, and also headaches. The skin becomes warm, red and dry as the organism cannot perspire normally. Subsequently, the affected person may suffer from nausea, vomiting, muscle pain, a stiff neck , tightness in the chest, confusion, ringing in the ears, accelerated breathing and heart rhythm, seizures, dizziness and even fainting.
Untreated heat stroke can cause neurological disturbances, kidney or heart problems and comas. Above 40.5 ° the risk is deadly.
Sunstroke particularly affects children and the elderly.
Heat stroke can also happen because a particular area is too exposed to sun (car in direct sunlight, attic rooms in midsummer), intense physical activity, or simply a heat wave.
NB: Alcohol is a risk factor because it can prevent the body from properly regulating its temperature.
Urgent action is required to reduce body temperature as quickly as possible. The person should immediately be moved to a shady place, cooled down and hydrated before assistance is sought.
