Heatstroke, commonly known as sunstroke, is defined as a body temperature above the normal daily range of 36–37.5°C. It usually results from a disorder in the body’s temperature control mechanisms. The body’s heat comes from ongoing metabolic processes and heat absorbed from the environment. If the temperature rises, the body fights it by widening the blood vessels and activating the sweating system.
When body temperature rises, signs such as rapid breathing, palpitations and an increased heart rate begin to appear. In particular, when the temperature rises above 42°C, many systems in the human body can no longer function. Heatstroke usually affects people with cardiovascular disease, individuals with neurological and psychiatric illnesses/disorders and people with obesity. People aged 70 and over are more seriously affected.

How should you help a person with heatstroke?
The person should be moved to a cool place out of direct sunlight, their consciousness should be checked by asking simple questions, and their pulse (and, if possible, blood pressure) should be checked. The person should be transferred to the nearest healthcare facility to be evaluated by a physician. If emergency medical services have been called, the person should be kept in a cool place until the team arrives, and their consciousness, breathing and circulation should be checked frequently. Finding out from relatives whether the person has a chronic illness will also save time.
