Sunstroke and heat stroke
Sunstroke and heat stroke can kill. They occur when the natural body temperature regulating system fails because of extended exposure to high environmental temperatures.
Heat stroke is often combined with periods of high physical exertion. The patient experiences a sharp increase in body temperature and an associated fever, which can cause permanent damage to internal organs, resulting in death if not treated immediately.
Heat stroke is often seen when somebody who is not acclimatised enters a particularly hot or humid environment, or performs strenuous physical activity in a hot and humid environment. Young children and the elderly arc at most risk, though in the right circumstances anyone can become a victim.
