Heat stroke is the most serious heat-related disorder. Heat stroke results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system. It occurs when the body becomes unable to control its temperature: the body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Heat stroke can kill or cause damage to the brain and other intenal organs if emergency treatment is not given.
Heat stroke is most likely to affect older people who live in apartments or homes lacking air-conditioning or good airflow. Other high-risk groups include people of any age who don't drink enough water, have chronic diseases, or who drink excessive amounts of alcohol. While many people feel sick and faint during heat waves, most of these people are suffering from heat exhaustion, a related condition usually less serious than heat stroke
Symptoms of heat stroke include:
If you suspect that someone has a heat stroke, immediately call 911 or transport the person to a hospital.The patient's condition should be reassessed and stabilized by trained medical personnel. Any delay seeking medical help can be fatal. While waiting for the paramedics: Take immediate action to cool the overheated person. You can cool the patient down with whatever means available :
Things you can do to reduce or prevent Heat Stroke include;
It takes the aged nearly twice the time of younger people to return to core body temperature after exposure to extreme temperatures. Others who are particularly vulnerable to heat stroke ,include infants and children up to four years of age, those who are overweight and people with heart and respiratory problems.
Take precautions against high temperatures to avoid heat-related illnesses. High body temperatures can lead to damage to the brain or other vital organs and even death.
