Quick Answer
To treat heat stroke, quickly move the affected person to a shaded or air-conditioned area, remove excess clothing, and cool the body with cool water or a fan. This can help lower the body temperature, which is essential for recovery. If you're in a remote area, use any available resources to cool the person as quickly as possible.
Recognizing Heat Stroke Symptoms
Heat stroke can be life-threatening and requires immediate attention. Symptoms include a body temperature of 103°F (39.4°C) or higher, confusion or altered mental state, slurred speech, seizures, and loss of consciousness. If you suspect someone has heat stroke, do not delay in seeking medical help.
Cooling the Affected Person
To lower the person’s body temperature, use cool water to cool the skin. Wet the person’s clothes and apply ice packs or cold compresses to the armpits, neck, and groin area. You can also use a fan to circulate air and help evaporate sweat. The American Red Cross recommends cooling the body to a temperature between 94°F (34.4°C) and 99°F (37.2°C) as quickly and safely as possible.
Transporting and Monitoring the Person
Once the person’s body temperature has been lowered, transport them to a medical facility immediately. Monitor their vital signs, including their temperature, pulse, and breathing rate. If they become unresponsive or show signs of cardiac arrest, begin CPR (cardiopulmonary resuscitation) and continue until medical help arrives. If the person starts showing signs of cardiac arrest, CPR should be initiated immediately.
