What to do if you suspect someone has symptoms
Print Edition
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.
The hallmark symptom of heat stroke is a core body temperature above 40 degrees Celsius. But fainting may be the first sign.
Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness.
Heat stroke is the most serious form of heat injury. It can kill or cause damage to the brain and other internal organs and mainly affects people over the age of 50.
If you suspect someone has heat stroke, call 120 or take the person to hospital. Any delay in seeking medical help can be fatal.
While waiting for paramedics to arrive, initiate first aid. Move the person to an air-conditioned environment or a cool, shady area and remove any unnecessary clothing. Fan air over the patient, while wetting the skin with water from a sponge.
On hot days, if you must go outdoors, you can prevent heat stroke by wearing lightweight, loose-fitting clothing and a wide-brimmed hat. Use sunscreen with a sun protection factor of 30 or more. Drink extra fluids.
To prevent dehydration, it’s recommended to drink at least eight glasses of water, fruit juice or vegetable juice per day.
