Heatstroke Symptoms
Heatstroke is the most severe heat illness as it could be life threatening. It is a dangerous condition that often results from heavy activates (e.g. workout) in hot or humid environments along with little fluid intake, causing the internal temperature to rise. It is potentially life-threatening because the body's normal means for dealing with heat stress, such as temperature control, are lost.
Heatstroke risk factors:
- Heatstroke poses a greater risk to young children, older adults, overweight people and people with a weakened ability to sweat.
- Other risk factors include dehydration, alcohol use, cardiovascular disease and some medications.
Heatstroke symptoms include the following:
- Noticeably elevated body temperature (more than 40 C).
- Mental changes e.g. personality changes, confusion, irritability, or unconsciousness.
- Fatigue.
- Skin hot and dry, unless heatstroke resulted from exertion, in that case the skin may be moist.
- Fast heartbeat.
- Rapid and shallow breathing.
- Blood pressure is too high or too low.
- Sweating stops.
- Feeling dizzy or lightheaded.
- Headache.
- Nausea.
What to do when suspecting heatstroke?
- If achievable, move the person out of the sun and into an air-conditioned space. Otherwise, try to provide them with as much shade as possible.
- Call for emergency medical assistance .
- If possible, carefully cool the person's body by covering him or her with damp sheets, ice packs or by spraying with cool water.
- Fan air onto the person.
- If able, slowly have the person drink cool water or juice.
