- Hot, sunny, humid weather
- Physical exertion, especially in hot, humid weather
- Due to impaired thermoregulation, elderly people and infants can get serious heat illness even at rest, if the weather outside is hot and humid, and they are not getting enough cool air.
- Some drugs, such as diuretics, antihistamines, beta-blockers, alcohol, ecstasy, and amphetamines can cause an increase in the risk of heat exhaustion.
Signs and symptoms
First aid for heat exhaustion includes:
- Moving the person to a cool place
- Having the patient take off extra layers of clothes
- Cooling the patient down by fanning them and/or putting wet towels on their body
- Having them lie down and put their feet up if they are feeling dizzy
- Having them drink water or "sports drinks" unless they are unconscious, too disoriented to drink, or vomiting
- Turning the patient on their side if they are vomiting
If left untreated, heat exhaustion may progress to heat stroke.
