Heat exhaustion is a more serious condition than heat cramps and occurs because of prolonged exposure to heat, which is often accompanied with physical exertion. This combination leads to excessive sweating and could eventually lead to heat exhaustion.
What is the physiological explanation of heat exhaustion?
Basically, there is a good deal of fluid lost, due to sweating. In addition, in an attempt to cool the body down, blood pools in the blood vessels near the skin. This changes circulation and takes blood away from vital organs.
What are the signs/symptoms of heat exhaustion?
- cold, clammy skin (telltale sign used to distinguish from heatstroke)
- dilated pupils
- excessive sweating
- dizziness, blurred vision, headache or cramps
- signs of shock: weak, rapid pulse; rapid, shallow breathing; vomiting; unconsciousness
What should I do to treat someone with heat exhaustion?
If patient is conscious
1) Give them water to drink and have them drink as much as they can. If they vomit, seek medical attention right away.
2) Have them rest in a cool, dry place.
3) Place them flat on their back with their feet elevated.
4) Remove excessive clothing and loosen anything that is tight around the neck or waist.
If patient is unconscious
1) Seek medical attention immediately.
While heat exhaustion is not as serious as heat stroke, it is not to be taken lightly. Try the treatment I suggested above and if that does not help, don’t delay seeking medical help!
