Heat exhaustion is brought about by a rise in the core body temperature, usually with dehydration. It is vital to recognize the condition early and seek prompt treatment. If not treated, it can progress to heat stroke.
Once the internal temperature in the body increases, the normal response is to sweat and cooled by evaporation. In case the humidity level is too high in which sweat could not evaporate or the individual is already dehydrated, the internal temperature could not be cooled fast enough and the core temperature increases.
What are the causes?
Any one is at risk for heat exhaustion especially if in a warm environment. Those who are at higher risk include:
- Elderly
- Infants and young children
- Obese individuals
- Individuals who work or exercises under the heat
- Those who have high blood pressure
What are the indications?
- Dizziness or fainting
- Weakness
Transfer the individual to a cool place, preferably with air-conditioning. - Headache
- Excessive sweating
- Warm, pale, moist skin
- Nausea and vomiting
Management of heat exhaustion
If an individual is suspected with the signs of heat exhaustion, some of the self-care measures that must be started includes:
- Transfer the individual to a cool place, preferably with air-conditioning.
- Provide the individual with cool beverages to drink to cool down the body internally. An electrolyte-replacement sports beverage is a good option if the individual has been sweating.
- Wear lightweight clothes that allows perspiration to evaporate
- Sponge the individual with cool water.
In case the symptoms of heat exhaustion seem to worsen or last longer than an hour, seek medical care or bring the individual to the nearest emergency department.
