WebMD explains the symptoms and treatment of heat exhaustion, a heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids.
Remove any tight or unnecessary clothing.
Take a cool shower, bath, or sponge bath.
Apply other cooling measures such as fans or ice towels.
If such measures fail to provide relief within 15 minutes, seek emergency medical help, because untreated heat exhaustion can progress to heat stroke.
After you’ve recovered from heat exhaustion, you’ll probably be more sensitive to high temperatures during the following week. So it’s best to avoid hot weather and heavy

Risk Factors for Heat Exhaustion
Heat exhaustion is strongly related to the heat index, which is a measurement of how hot you feel when the effects of relative humidity and air temperature are combined. A relative humidity of 60% or more hampers sweat evaporation, which hinders your body’s ability to cool itself.
The risk of heat-related illness dramatically increases when the heat index climbs to 90 degrees or more.
So it’s important — especially during heat waves — to pay attention to the reported heat index, and also to remember that the heat index is even higher when you are standing in full sunshine.
If you live in an urban area, you may be especially prone to develop heat exhaustion during a prolonged heat wave, particularly if there are stagnant atmospheric conditions and poor air quality. In what is known as the”heat island effect,” asphalt and concrete store heat during the day and only gradually release it at night, resulting in higher nighttime temperatures.
Other risk factors associated with heat-related illness include:
Infants and children up to age 4, and adults over age 65, are particularly vulnerable because they adjust to heat more slowly than other people.
