Giving adequate fluids—it is best to give fluids that contain both salt and sugar. If the person isn't able to drink, it may be necessary to give fluids by IV.
Encouraging the person to rest
Moving the person to a cool, shady area.
Actively cooling the person—the most effective way is called evaporative cooling. In evaporative cooling, the person is sponged with cool water or sprayed with cool mist, and fans are used to blow air onto the person.
Giving IV fluids.
Giving medications—These may be necessary if the person is having seizures or uncontrollable shivering.
Careful monitoring—People who have undergone heat stroke need regular and careful monitoring of body temperature, heart rate, blood pressure, and breathing rate. Blood tests will be repeated at regular intervals to monitor how the body's organs are responding to the shock of heat stroke.
To help reduce your chances of heat exhaustion and heat stroke:
Avoid prolonged exposure to high temperatures.
If you have to work or exercise under hot conditions, drink lots of fluids (preferably sports drinks, which contain both salt and sugar), and take frequent breaks in the shade.
If you have a risk factor for heat exhaustion or heat stroke, be careful participating in activities in hot weather. Take regular rests and drink lots of fluids.
During heat waves, try to spend time indoors with air conditioning or go to an air conditioned shelter. This is especially important for older adults.
