Light, reflective clothing should be worn, especially if you are in direct sunlight. A spray bottle filled with water can be used to mist your skin frequently to increase evaporative heat loss. If you are inside without air-conditioning, a fan will improve evaporative heat loss. Some medications can interfere with the body's normal temperature control mechanisms, especially those with anticholinergic properties. Check with your pharmacist or physician concerning any untoward effects of your medications relating to body temperature regulation.
Small children deserve special consideration during periods of excessive heat.
Give your infant plenty to drink, and dress the infant appropriately for the temperature. The best way to monitor fluid balance in an infant is to take note of the frequency of wet diapers. If your infant is not wetting diapers as often as usual, you need to give the infant more liquid. If you do not have air-conditioning, an infant should sleep in the coolest room in your home. A room on the lowest floor and on the side of the house away from the sun will usually be the coolest.
