Precautions in the heat

Humid or muggy conditions, which add to the discomfort of high temperatures, occur when a "dome" of high atmospheric pressure traps hazy, damp air near the ground.

Warm temperatures combined with high humidity can pose a risk of heat-related illness and death.

In Wisconsin, generally when temperatures approach or rise above 90 degrees Fahrenheit, the Department of Health and Family Services recommends taking the following precautions: * Avoid strenuous activity during the hottest part of the day. If such activity is unavoidable, drink plenty of fluids and take frequent breaks in air-conditioned or shaded areas. Consider monitoring body weight and oral temperature.

* A weight loss of more than 2 pounds or an oral temperature above 99 degrees Fahrenheit is cause for concern. Do not leave anyone - children, disabled individuals, pets - in cars for even brief periods. Temperatures can rise to life-threatening levels in a matter of minutes.

* Make frequent checks on the status of elderly or ill relatives or neighbors. If necessary, move them to an air-conditioned environment during the hottest part of the day.

* To avoid dehydration, a conscious effort should be made to drink more fluids during hot weather. Rapid weight loss may be a sign of dehydration.

* Don't drink liquids that contain caffeine, alcohol, or large amounts of sugar - these actually cause you to lose more body fluid.

* Use fans to increase ventilation. If the temperatures exceed 90 degrees Fahrenheit, instead of having a fan blow hot air in from a window, have the fan blow the hot air to the outside.

* At extreme high temperatures, a fan loses its ability to effectively reduce heat-related illness. Cool showers, baths and sponge baths can be used to reduce body temperatures. In

addition, wet clothing has a cooling effect.
