GD9 CTW fileÒ  Medical 10, Ñ The weather is as unpredictable as the stock market. Sometimes the weather can change so quickly that we are caught unaware and find ourselves having to make changes in our daily routines or planned activities. If temperatures soar, we must make adjustments to our lifestyle so that we do not suffer from too much heat. Several terms are associated with heat. A heat wave is a prolonged period of excessive heat and humidity. A heat index is a combination of relative humidity and high temperatures. When the two are combined, what we feel in temperature may be several degrees higher than the actual temperature. If a heat wave is imminent, there are several actions you can take to minimize danger to your health. Strenuous activity should be avoided; if you must work outside, you should do it during the coolest part of the day, either early morning or near dusk. If possible, stay indoors as much as possible. Drink plenty of water, even if you do not feel thirsty. Avoid drinks with caffeine or alcohol in them. Wear lightweight clothing and be sure your clothing is light colored. Light colors will reflect some of the sun's heat and help your body maintain lower temperatures. If you are exposed to high temperatures over a long period of time, you may suffer from heat exhaustion. If this happens, quickly get out of the heat and move to a cooler place. Apply cool, wet cloths to your body and drink cool water. Finally, eat more often, but do not take in too much food.
