Beat the Heat

It's been nearly two years since a five-day heat wave led to more than 700 heat-related deaths in Chicago. And, while this summer's heat isn't forecast to be fatal, it can still be dangerous when temperatures soar. Be prepared to beat the extreme heat with these tips for surviving a hot and humid summer:

• Drink plenty of fluids. Limit alcohol and caffeine, which can dehydrate you.
• Fans are generally helpful, but can be harmful if the temperature is higher than 95 degrees and the humidity is greater than 50 percent. Sweat won't evaporate in these conditions, so a fan would only heat your skin.
• Some medications can increase your risk of heat exhaustion. Ask your physician for detailed information.
• Older adults need to be extra careful in the heat, especially those with an existing medical condition, such as heart disease. If you don't have air conditioning, stay with a family member or friend who does, go to a cooling center, or visit the library or mall.
• Check on children. Your kids may play too hard and not recognize signs of heat exhaustion.
• If you suspect heat exhaustion - characterized by weakness, dizziness, heavy sweating and nausea - move the person to a cool area and give him or her plenty of fluids. If not treated, heat exhaustion can lead to heat stroke, which requires prompt medical attention.
