Excessive Heat Warning in Effect for Entire Region

An Excessive Heat Warning and an Air Quality Alert are in effect through this evening. Today will be the hottest day of the year with high temperatures expected to climb between 94 and 100 degrees this afternoon. The heat index, or the measure of what it actually feels like, may reach or exceed 105 degrees. Use extreme caution if you have to be outside.

Heat is the number one weather-related killer in the United States, resulting in hundreds of fatalities each year. In fact, on average, excessive heat claims more lives each year than floods, lightning, tornadoes and hurricanes combined. Heat disorders generally have to do with a reduction or collapse of the body's ability to shed heat by circulatory changes and sweating or a chemical imbalance caused by too much sweating.

When the body heats too quickly to cool itself safely, or when someone loses too much fluid or salt through dehydration or sweating, his or her body temperature rises and heat-related illness may develop. Studies indicate that the severity of heat disorders tends to increase with age. Conditions that cause heat cramps in a 17-year-old may result in heat exhaustion in someone 40 and heat stroke in a person over 60.

More than 1,250 people died in a disastrous heat wave in 1980. In the heat wave of 1995, more than 700 deaths in the Chicago area were attributed to heat. Between 1999 and 2003, heat-related deaths increased by 54 percent across the United States. During this time, 3,442 deaths resulting in exposure to extreme heat were reported for an average of about 688 deaths a year.

There are several risk factors to take into account. People who have access to three hours of air conditioning a day are less likely to die. Poor health, obesity, diabetes, and cardiovascular disease are all factors for heat-related deaths. Older people need to be careful since changes in physiology affect how a person responds to heat as he or she ages, and older people don't sweat as much as younger people.

Take it easy today and tomorrow. Children, seniors, and anyone with health problems should stay in the coolest available place. Certainly dress for Summer by wearing lightweight, light-colored clothing to reflect heat and sunlight. Drink plenty of water or other non-alcohol or decaffeinated fluids. Your body needs water to keep cool.

Some relief is expected by the latter half of the weekend when daytime temperatures reach the mid 80s, and Monday will feature a high temperature close to 80 degrees, which is more in line with this time of the year. However, look for the mercury to climb back to the upper 80s by the middle of next week. It's still July!
