Please take it easy in this dangerous heat, drink lots of
water, rest in cool areas, be alert for signs of heat stress, heat exhaustion, and even heat stroke. See http://www.bt.cdc.gov/disasters/extremeheat/heat_guide-page-3.asp for more details. The Chicago area is in its 3rd day of 100+ degree heat. From the CDC: Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. Those most prone to heat exhaustion are elderly people, people with high blood pressure, and people working or exercising in a hot environment. Warning signs of heat exhaustion include the following: The skin may be cool and moist, pulse rate will be fast and weak, and breathing will be fast and shallow. If heat exhaustion is untreated, it may progress to heat stroke. Seek medical attention immediately if any of the following occurs: Symptoms are severe or the victim has heart problems or high blood pressure Otherwise, help the victim to cool off, and seek medical attention if symptoms worsen or last longer than 1 hour.

Heat Stress
The middle of the country is under a weather high-pressure dome which means we are in for intense heat without relief soon. In Chicago, another aspect of weather came in to play today, when fog gathered over the lake and beaches in the Chicago area because the cold lake cooled off the hot air and water droplets condensed in it. The fog caused poor visibility for the lifeguards at the beaches, so 23 of the 24 beaches were closed. Fortunately, it also cooled off the affected areas a little. If you can, stay indoors in cooled air and make sure you drink enough water and clear fluid to replace perspiration and usual metabolism. (Avoid caffeine, alcohol, and sugary drinks as they won’t help.) If you have to go outside, wear light-colored, loose-fitting clothing made of natural fabric such as cotton or linen to reflect the sun. Performance wicking fabrics may also be an option if they work for you. Again, drink lots of clear fluid as previously recommended. Sunscreen, big sunglasses, and wide-brimmed hats to shade your head, face, ears and neck are also appropriate fashion in this sweltering weather. Work-rest regimens need to be considered in this weather to prevent heat stress and heat stroke. Avoid strenuous activities in the hottest part of the day and take frequent breaks. If you feel dizzy, nauseous, fatigue, excessive sweating, headache, stop what you are doing and cool down immediately as fast as you can. Heat Rash--Body powder can help absorb perspiration and prevent heat rash and chafing. |
