People don’t seem to take heat exhaustion seriously until it happens to them. Most of us have been there: It’s July, you’re outside working in the yard, and you’re too dirty to go into the house for a glass of cold water. Next thing you know, you are nauseated, dizzy and have an intense headache.
At this point most of us quit what we are doing and go inside to cool down. But those who keep at it are now at risk of heat stroke, which is extremely dangerous and possibly life-threatening.
As our world gets warmer, we hear about more people, especially high-school athletes, dying from heat exposure. People of all ages are at risk of heat related illness, whether working out strenuously or just puttering outside. The risk of heat illness goes up significantly if you have heart, lung or kidney disease or if you are overweight. Certain drugs can also increase your risk of heat illness, especially diuretics, tranquilizers, high blood pressure medicines and antidepressants. All of these inhibit your ability to sweat, which will send your internal temperature soaring. There are two different types of heat illness—heat exhaustion and
heat stroke.
Symptoms of heat exhaustion are: dizziness, weakness, nausea, headache, and cold and clammy skin.
Those with heat exhaustion should move to a cool area and rest with their head in a low position. They should drink plenty of cold water and put cold compresses to the back of their neck and to the forehead.
Symptoms of heat stroke are: headache, numbness, confusion, elevated blood pressure and pulse rate, and profuse sweating.
Heat stroke is a medical emergency and requires rapid treatment to ensure the health of the victim. The sufferer must be immediately cooled in an ice bath to prevent further health implications. Come back next week for my tips on how to avoid heat related illness.
