Summer Is Here


By Nancy Hart

Our summer Search and Rescue missions can bring us into some long hot days. It's important to know the signs and symptoms of heat illnesses for ourselves, for our subjects, and for our teammates. I know this well now after my experience at this year's County Fair. It was in the upper 90s on Friday and a whopping 105 degrees on Saturday. Even with sunscreen, I was sunburned on Friday. My body's cooling system just couldn't keep up on Saturday with the burn and the even higher temperatures. Although I drank plenty of water and wore sunscreen, I still succumbed to heat exhaustion by late Saturday. And like the subject in Diane Blue's scenario at last month's full team training, I tried to keep going!  Thanks to a teammate who kept insisting I had too much sun, I finally signed out and spent the next two days nursing a headache and staying indoors. Be safe out there!

Heat Illnesses To Be On The Watch For

Heat edema (and it starts)
Heat causes blood vessels to dilate (open up) and as the body is starting to have trouble with using salt to sweat out, fluid will pool in the hands and legs. Ever get those puffy fingers when running or hiking?

Heat exhaustion (milder initial stage)
Move into an air-conditioned environment and don’t go back out into the sun for at least a day or two or the condition will return and possibly be worse!
• profusely sweating
• rapid weak pulse
• rapid breathing (just can’t “catch your breath”)
• blood pressure drops when standing up (you feel dizzy)
• fatigue (you might feel a little “out of it” and “tired”)
• reddened face changes to -> pale, cool, and moist
• headache
• muscle cramping
• nausea (sometimes vomiting)

Heat stroke (next stage, can be deadly!!)
Immediately get out of the sun, in an air-conditioned room preferably, and sponge cool water on the skin. Call for an ambulance to the emergency room.
• sweating has stopped!! – skin is dry, red and hot (body’s sweating mechanism has failed)
• body temperature is up over 101 degrees F
• confusion (Can your teammate or subject remember where they are? What the plans were for the day? What day of the week it is? Their name or your name?)
• throbbing headache and nausea
• severe cramps (as if muscles are encased in cement and you can’t move)
• pulse is fast, breathing rapid, blood pressure low
