Heat Exhaustion

Sometimes heat exhaustion slips up on us incidiously in hot weather. We need to know the symptoms to take defensive action when needed!

Each year when the summer temperature ascends higher and higher, the possibility of too much sun can cause a deadly stroke. When the weather is warm and sultry and in fact hot with high humidity it is sometimes deceiving to our good sense"┬Žit is beautiful outside, things are green and pleasing and we are ready to go for our routine walk or run and enjoy the fresh air and sunshine. We exercise with enthusiasm as usual, not thinking about the extreme heat of this particular day. Heat is generated in the body, and when it is produced faster than the body can cool itself down, then related conditions may occur such as, heat exhaustion, or heat stroke. Our body is a wonderful mechanism, it will try valiantly to cool itself by restricting the blood flow to the kidneys and other internal organs and open the blood vessels near the skin where heat can be dispersed through evaporation. Our body cools itself by primarily through the skin and perspiring.
