Sweat

by Peter Mellow, Lecturer, Sport and Health Science Dept. AUT Akoranga Campus


It's something that even your closest friends may not tell you. Along with bad breath, body odour is one of the least talked about subjects. I mean, can you remember when you were last at a party and the topic was sweating or bad breath!! Enough said! But with everyone working out in close proximity to each other in a gym, the subject does arise from time to time.

According to a medical researcher (Krause) sweat glands are less numerous in the neck and back with about 417 per square inch, and most numerous in the palm of the hand with 2,800 present. The total number is about 2,381,248 on the average person. ( What a job, counting sweat glands! ) Put together they would give a total surface area for evaporation of 8 square inches. (1) They are very important in maintaining a stable temperature by allowing sweat to evaporate away and thus cool the body.

If they didn't work correctly, during exercise the body would soon overheat and lead to a heat injury, heat cramps, heat syncope ( fainting ) , heat exhaustion, heat stroke and even death. Most considerate exercisers attending a gym will wear a deodorant for the comfort of others exercising around them. If you don't you should seriously consider doing so as we don't smell our own odour as well as others can. Even people who think they don't sweat enough to use a deodorant should think twice.

The choice of deodorant is extremely important though. Next time you are shopping at a supermarket look at the ingredients in the things we put on our bodies to stop them smelling. If ALUMINIUM CHLOROHYDRATE is one of those listed, steer clear of that product. Aluminium Chlorohydrate is a common substance used in antiperspirants as it retards and sometimes blocks the body's ability to sweat. (2) This can have dangerous health risks for someone who is about to do an intense workout. If the body doesn't sweat, it overheats, you feel bad and could get very sick!

The good news is that deodorants usually don't have this chemical in them. They just provide a pleasant smell to mask the sweat smell. This chemical is normally only found in antiperspirants. So do your body a favour ( and the rest of us ) and use a deodorant instead of an antiperspirant!
