Most of us are self-conscious of body odor and sweat even when we work out or play sports, but is antiperspirant a good idea when you know you’re going to be working up a sweat? Sweating is healthy. Sweating allows toxins to be released from your body (consider the sweat lodge or a sauna) and that is a good thing. Sweating also helps regulate your body’s temperature. Your body’s temperature range is very small. Just a few degrees up or down and you can put yourself at great risk.
When you wear antiperspirant the chemicals aluminum-zirconium, aluminum chlorohydrate or aluminum chloride plug up sweat pores minimizing the amount of sweat that occurs. Excess sweat can cause embarrassing marks on your clothes and get unpleasant odors started. Deodorants on the other hand contain chemicals that specifically mask odor. Many deodorants contain an antiperspirant component giving you sweat reduction and odor masking.
Antiperspirants can come in useful when you are at a formal function, work in an office, or just out on a date. You don’t want to have to worry about smelly sweat and wet armpits. But when you are working out or playing sports it is better to let your sweat glands naturally run their course, and allow your sweat to cool your body during exercise.
