Is sweating necessary?

whenever i work out, usually to different programs on dvd, i do so inside my living room where the central ac is on. my husband always works out in the garage because he says its more effective when your body sweats. I sweat some, but of course not as much as if i was in a hot garage. is it really necessary or does it matter?
Is sweating necessary?
Sweating is the way we humans cool off and regulate our body temperature. To that degree, it is necessary. We can control some of the odor in specific places, but it would never be a good idea to try to stop all sweating. We also breathe through the skin. If you were able to completely close the pores, we would suffocate.





So, sweating is necessary, though some people do it with far less wetness than others. If you are exercising hard and STOP sweating, you are in big trouble.
