Sweat is part of the body's functions and if you have a lot of problems and you do not sweat you may consider a visit to the doctor’s clinic because it is not normal not to sweat at all. That is also the case if you sweat excessively and you feel like the odour emanated is pretty foul, something that you know is normal. People sweat and it is ok to do it, but as it is something that you do not want to be visible you need to get informed regarding the type of clothing to wear to avoid being all stained with sweat.
