The amount an individual body perspires varies from person to person, so you shouldn't worry too much about the amount you sweat, there's little you can do about it, unless it's really excessive, in which your GP can discuss that issue with you. Sweat is odourless - the smell it generates is caused by bactieria which breed in sweat which is left on the skin for too long. This is easily rectified - ensure you wash frequently, and your clothes are fresh - try to ensure cotton is next to your skin, and use an anti-perspirant. These simple remedies will alleviate your odour problem
