Doctor Oz did a segment on body odor. Just because you sweat does not mean you have to stink… sweat and body odor are two different things. Why do you get body odor and what can you do to beat it? Dr Oz said that odor is usually associated with sweating, but this does not have to be the case. There are three areas of the body that are associated with both sweat and body odor: the pubic area, feet and underarms. Dr Oz said that in these three areas you have a higher concentration of sweat glands.
