<P> The number of active sweat glands varies greatly among different people , though comparisons between different areas ( ex . axillae vs. groin ) show the same directional changes ( certain areas always have more active sweat glands while others always have fewer ) . According to Henry Gray 's estimates , the palm has around 370 sweat glands per cm ; the back of the hand has 200 per cm ; the forehead has 175 per cm ; the breast , abdomen , and forearm have 155 per cm ; and the back and legs have 60 -- 80 per cm . </P>
