Excessive sweating almost never causes physical harm, but the social and emotional toll on a person can be very serious. The recommended treatment depends on your problem: soaked shirts, smell, or yellow armpit stains.
You can reduce all of these to an extent with over the counter treatments and changed habits.
Here are some ways to prevent underarm sweat:
1. Shower or bathe regularly to reduce scent.
Bacteria on your skin can turn old sweat into smelly armpits. Shower daily to wash away the sweat before this happens.
Try ending your shower with a minute or two of cool or cold water. This will lower your surface temperature, making you less likely to sweat right away.
Pat your armpits dry with a soft towel. Vigorous scrubbing can stress your skin and cause more sweating
