Underarm sweat is a common problem that can be embarrassing and uncomfortable. It can also lead to body odor, which can be even more embarrassing. There are a number of things you can do to avoid underarm sweat, including using antiperspirant or deodorant, wearing loose-fitting clothing, and avoiding caffeine and alcohol.
Antiperspirant and deodorant are the most effective way to avoid underarm sweat. Antiperspirant works by blocking the sweat glands, while deodorant simply masks the smell of sweat. It is important to apply antiperspirant or deodorant to clean, dry skin. You should also apply it at night, so that it has time to work before you start sweating the next day.
