Sweaty armpits can be a problem for many people, causing discomfort, social anxiety, and even embarrassment. There are a number of things that can be done to avoid sweaty armpits, including using antiperspirants and deodorants, wearing loose-fitting clothing, and avoiding certain foods and drinks.
Antiperspirants and deodorants work by blocking sweat glands or masking the smell of sweat. Antiperspirants contain aluminum salts that plug sweat glands, while deodorants contain antibacterial agents that kill the bacteria that cause sweat to smell.
