The term "underarms" refers to the area located beneath the arms, where the skin is soft and sensitive. This part of the body is also known as the armpit. Underarms play a role in regulating body temperature and are home to sweat glands that help cool the body when it gets hot. Many people use deodorants or antiperspirants to manage odor and sweat in their underarms. These products can help individuals feel fresh and confident throughout the day. Regular grooming, such as shaving or trimming hair in the underarm area, is also common for personal hygiene and comfort.
