Armpits, also known as axillae, are the areas under our arms where they connect to our shoulders. They play a crucial role in our body by allowing our arms to move freely. The skin in this area is sensitive and contains many sweat glands, which help regulate our body temperature by producing sweat when we get hot. In addition to their functional role, armpits are often associated with personal hygiene. Many people use deodorants or antiperspirants to manage body odor and sweat. It's important to keep this area clean to prevent irritation and maintain overall skin health.
