One compelling argument as to why feet can smell worse than armpits is that the feet contain more sweat glands than the armpits, which can lead to more bacteria growth and a stronger odor. While both the feet and armpits contain apocrine glands, which produce sweat that can mix with bacteria and create an odor, the feet contain more eccrine glands, which produce a higher volume of sweat. This excess sweat can create a moist environment in shoes and socks, which can further promote bacterial growth and contribute to foot odor.
In addition, the feet are often covered in socks and shoes, which can trap moisture and sweat, making it difficult for the feet to breathe and further contributing to the growth of odor-causing bacteria. This can be exacerbated by certain footwear choices, such as closed-toe shoes or boots, which can trap heat and sweat and create an ideal environment for bacterial growth.
Another factor that can contribute to foot odor is the presence of fungi, such as athlete’s foot. Fungal infections can cause a foul smell, as well as itching and peeling of the skin.
While both feet and armpits can develop unpleasant odors, the higher number of sweat glands in the feet, combined with the warm and moist environment created by socks and shoes, can make them more prone to developing a stronger and more persistent odor than the armpits.
In conclusion, while the exact causes of foot and armpit odor may vary from person to person, the higher number of sweat glands and the warm, moist environment of the feet make them more likely to develop a stronger and more persistent odor than the armpits.
