Understanding Foot Odor: What Causes Smelly Feet?
Foot odor, also known as bromodosis, is a common condition that can be embarrassing and uncomfortable. It's caused by a combination of sweat and bacteria. Our feet contain more sweat glands than any other part of the body – approximately 250,000 sweat glands per foot! While sweat itself is odorless, the bacteria that thrive in the warm, moist environment of our shoes and socks break down the sweat, producing volatile fatty acids responsible for the unpleasant smell.
Several factors can contribute to foot odor, including:
- Hyperhidrosis: Excessive sweating, also known as hyperhidrosis, provides a breeding ground for bacteria. Although some believe it's linked to thyroid conditions, the Mayo Clinic says it can occur even in people who are otherwise healthy. Hyperhidrosis Info
- Poor Hygiene: Not washing your feet regularly or failing to dry them thoroughly after washing can exacerbate foot odor.
- Type of Socks and Shoes: Synthetic socks and shoes that don't allow your feet to breathe can trap moisture, increasing bacterial growth.
- Fungal Infections: Athlete's foot, a fungal infection, can also contribute to foot odor.
- Diet and Stress: Certain foods and stress can sometimes trigger increased sweating, potentially worsening foot odor.

Changing socks throughout the day, especially if you have sweaty feet, can drastically reduce foot odor. Choose socks made from breathable materials like cotton or wool, which help wick away moisture.
