Born with well-developed sweat glands, people who sweat easily are more likely to have foot odor. Because the sweat glands in the palms and soles of the feet are more distributed than other parts of the body, and because of wearing shoes and socks, it is easy to produce foot odor.

In addition, age is also a factor. Adolescent children are energetic and active, so they sweat more; In middle-aged and elderly people, sweat glands atrophy and the amount of sweating decreases, so the foot odor originally caused by sweating may gradually disappear.

2. Disease factors:

The most common diseases are athlete's foot, onychomycosis, and keratolysis (pits similar to acne scars appear on the thick skin of the sole after the stratum corneum is infected by bacteria). Most patients sweat a lot, and the accumulation of sweat leads to the growth of bacteria and mold. In other words, sweating causes diseases such as athlete's foot, which in turn causes foot odor.

3. External factors:

This is related to work and personal hygiene habits. Some jobs must always wear airtight shoes and socks, such as police, soldiers or workers. If you sweat regularly, the chance of foot odor will increase greatly. Bad personal hygiene habits, such as always wearing the same pair of shoes and socks or taking a shower in a hurry, not paying attention to the cleanliness of the joints between toes and feet, and not drying feet, are the chief culprits of foot odor.
