What causes sweaty feet?

Excessive sweating of the feet may be caused by physiological factors, or by pathological conditions such as athlete's foot (tinea pedis) and hyperhidrosis. The specific analysis is as follows:

I. Physiological Factors

The human feet contain a large number of sweat glands. Wearing non-breathable shoes can create a moist and warm environment on the soles, preventing sweat from evaporating into the air, which easily leads to excessive foot sweating. This is considered a normal physiological phenomenon.

II. Pathological Factors

1. Athlete's Foot (Tinea Pedis)

Athlete's foot is a fungal infection. Once infected, fungi irritate the skin of the feet, increasing secretions and causing sweaty feet. It may also be accompanied by localized itching. Treatment may include antifungal medications such as bifonazole gel or lamisil cream, used according to medical advice.

2. Hyperhidrosis

Hyperhidrosis is a condition characterized by abnormal, excessive sweating throughout the body due to endocrine disorders or hormonal imbalances. Excessive sweating commonly occurs in areas such as the soles of the feet, armpits, and groin. In daily life, affected individuals may use aluminum chloride solution or aluminum acetate solution to clean areas prone to sweating, as directed by a physician.

In addition to the above relatively common causes, other conditions such as hyperthyroidism may also contribute. It is recommended that patients wear breathable footwear and socks, wash their feet regularly, change socks frequently, and avoid prolonged strenuous exercise to prevent increased sweating and associated discomfort.
