What causes sweaty feet when wearing flip-flops in autumn?

Wearing slippers in autumn may lead to sweaty feet, generally caused by factors such as palmar-plantar hyperhidrosis, overactive sweat glands, or spleen deficiency. Detailed analysis is as follows:

1. Palmar-Plantar Hyperhidrosis

Palmar-plantar hyperhidrosis causes excessive sweating on the hands or soles of the feet, which may also be accompanied by odor. Patients can take medications such as vitamin B1 and oryzanol under medical guidance. Additionally, maintaining foot hygiene and washing feet regularly is important.

2. Overactive Sweat Glands

Excessive sweat gland activity may result in heavy sweating in areas such as the armpits, back, or perineum. When sweat cannot be properly excreted through the glands, it may negatively affect health. A minimally invasive surgical procedure at a hospital can remove the affected sweat glands, effectively treating persistent foot sweating.

3. Spleen Deficiency

Individuals with spleen deficiency tend to have excess dampness in the body and are more prone to sweating, especially in the hands and feet. Dampness in the body tends to sink downward, making the limbs—particularly the feet—more susceptible to sweating. The spleen and stomach are closely related to digestion; poor absorption of food in the gastrointestinal tract can lead to insufficient spleen qi, which in turn may cause inadequate heart qi and increased sweating. For indigestion caused by chronic Helicobacter pylori infection, anti-infective medications can help relieve symptoms. For spleen and stomach weakness due to chronic hepatitis, treating the underlying condition with appropriate medication can improve symptoms.

In addition, sweaty feet when wearing slippers in autumn might also be caused by kidney deficiency. Individuals should maintain proper foot cleanliness, wear loose-fitting shoes and socks with good breathability, and pay attention to foot hygiene.
