What causes sweating on the soles of the feet when the weather is not hot?

Excessive sweating of the feet despite cool weather may be due to physiological factors such as inappropriate footwear or socks, or pathological causes such as hypoglycemia or bacterial infection of the feet.

I. Physiological Causes

Wearing thick shoes or socks can trap heat and prevent proper ventilation of the feet, leading to sweaty feet even in cool weather. This condition does not affect other parts of the body and can be resolved by promptly changing into more breathable footwear and socks.

II. Pathological Causes

1. Hypoglycemia

Patients with hypoglycemia often experience excessive foot sweating. When the body is in an excited state, its ability to regulate blood glucose decreases, resulting in increased secretion of adrenaline. This can cause symptoms such as pallor, tremors, and profuse sweating, including on the soles of the feet. Affected individuals should rest in bed and consume sugar promptly to alleviate symptoms quickly.

2. Bacterial Infection of the Feet

Bacterial infections in the feet may also lead to excessive sweating even when the weather is cool. This condition typically requires treatment with antibiotics under a doctor's guidance, such as cefuroxime axetil tablets or amoxicillin capsules.

In addition, hyperhidrosis may also be caused by hyperthyroidism. If symptoms significantly affect daily life, prompt medical attention is recommended. As part of daily care, it is important to wash the feet every day, keep them clean and dry, and prevent bacterial growth.
