Excessive sweating in the palms and toes is often due to Hyperhidrosis, where the sweat glands are overactive. You can help control it by keeping the hands and feet dry, using strong antiperspirant lotions or powders, wearing breathable footwear, and managing stress or anxiety, which can trigger sweating. In more persistent cases, doctors may recommend treatments such as prescription creams, medications, or procedures like Iontophoresis. If the sweating is severe or affecting daily life, it is best to consult a doctor for proper evaluation and treatment.
