Excessive sweating of the hands and feet, also called hyperhidrosis, can be frustrating, but it is manageable with the right approach. It usually happens because the sweat glands are overactive and can be triggered by heat, stress, or even without a clear reason. A good first step is to use a strong antiperspirant (not just a deodorant) on the palms and soles at night, when sweating is less, so it works better. Keeping your hands and feet clean and dry, changing socks regularly, and wearing breathable footwear can also help reduce moisture. If sweating is still troublesome, treatments like iontophoresis (a simple procedure that reduces sweating using mild electrical currents) or doctor-prescribed medicines may be useful. In some cases, stress management techniques like relaxation or yoga can also make a difference. Since this condition can vary from person to person, it is best to consult a doctor if basic measures do not help, so that treatment can be tailored to your needs.
