Hyperhidrosis is a condition characterized by excessive sweating that goes beyond what is needed to regulate body temperature. It often affects specific areas such as the hands, feet, underarms, or face and can significantly interfere with daily activities. This excessive sweating is caused by overactive sweat glands and can occur even in cool temperatures or at rest. People with hyperhidrosis may experience discomfort, frequent clothing changes, and difficulty with social interactions due to visible sweat. It can also lead to feelings of embarrassment or self-consciousness, impacting emotional well-being.
