Hyperhidrosis is characterized by what condition?

Hyperhidrosis is characterized by excessive perspiration. This condition occurs when the body's sweat glands become overactive, leading to more sweating than what is necessary for thermoregulation. Individuals with hyperhidrosis may experience sweating in specific areas, such as the palms, feet, underarms, or face, often without any physical activity or heat present to trigger it. This can result in discomfort and social anxiety for those affected. Understanding hyperhidrosis is essential in athletic training, as excessive sweating can impact performance and hydration levels during physical activities.
