What condition is characterized by abnormally excessive sweating not linked to heat or exercise?

Hyperhidrosis is the condition defined by excessive sweating that occurs without any direct connection to heat or physical exertion. This condition can affect specific areas of the body, such as the palms, armpits, and feet, or can be generalized across larger regions. The excessive sweating can occur at any time and can lead to discomfort and social anxiety for those who experience it.

Unlike bromhidrosis, which refers specifically to body odor resulting from sweating, and anhidrosis, which is characterized by an inability to sweat, hyperhidrosis specifically emphasizes the aspect of overproduction of sweat itself. Dermatitis, on the other hand, refers to skin inflammation and does not primarily concern sweating but rather the condition of the skin itself. Therefore, hyperhidrosis is the correct answer as it encompasses the key features of excessive sweating that is not a response to environmental triggers or physical activity.
