What is the term for lack of perspiration?

The term for lack of perspiration is anhidrosis. This condition refers to the absence of sweating in response to heat or exercise, which can lead to overheating and other health issues, as sweating is a critical mechanism for regulating body temperature. Anhidrosis can result from various factors, including certain medical conditions, genetics, or damage to the sweat glands.

Hyperhidrosis, on the other hand, refers to excessive sweating, which is the opposite of anhidrosis. Bromidrosis and osmidrosis are related to abnormal body odor associated with perspiration, rather than the absence of perspiration itself. Understanding these terminology distinctions is essential for identifying various sweating disorders and their implications for health and treatment.
