What is the term for the inability to sweat?

Anhidrosis is the correct term for the inability to sweat. This condition can lead to overheating of the body because sweating is a vital physiological response that helps regulate body temperature. When an individual cannot produce sweat, it can result from a variety of factors, including genetics, certain medications, or skin diseases.

The condition must be addressed, as sweating plays an essential role in thermoregulation during physical activity or in hot environments. Unlike other conditions or terms listed, anhidrosis specifically focuses on the absence of the sweating mechanism, which distinguishes it from related but different phenomena.
