hypohidrosis

This term is a specialized medical descriptor used primarily in clinical settings, dermatology, and pathology. It carries a neutral, diagnostic tone and is rarely used in casual conversation, where a speaker would more likely describe the condition as "an inability to sweat."

As a medical condition referring to a physiological state or deficiency, the term is treated as an uncountable noun. It describes a systemic or localized pathology rather than a discrete object that can be counted.
