Anhidrosis is the condition characterized by a lack of sweating, which is crucial for regulating body temperature. Sweat plays a vital role in cooling the body through evaporation, and individuals with anhidrosis may experience discomfort in hot weather or during physical exertion due to their inability to cool down effectively. This condition can be caused by various factors, including certain skin disorders, nerve damage, or as a result of medications.

In contrast, hyperhidrosis refers to excessive sweating, which is the opposite of anhidrosis. Apocrine glands are one of the types of sweat glands that become active during puberty and release substances that can cause body odor when interacting with bacteria on the skin; they play a specific role rather than indicating a lack of sweating. Hyperthermia refers to an elevation in body temperature, often due to environmental factors or overexertion, and is not a direct indication of sweat production or lack thereof. Therefore, anhidrosis stands out as the correct answer in this context.
