Which condition is characterized by a lack of sweat production?

1. Anhidrosis

2. Hyperhidrosis

3. Atopic dermatitis

4. Psoriasis

The correct answer is: Anhidrosis

Anhidrosis is the condition characterized by a lack of sweat production, which can be particularly significant because sweating is an essential bodily function that helps to regulate temperature and maintain homeostasis. Individuals with anhidrosis may experience overheating and are at risk for heat-related illnesses, especially in hot environments or during vigorous activities. Hyperhidrosis, on the other hand, is the excessive production of sweat, opposite to anhidrosis. Atopic dermatitis and psoriasis are both inflammatory skin conditions that can lead to other symptoms, but they do not primarily involve sweat production. In summary, anhidrosis directly describes the absence of sweat, making it the correct answer to the question.
