Esthetics Core Written Practice Test

Anhidrosis refers to:

1. Deficiency of perspiration

2. Excessive oil production

3. An increase in body temperature

4. A skin age spot

The correct answer is: Deficiency of perspiration

Anhidrosis refers to a deficiency or absence of perspiration. This condition can affect the body's ability to regulate temperature, as sweating is a key mechanism for cooling the body. When an individual experiences anhidrosis, they may be at risk for overheating, particularly in warm environments or during physical activity. The correct understanding of anhidrosis highlights its impact on the body's thermal regulation and overall health. The other options do not align with the definition of anhidrosis. Excessive oil production relates to conditions like seborrhea, while an increase in body temperature typically refers to hyperthermia rather than a lack of sweating. Skin age spots, also known as liver spots or solar lentigines, are unrelated to perspiration and involve pigmentation changes in the skin. Therefore, recognizing that anhidrosis specifically pertains to reduced sweating is essential in understanding its implications for health and wellness.
