What effect does prolonged exposure to high cortisol levels have on the body?

1. Increased muscle mass

2. Weight gain

3. Improved sleep patterns

4. Decreased appetite

The correct answer is: Weight gain

Prolonged exposure to high cortisol levels is primarily associated with weight gain due to a combination of factors. Cortisol, which is a stress hormone produced by the adrenal glands, influences metabolism, appetite, and fat storage. When cortisol levels remain elevated over time, it can lead to an increase in appetite and cravings for high-calorie foods, particularly those high in sugar and fat. Additionally, cortisol promotes the storage of fat, especially in the abdominal area, which contributes to overall weight gain. While high cortisol levels can also lead to muscle breakdown and other health issues, the most notable effect is an increase in body weight as a result of increased fat storage and altered metabolism. Other options, like improved sleep patterns and decreased appetite, contradict the well-documented effects of chronic stress and elevated cortisol levels. Typically, high cortisol is associated with sleep disturbances and a likely increase in appetite rather than a decrease.
