Which variable can negatively impact collagen production?

Chronic stress can negatively impact collagen production due to its effects on the body’s physiological processes. When a person experiences chronic stress, the body increases the production of stress hormones, such as cortisol. Elevated levels of cortisol can lead to heightened inflammation and may inhibit the activity of fibroblasts, which are the cells responsible for producing collagen. Additionally, stress can affect nutrient absorption and overall health, further compromising the body’s ability to synthesize collagen effectively.

In contrast, adequate hydration supports the skin's elasticity and collagen structure; regular exercise enhances blood circulation, promoting nutrient delivery to tissues; and a balanced diet provides essential nutrients, such as vitamins C and E, that are crucial for collagen synthesis. These factors contribute to maintaining healthy collagen levels, whereas chronic stress stands out as a detrimental influence.
