How does stress typically impact blood glucose levels?

Stress can significantly influence blood glucose levels primarily due to the physiological response the body has to stress. When a person experiences stress, the body releases stress hormones such as cortisol and adrenaline (also known as epinephrine). These hormones prepare the body for a "fight or flight" response, which includes mobilizing energy reserves.

As a result, these hormones promote the release of glucose from the liver into the bloodstream, increasing blood sugar levels. This is a protective mechanism that ensures that the body has a quick source of energy available to deal with the stressful situation. Therefore, during episodes of stress, blood glucose levels can rise, making it crucial for individuals, especially those with diabetes, to monitor their blood sugar closely during stressful times.

In contrast, the other options do not accurately represent the typical physiological response to stress in relation to blood glucose levels.
