The human stress response evolved as a critical survival mechanism that protected ancestors in life-threatening situations. However, this biological system was never designed to remain continuously activated, as modern life often demands. Understanding what occurs inside the body during stress can illuminate why chronic activation of this response creates problems.

These changes were adaptive for acute threats but become counterproductive when the stress response stays switched on. The biological mechanisms that once saved lives can damage health when they operate persistently.
