In the bustling world of the twenty-first century, stress has become an unwelcome companion for millions of people worldwide. From the moment we wake up to the sound of our alarm clocks to the final thoughts that race through our minds before sleep, we are constantly navigating a landscape filled with deadlines, responsibilities, and endless demands on our time and energy. This pervasive presence of stress in our daily lives has transformed what was once an adaptive survival mechanism into a chronic condition that threatens our physical health, mental wellbeing, and overall quality of life.

The human stress response, often referred to as the "fight or flight" mechanism, evolved over millions of years to help our ancestors survive immediate physical threats. When faced with a hungry predator or natural disaster, this physiological response would flood the body with stress hormones like cortisol and adrenaline, heightening alertness, increasing heart rate, and redirecting blood flow to essential muscles needed for quick action. Once the threat passed, the body would naturally return to its baseline state of calm, allowing for rest and recovery.

However, the nature of stress in contemporary society has fundamentally changed. Unlike our ancestors who faced occasional acute threats, we now live in a world of chronic, low-level stressors that rarely allow our nervous systems to fully relax and reset. The constant ping of notifications on our smartphones, the pressure to maintain perfect social media profiles, financial worries, work deadlines, relationship challenges, and the overwhelming amount of information we process daily all contribute to a state of perpetual activation that our bodies were never designed to handle.
