Stress is an inevitable part of human existence, woven into the very fabric of our daily lives. Yet despite its universality, stress remains one of the most misunderstood aspects of our psychological and physiological experience. To truly overcome stress and build lasting resilience, we must first understand what stress actually is, how it manifests in our bodies and minds, and why our modern world seems particularly designed to trigger our most primitive survival responses.

At its core, stress is our body's natural response to perceived threats or challenges. This response system, often called the "fight-or-flight" mechanism, evolved over millions of years to help our ancestors survive immediate physical dangers. When faced with a predator or natural disaster, this stress response would flood the body with hormones like adrenaline and cortisol, heightening awareness, increasing heart rate, and preparing muscles for rapid action. Once the threat passed, the body would naturally return to its baseline state of calm.

The challenge we face today is that our stress response system hasn't evolved to distinguish between a charging lion and a demanding boss, between a natural disaster and a traffic jam, or between physical danger and social embarrassment. Our brains interpret all of these situations as threats, triggering the same physiological cascade that served our ancestors so well but often leaves us feeling overwhelmed and exhausted in our modern context.
