    “

    Chronic stress is a full-on biological hijack where a system meant for ten minutes of terror runs for ten months, causing your survival mechanisms to essentially become your health’s biggest enemies.

    자주 묻는 질문

    The biology of chronic stress involves a full-on biological hijack where the body's internal wiring stays in a high-alert state for extended periods. Originally designed as a masterpiece of evolution to protect humans from predators, this system now reacts to modern triggers like work emails or bills. When the fight-or-flight response stays active for months rather than minutes, it disrupts almost every single process in the human nervous system and negatively impacts long-term physical health.

    In modern life, the fight-or-flight response often struggles to distinguish between physical threats and everyday stressors. While the system evolved to help us survive encounters with predators, the brain now treats passive-aggressive messages or financial concerns like a literal bear. This causes hormones to stay 'on' constantly, leading to a state of chronic stress where the body remains ready to sprint or fight despite there being no immediate physical danger.

    The evolutionary biology of stress is problematic today because our systems were meant to handle short bursts of terror, not the 'micro-bears' of a 24/7 digital world. We have transitioned from ten minutes of survival-based fear to ten months of constant pressure, such as checking Slack late at night. This prolonged activation of hormones and the nervous system creates a chaotic internal environment that the human body was never supposed to maintain indefinitely.
