What stress does to your body

When we experience excessive stress—whether from internal worry or external circumstance—a bodily reaction is triggered, called the "fight or flight" response. Originally discovered by the great Harvard physiologist Walter Cannon, this response is hard-wired into our brains and represents a genetic wisdom designed to protect us from bodily harm. This response actually corresponds to an area of our brain called the hypothalamus, which—when stimulated—initiates a sequence of nerve cell firing and chemical release that prepares our body for running or fighting.

When our fight or flight system is activated, we tend to perceive everything in our environment as a possible threat to our survival. By its very nature, the fight or flight system bypasses our rational mind—where our more well thought out beliefs exist—and moves us into "attack" mode. This state of alert causes us to perceive almost everything in our world as a possible threat to our survival. As such, we tend to see everyone and everything as a possible enemy. Like airport security during a terrorist threat, we are on the look out for every possible danger. We may overreact to the slightest comment. Our fear is exaggerated. Our thinking is distorted. We see everything through the filter of possible danger. We narrow our focus to those things that can harm us. Fear becomes the lens through which we see the world.

We can begin to see how it is almost impossible to cultivate positive attitudes and beliefs when we are stuck in survival mode. Our heart is not open. Our rational mind is disengaged. Our consciousness is focused on fear, not love. Making clear choices and recognizing the consequences of those choices is unfeasible. We are focused on short-term survival, not the long-term consequences of our beliefs and choices. When we are overwhelmed with excessive stress, our life becomes a series of short-term emergencies. We lose the ability to relax and enjoy the moment. We live from crisis to crisis, with no relief in sight. Burnout is inevitable. This burnout is what usually provides the motivation to change our lives for the better. We are propelled to step back and look at the big picture of our lives—forcing us to examine our beliefs, our values and our goals.
