As Selye pointed out, the salient stressors in the lives of most human beings today — at least in the industrialized world — are emotional. Just like laboratory animals unable to escape, people find themselves trapped in lifestyles and emotional patterns inimical to their health. The higher the level of economic development, it seems, the more anaesthetized we have become to our emotional realities. We no longer sense what is happening in our bodies and cannot therefore act in self-preserving ways. The physiology of stress eats away at our bodies not because it has outlived its usefulness but because we may no longer have the competence to recognize its signals. (p36)

Kelly McGonigal, a health psychologist at Stanford University, warned about the dangers of stress for a full decade before she realized that maybe it was her advice, rather than stress itself, that was sending people to their graves faster. “I’m converting a stimulus [stress] that could be strengthening people into a source of disease.” With a breakthrough in her thinking, and some powerful new research, McGonigal made a complete turnaround. Turns out, stress might just be our friend. Just as you put stress on a muscle to make it stronger (by lifting weights or running), emotional stress can make us physically and psychologically stronger too. McGonigal now highlights new research showing that when you change your mind about stress, you can literally change your body’s physical reaction to it. In an eight-year study, adults who experienced a “lot of stress” and who believed stress was harmful to their health had a 43% increase in their risk of dying. (That sure stressed me out.) However, people who experienced an equal amount of stress but did not view stress as harmful were no more likely to die! McGonigal says that physical signs of stress (a pounding heart, faster breathing, breaking out in a sweat) aren’t necessarily physical evidence of anxiety or signs that we aren’t coping well with pressure. Instead, we can interpret them as indications that our body is energized and preparing us to meet the next challenge. The bottom line is, science has now proven that how you think about stress matters — the story you attach to stress. Telling yourself it’s good for you instead of harmful could mean the difference between a stress-induced heart attack at 50 or living well into your 90s.

Scientists have learned that animals that experience prolonged stress have less activity in the parts of their brain that handle higher-order tasks — for example, the prefrontal cortex — and more activity in the primitive parts of their brain that are focused on survival, such as the amygdala.

“My body reacts very strongly to stress

Stress is like fire: When controlled and used for a purpose, it serves us well. Left unbridled, it can consume us. In amounts that our body is capable of adapting to, certain stresses are beneficial. Exercise, for example, is a stress.

The bottom line is, science has now proven that how you think about stress matters — the story you attach to stress. Telling yourself it’s good for you instead of harmful could mean the difference between a stress-induced heart attack at 50 or living well into your 90s.

Cellular Senescence: As cells undergo stress, they occasionally become "senescent," both losing their ability to divide and, simultaneously, becoming resistant to death. These "zombie cells" can't be removed from the body. They build up over time, infect neighboring cells, and ultimately create a zombie apocalypse of inflammatory debilitation.

Stress can be a killer and is far too prevalent in today’s workplaces. You may not die because of stress but stress can easily kill your energy levels, motivation, relationships, health and mindset.

In moments of great stress, every life form that exists gives out a tiny subliminal signal.

But the larger point is that we can now see that depriving systems of stressors, vital stressors, is not necessarily a good thing, and can be downright harmful.

Once, unfortunately, in a crisis situation (as the Greek poet Archilochus pointed out so long ago) we don't rise to the level of our expectations, we fall to the level of our training. Once again, the issue is fear. The more fear in the equation, the fewer options at our disposal. In times of strife, the brain limits our choices to speed up our reaction times. The extreme example being, fight or flight, where the situation is so dire, that the brain gives us only potential actions. Freezing is the third, yet the same thing happens to a lesser degree under any high stress conditions. And the responses we fall back upon under duress, are the ones we fully automatized: those habitual patterns we've executed over and over again.

prolonged and extended exposure to stress overwhelms your system, which then has to compensate and overwork (i.e., “toxic stress”), which shortens your lifespan.2

I look at it this way: the instinctive response to danger — the stress response — consists of fight, flight, or freeze. These three strategies help us survive physically, but when they’re applied to our mental and emotional functioning, we get into trouble. When there’s no enemy to defend against, we turn on ourselves. “Fight” becomes self-criticism, “flight” becomes self-isolation, and “freeze” becomes self-absorption, getting locked into our own thoughts.

too much sugar, too much stress, too much sitting, too much pollution, too many pills, too many pesticides, too many screens, too little sleep, and too little micronutrients. These trends — with trillions of dollars behind them — are causing epidemic levels of mitochondrial dysfunction and underpowered, sick, inflamed bodies.
