How We Become Addicted to Stress…

“Stress is not a state of mind… it’s measurable and dangerous, and humans can’t seem to find their off-switch.” These words of warning come from renowned author and award-winning neurobiologist Robert Sapolsky in the documentary Stress: Portrait of a Killer.1
The film, jointly produced by National Geographic and Stanford University where Dr. Sapolsky is a professor and scholar, shows just how dangerous prolonged stress can be.
As we evolved, the stress response saved our lives by enabling us to run from predators or take down prey. But today, we are turning on the same “life-saving” reaction to cope with $4 per gallon gasoline, fear of public speaking, difficult bosses, and traffic jams—and have a hard time turning it off.
Constantly being in a stress response may have you marinating in corrosive hormones around the clock.
This film shows the impact stress has on your body, how it can shrink your brain, add fat to your belly, and even unravel your chromosomes. Understanding how stress works can help you figure out ways to combat it and reduce its negative impacts on your health.
Monkey See, Monkey Do
Dr. Sapolsky has learned a great deal about the human stress response and its effects on your body by studying primates in Africa. Every year, he spends a few weeks in the Kenyan wilderness studying baboon societies that have intraspecies social and psychological tumult that mimics the stress of modern man.
He monitors their adrenal hormone levels, namely adrenalin (epinephrine) and glucocorticoids (such as cortisol). The fact that baboons live in communities with hierarchical structures led Dr. Sapolsky to one of his most profound discoveries: baboon stress is related to hierarchy, or social rank.
The higher a baboon’s rank, the less stress it experiences. The lower its rank, the higher its stress. More importantly, Dr. Sapolsky discovered that the low ranking “have-nots” of the baboon world experienced higher heart rates and blood pressure than the “haves.”
Arteries in the “have-not” monkeys filled up with plaque, restricting their blood flow and increasing their heart attack risk. This was the first time stress was scientifically linked to deteriorating health in wild primates. As it READ MORE: http://articles.mercola.com/sites/articles/archive/2014/07/05/stress-effects
