Document Summary
Chronic stress can kill brain cells, unraveling chromosomes, increasing fat. Baboon models were used to find chronic stress relationships in humans. Humans do not know how to control stress responses hyperventilate, muscles tense (controlling is not an option) Stress is the body"s way of rising to a challenge. Onset of stress is lack of control and predictability. The higher in the hierarchy- the higher the possibility of stress or disease. When stressed the body begins to shut down the immune system leading to ulcers- disrupts our body"s healing ability. Stress can clog arteries, reduce the flow of red blood cells and lead to increased arthrosclerosis. Stress affects the hippocampus (shrunk the part of the brain responsible for memory. Chronic stress can change the structure- lose the ability to remember things. Acute stress- stops us from remembering things short-term. Stress, position on the social hierarchy and weight gain (dangerous fat) can be related to chronic stress pathways.
