Document Summary
Lecture 2: bio mechanisms of health and disease. Bio mechanisms: otherwise it will happen again. Epigenetics getting a medical intervention also requires changing the behaviour that caused the stress: can change the way your genes express, some genes express momentarily, some genes express over longer periods of time. Lonely people"s gene expression is causing pro-inflammatory cytokines and down-regulates anti-inflammatory cytokines: changing their bodies. Don"t have to spend time while you are trying to do everything else confront your fears. Summary: so much of the stress we experience is due to anticipation. When you are stressed, the calories/fat from food go to your centro-adipose tissue: most harmful weight, central-adipose tissue excretes its" own stress hormones. Going to make you feel more stressed. Components of the central nervous system (test: autonomic nervous system automatically. A lot of stress response originates from autonomic nervous system. That"s why it"s so hard to change/control: sympathetic fight or flight, parasympathetic rest or digest.
