Negative Thoughts Proved to Change Your Genes
#Emotional states and Gene Changes
Our body interprets all negative emotions as epigenetic stress signals. Researches confirm the correlations between emotional disturbances—such as schizophrenia, depression, panic, and post-traumatic stress disorder (PTSD) and gene expression in the brain with compelling evidence. Patterns of gene expression in the brains of unhappy individuals are different from those of happier individuals. This partly explains why unhappy depressed people have weakened immune systems more susceptible to illness.
#Brain’s Reaction to Unhappiness
Researches found that depression and elevated cortisol correlate with changes in the expression of many of the genes in the limbic system of the brain, which is central to our stress response.
 limbic system: a complex system of nerves and networks in the brain, in charge of our instinct and mood. It controls our basic emotions, ranging from fear, pleasure to anger. Further, the limbic system drives hunger, sex, dominance.
#Chronic Depression and Immune Cell Aging
Emotions turning genes on and off. Studies have verified the fact that chronic depression accelerates immune cell aging, which makes people more susceptible to illness indeed. In other words, mental trauma accelerates early aging. Studies found that people living with major depressive disorder are biologically older than people without depression. Again, depression leads to premature aging.
 People with certain genes are more prone to unhappy emotions.
