We’re also realizing that epigenetic changes from our parents and the emotional climate in which they lived, can plant negative seeds in us. In our own lives, medical researchers in the last several decades have figured out that chronically feeling negative emotions can weaken our immune system, while long-term positive ones boost it.

These emotions include depression, chronic stress, and loneliness. Steve Cole, Ph.D., from the Cousins Center for Psychoneuroimmunology at UCLA found out how it works. He proved a few years ago that negative emotions affect the expression of genes associated with the immune system. They suppress them. While positive emotions boost expression.

But how far back does the effect go? A new study published in the Proceedings of the National Academy of Sciences has a surprising answer. Here, researchers found that adults who endured a contentious childhood had suppressed immune systems even decades later, making them more susceptible to the common cold and other illnesses.

Psychologists from a number of universities contributed to the study. They wanted to know how a parent’s separation and how they handled it affected a child’s health long-term. Those parents who had a contentious separation, who wouldn’t speak to one another or…
