“Findings such as these can change the way we handle chronic stress. When we are mired in stress, what we desperately need to do is minimize the novelty in our lives. We need familiarity. But quite often we seek out the exact opposite, responding to chronic stress at work, for example, by taking a vacation in some exotic place, thinking that the change of scenery will do us good. And under normal circumstances it does. But not when we are highly stressed, because then the novelty we encounter abroad can just add to our physiological load. Instead of traveling, we may be better off remaining on home turf, surrounding ourselves with family and friends, listening to familiar music, watching old films. Exercise, of course, can help, in fact there are few things better at preparing our physiology for stress. But when someone is this far into chronic stress its effects, suggests Stephen Porges, are mostly analgesic, possibly because exercise treats us to a shot of natural opioids. Again, what we really need is familiarity.”
