Memory, it turns out, is one of the major factors mediating the dialogue between sensation and emotional experience
How your memories impact your immune system, why moving is one of the most stressful life-events, and what your parents have to do with your predisposition to PTSD

I had lived thirty good years before enduring my first food poisoning — odds quite fortunate in the grand scheme of things, but miserably unfortunate in the immediate experience of it. I found myself completely incapacitated to erect the pillars of my daily life — too cognitively foggy to read and write, too physically weak to work out or even meditate. The temporary disability soon elevated the assault on my mind and body to a new height of anguish: an intense experience of stress. Even as I consoled myself with Nabokov’s exceptionally florid account of food poisoning, I couldn’t shake the overwhelming malaise that had engulfed me — somehow, a physical illness had completely colored my psychoemotional reality.
This experience, of course, is far from uncommon. Long before scientists began shedding light on how our minds and bodies actually affect one another, an intuitive understanding of this dialogue between the body and the emotions, or feelings, emerged and permeated our very language: We use “feeling sick” as a grab-bag term for both the sensory symptoms — fever, fatigue, nausea — and the psychological malaise, woven of emotions like sadness and apathy.
Pre-modern medicine, in fact, has recognized this link between disease and emotion for millennia. Ancient Greek, Roman, and Indian Ayurvedic physicians all enlisted the theory of the four humors — blood, yellow bile, black bile, and phlegm — in their healing practices, believing that imbalances in these four visible secretions of the body caused disease and were themselves often caused by the emotions. These beliefs are fossilized in our present language —melancholy comes from the Latin words for “black” (melan) and “bitter bile” (choler), and we think of a melancholic person as gloomy or embittered; a phlegmatic person is languid and impassive, for phlegm makes one lethargic.
And then French philosopher and mathematician René Descartes came along in the seventeenth century, taking it upon himself to eradicate the superstitions that fueled the religious wars of the era by planting the seed of rationalism. But the very tenets that laid the foundation of modern science — the idea that truth comes only from what can be visibly ascertained and proven beyond doubt — severed this link between the physical body and the emotions; those mysterious and fleeting forces, the biological basis of which the tools of modern neuroscience are only just beginning to understand, seemed to exist entirely outside the realm of what could be examined with the tools of rationalism.
For nearly three centuries, the idea that our emotions could impact our physical health remained scientific taboo — setting out to fight one type of dogma, Descartes had inadvertently created another, which we’re only just beginning to shake off…
