A little bird told me the other day that it might not be a bad time to talk about the impact of emotions on our health—particularly our choice to express or not express them. I’ve heard people around me share that they’re worn out lately—that emotions have imposed a toll regardless of how well they keep their own in check. It got me thinking. Increasingly, researchers uncover the remarkable imbrication of mental and physical well-being. How we nourish or neglect our physical selves affects how we feel psychologically. Likewise, the emotional terrain we traverse throughout a day, in turn, elicits its own physiological feedback. Yet in this culture, there’s a certain esteem for the stiff upper lip. We restrain ourselves for the sake of others—our perception of their comfort and/or of their opinion of us. But are we sacrificing something in doing so? When does the polite instinct to suppress our emotions benefit us, and when does it backfire? (This Mark's Daily Apple article was written by Mark Sisson, and is narrated by Tina Leaman)
