“…In fact, the effects of negative exchanges often outweigh the effects of positive exchanges (see reviews by Brooks & Dunkel Schetter, 2011; Rook, 1998). For example, negative interaction, but not positive interaction, has been found in large prospective studies to predict allostatic load (dysregulation across multiple physiological systems that underlies many chronic diseases; Seeman, Gruenewald, Cohen, Williams, & Matthews, 2014), hypertension (Sneed & Cohen, 2014), incident coronary events (De Vogli, Chandola, & Marmot, 2007), and mortality due to stroke (Tanne, Goldbourt, & Medalie, 2004). Whether different kinds of negative interactions have specific health effects is not well understood, but they may evoke distinctive negative emotions (such as anger versus sadness) that, in turn, have distinctive health effects (Kiecolt-Glaser, McGuire, Robles, & Glaser, 2002).…”
