“…In contrast, social support has been suggested to maintain or even improve health by reducing psychobiological reactivity to stressors (Lepore, 1998;Christenfeld and Gerin, 2000). Indeed, various findings suggest that social support attenuates a variety of psychological and physiological stress responses (Seeman and McEwen, 1996;Uchino et al, 1996;Christenfeld and Gerin, 2000;Heinrichs et al, 2003;Uchino, 2006;Wirtz et al, 2006;Nausheen et al, 2007;Wirtz et al, 2009), whereas loneliness or social inhibition are associated with heightened psychobiological stress responses (Habra et al, 2003;Nausheen et al, 2007). Furthermore, poor anger regulation as indicated by higher aggression, hostility, or outwardly negatively expressed anger (anger-out) has been associated with heightened physiological reactivity to 4 mental stress, particularly of the cardiovascular system (Chida and Hamer, 2008).…”
