| Abstract: | Recent research on the communication of affection has begun to illuminate its implications for mental and physical health. Specifically, when compared to non-affectionate people, self-report studies have indicated that highly affectionate people are less susceptible to depression and stress, and endocrine studies have shown that highly affectionate people have more differentiated 24-hour cortisol rhythms (a pattern indicative of adaptive physiological stress management). The present studies extend this knowledge by focusing on the associations that trait affection has with cardiologic (resting heart rate), vascular (resting blood pressure), and metabolic (glycosylated hemoglobin) properties of physical health. Participants in both studies provided self-assessments of their trait levels of expressed affection and received affection (the latter for use as a covariate). Resting heart rate and blood pressure were assessed in the first study, and glycosylated hemoglobin was assessed in the second study. Results indicate that when the influence of received affection is controlled for, trait expressed affection was inversely related to resting blood pressure and glycosylated hemoglobin (but not heart rate), suggesting that the expression of affection is associated with a healthy vascular and metabolic profile. |
