Self-esteem fluctuations and cardiac vagal control in everyday life
چکیده انگلیسی

It has been proposed that self-esteem buffers threat-responding. The same effect is ascribed to the vagus nerve, which is a primary nerve of the parasympathetic nervous system. Consequently, it has been suggested that self-esteem and cardiac vagal tone are interconnected on a trait, as well as on a state, level. In this study, we examined the relationship of vagal cardiac control and self-esteem fluctuations across a single day using ecological momentary assessment. Eighty-four participants were recruited, and self-esteem, negative affect, and vagal tone were recorded throughout a 22-hour period. Men provided higher self-esteem ratings than women, but the negative relationship between self-esteem and negative affect was stronger in women. Moreover, controlling for potential confounds (e.g., age, BMI, depressive symptoms, smoking status, regular physical activity), we observed that for men, self-esteem was significantly positively associated with cardiac vagal tone, whereas for women it was not. These findings suggest that the relationship between self-esteem and vagal innervation of the heart during daily life is sex-specific and might involve different central-autonomic pathways for men and women, respectively.


► Self-esteem and cardiac vagal tone buffer threat responding.
► We assessed self-esteem, negative affect, and cardiac vagal tone throughout a day.
► Self-esteem is related to higher cardiac vagal tone in men but not in women.
► Negative affect is more strongly associated with self-esteem in women than in men.
► Different central-autonomic pathways might be involved in men and women.
