People who frequently suppress their emotions suffer fewer depressive symptoms if they have higher resting heart rate variability.

Key findings
Expressive suppression was generally linked to higher depressive symptoms and more perceived stress, while cognitive reappraisal was tied to better well-being. However, having higher resting heart rate variability buffered the negative effects of expressive suppression on depressive symptoms. For individuals with low heart rate variability, suppressing emotions predicted higher depressive symptoms, whereas those with high heart rate variability showed no such negative association.
Methodology
Researchers tracked 267 older adults, including 167 recently bereaved spouses and 100 matched controls, over a 6-month period across 3 visits. At the first visit, they measured participants' resting heart rate variability for 5 continuous minutes and assessed their self-reported emotion regulation strategies. They then tracked participants' depressive symptoms and perceived stress levels across all three visits.
Limitations
The study is purely correlational, meaning it cannot prove that high heart rate variability directly causes resilience against emotional suppression. It relied on self-reported questionnaires to measure the frequency of emotion regulation strategies rather than directly assessing how effectively participants applied them. Additionally, the sample consisted of older adults who were mostly non-Hispanic White, so the findings may not generalize to younger or more racially diverse populations. Lastly, heart rate variability was measured only once at baseline rather than tracking how it shifted over the course of the study.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
The use of cognitive reappraisal is associated with greater psychological well-being, higher positive affect, and lower negative affect.
Evidence for the claim as stated.
While retrospective trait questionnaires link cognitive reappraisal to reduced global negative affect and improved well-being, a daily diary study tracking real-time emotional adjustments in high-stress roles found that managing daily negative emotions had no significant short-term daily impact on stress or well-being.
Evidence for the claim as stated.
Expressive suppression is generally associated with reduced positive affect, higher daily stress, and increased depressive symptoms, although its negative effects are not uniform across all individuals.
Evidence for the claim as stated.
High resting heart rate variability serves as a physiological buffer, preventing the increase in depressive symptoms typically experienced by people who frequently suppress their emotions.
Evidence for the claim as stated.
There is a discrepancy regarding whether managing negative emotions impacts daily outcomes; longitudinal research on older adults links general emotional suppression to higher depressive symptoms and stress, whereas daily diary research in nurses indicates that managing negative emotions has no significant daily effect on stress or well-being.
Evidence for the claim as stated.
An individual's baseline resting heart rate variability acts as a protective buffer, meaning that those with higher resting HRV do not suffer the elevated depressive symptoms typically associated with the frequent use of emotional suppression.
Evidence for the claim as stated.
