In recent years, Heart Rate Variability (HRV) has garnered significant attention as a promising biomarker for assessing emotional regulation, particularly in therapeutic settings. HRV refers to the variation in time intervals between consecutive heartbeats, and it provides a window into the functioning of the autonomic nervous system. Higher HRV is often associated with greater adaptability and resilience, indicating a healthy balance between sympathetic and parasympathetic activity—essential for effective emotional regulation. Understanding the relationship between HRV and emotional regulation has profound implications for psychotherapy and mental health interventions, as it offers a tangible physiological measure to assess the emotional wellbeing of individuals.

Several studies have highlighted the value of HRV in understanding emotional regulation. For example, Petrocchi and Cheli (2019) discuss the connection between HRV and the "social brain," emphasizing its implications for psychotherapy. They suggest that higher HRV is linked with improved emotional and social functioning, which in turn makes it a valuable biomarker for assessing emotional regulation capabilities in patients undergoing therapy (Petrocchi & Cheli, 2019). This connection between HRV and social interaction plays a critical role in determining how individuals engage emotionally, which is particularly relevant for therapeutic interventions that target interpersonal functioning.
Similarly, research by Cai et al. has explicitly explored the relationship between resting HRV and emotion regulation. Their findings indicate that individuals with higher resting HRV tend to use more adaptive emotional regulation strategies, suggesting that HRV can serve as an indicator of a person's ability to manage their emotions effectively. This supports the idea of HRV as a practical tool for assessing and even predicting emotional responses in clinical practice (Cai et al.).
Kemp (2016) takes this a step further by examining HRV in relation to affective disorders such as depression and anxiety. Kemp's research demonstrates that individuals with reduced HRV often experience impaired emotion regulation, which is a hallmark of these affective disorders. The use of HRV as a biomarker can therefore be instrumental in identifying emotional dysregulation in patients and guiding targeted therapeutic interventions (Kemp, 2016).
Together, these studies underscore the role of HRV as an important biomarker for assessing emotional regulation in therapeutic settings. By providing measurable insights into autonomic function, HRV helps therapists better understand their patients' emotional states and tailor interventions accordingly. This growing body of research suggests that incorporating HRV measurements into clinical practice could greatly enhance the effectiveness of therapeutic approaches aimed at improving emotional health and resilience.
