Trait Mindfulness Is Associated With the Self-Similarity of Heart Rate Variability

Area of Science:

• Psychophysiology
• Neuroscience
• Mindfulness Research

Background:

• Trait mindfulness is associated with enhanced self-regulation and adaptation.
• Heart rate variability (HRV) serves as a physiological marker for self-regulation and adaptation capacity.

Purpose of the Study:

• To investigate the relationship between trait mindfulness and HRV, focusing on the crosstalking interactions between HRV parameter pairs.
• To explore how trait mindfulness relates to HRV at absolute, difference-change, and crosstalking levels.

Main Methods:

• Seventy-four undergraduate students' trait mindfulness was assessed using the Mindful Attention Awareness Scale (MAAS).
• Nine HRV parameters were recorded across four experimental phases: calming, mental arithmetic, recovery, and mindfulness practice.
• Analysis examined HRV at absolute, difference-change, and crosstalking levels.

Main Results:

• Trait mindfulness showed a significant positive correlation with the self-similarity of crosstalking HRV parameter pairs.
• No significant correlations were found between trait mindfulness and HRV parameters at the absolute or difference-change levels.
• Findings suggest trait mindfulness enhances the ability to maintain autonomic nervous system (ANS) function homeostasis.

Conclusions:

• Trait mindfulness is specifically linked to the dynamic interplay of HRV parameters, reflecting sophisticated self-regulatory processes.
• The capacity for maintaining autonomic nervous system homeostasis improves with higher levels of trait mindfulness.
• Future research could explore interventions to enhance trait mindfulness and its impact on HRV dynamics.
