Interested in heart-rate variability as a biomarker of stress resilience? Researchers from the University of Southern Denmark randomly assigned 90 adults to 10 days of 20-30 minutes if either app-based mindfulness training, listening to music, or a control group that did nothing. All participants had their heart rhythms continuously monitored. After 10 days, the mindfulness group reported greater increases in mindfulness, less perceived stress, and fewer breaths per minute than the other groups. The mindfulness group showed increases in heart-rate variability, suggesting an enhanced ability to cope with life’s ups and downs.
