A drop in HRV isn't generally good. So I check the paper, and found this:
> No significant changes were found in heart rate variability or resting heart rate over the course of the study in either of the groups (Figures 4C and 4D)
There was a reduction respiratory rate for those an increase in daily positive affect. Bottom line, unclear if this particular study points to a positive health outcome other than feeling happier.
- curiouska 4y agoFrom the paper: Interestingly, change in respiratory rate was negatively correlated with change in daily positive affect (Figure S5; r = - 0.24, p < 0.05), suggesting that participants who showed the highest reduction in respiratory rate also showed the highest daily increase in positive affect over the course of the study (Figure S5).
