Can a short resting heart rate and HRV measurement upon waking using a smartphone app quantify individual stress responses in free-living individuals?
A short resting heart rate and HRV measurement upon waking using a smartphone app can effectively quantify individual stress responses in free-living conditions.
< 0.05, d = 0.47, effect size = moderate) during sickness. Acute stressors analysis revealed how HRV is a more sensitive but not specific marker of stress. In conclusion, a short resting heart rate and HRV measurement upon waking using a smartphone app can effectively be used in free-living to quantify individual stress responses across a large range of individuals and stressors.
