Detecting stress-anxiety level via WBD101 in-ear Heart Rate Variability (HRV) by the Chinese University of Hong Kong



Stress, anxiety and mental health are increasingly important personal health topics alongside physical health, and since the onset of Covid-19, society is placing less taboo on people who disclose that they have these health issues.


Ninety (90) nursing students put on earphones that can monitor their HRV (milliseconds changes between each heart beat) 10 minutes before, during, and 10 minutes after a stressful mock skill competency assessment. The results indicated clearly that their HRV decreased as the actual assessment period approached, indicating an increased stress-anxiety level, but as the skill competency assessment ended, their HRV increased favourably in as quick as 10 minutes after.
