The study was conducted in nine voluntary workers in order to evaluate the efficiency of the pro-gram. A baseline evaluation was conducted on psychological variables (anxiety, perceived-stress, w...

The purpose of this study is to determine the effect of 8 weeks of HRV (Heart Rate Variability) training on the happiness and coherence levels of university students. …

Providing effective strategies for managing stress in the moment helps mitigate the physical, emotional, and psychological impacts associated with caring for others and promotes resiliency. Staff may...

This study used ambient heart rate monitoring among health care workers to determine whether a novel measure of heart rate variability (HRV), as well as sleep disturbances, fatigue, or cognitive performance differed among non-rotating night shift nurses relative to those working permanent day shifts...

Whenever an internal desynchronization in frequency occurs, the possibility of beats arises, as found and modeled earlier (1, 2). Adynamia observed about twice a year in a 62-year-old woman (JF) may relate to beats between desynchronized circadian systems, in view of differences in period found...
