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...

Heart rate variability (HRV), the change in the time intervals between successive pairs of heartbeats, is influenced by interdependent regulatory systems operating over different time scales to adapt to psychological challenges and environmental demands. Low age-adjusted HRV is predictive of upcomin...

Introduction There is a long history of pre-deployment PTSD prevention efforts in the military and effective pre-deployment strategies to prevent post-deployment PTSD are still needed. Materials and Methods This randomized controlled trial included three arms: heart rate variability biofeedback (HRV...

Objectives Acute coronary syndrome as an acute oxygenated blood deprivation to the heart muscle due to atherosclerotic plaque rupture in the coronary artery followed by thrombosis is possibly associated with changes in the Earth’s local time varying magnetic field as they strongly influence ho...

HeartMath Institute has dedicated over 25 years of scientific research into the study of the physiology of learning, resilience and performance. Most of us have been taught in school that the heart is constantly responding to "orders" sent by the brain in the form of neural signals. However, it is n...

The aims of this study are: to modify dysfunctional negative emotions during competition, by using mental training techniques. Improving behavior of athletes is possible by reducing stress and anxiety. Problem Statement First testing took place during 05-06.02.2015, subjects aged between 12...

Literature has established the effectiveness of self-regulatory techniques using Heart Rate Variability (HRV)-Biofeedback Technology in improving individual’s heart coherence. The current study aims to evaluate the effectiveness of Quick Coherence Technique, a self-regulatory technique, t...

The research was generally motivated by a dearth of studies on joy, and particularly inspired by a book of joy celebrating the inter-spiritual dialogue between the Dalai Lama and Desmond Tutu. Its aim was to investigate whether the direct contemplation of joy would be associated with improvemen...
