Heart Rate Variability and Prematurity

Before the start of the program and after one week of adherence to the program, two sessions will be conducted with a psychologist in order to define each participant's individual resonance frequency (i.e., breathing rhythm allowing for cardiac coherence), using the Nexus program from Mindmedia company. Then, each participant will receive training on the HRVB program using an Emwave device. The HRVB program itself will be carried individually for 20 min daily over the course of two weeks. Five daily sessions of 10 minutes will be considered as the minimum adherence to the program. Each participant will be asked to report in a diary all eventual major stressful life events.
