The effect of music embedded with binaural beats on heart rate parameters during nap

Objective To test hypothesis that music embedded with binaural beats can boost activity of parasympathetic part of autonomic nervous system (PPANS) with the development of nap. Material and methods The power of high-frequency component of heart rate variability spectrum computed on successive 2-minute intervals during 20-minute nap was a comparison criterion. The criterion was compared during nap accompanied by music with embedded binaural beats (stimulus condition) and nap in silence (control condition). Results and conclusion Statistical comparison revealed the increase of PPANS activity during nap in stimulus condition vs. control condition. It is consistent with conclusions of other papers about positive effect of sound stimuli embedded with binaural beats on PPANS.
