Sponsor's own description
Photobiomodulation (PBM) is a form of light therapy that uses red or near-infrared light to influence biological processes. In prior studies, PBM has been shown to improve various physiological functions, including tissue repair, inflammation, and cognitive performance. However, little is known about its impact on autonomic nervous system regulation. Thus, the goal of this study is to evaluate the effects of PBM on vagal activity, as measured by heart rate variability (HRV), in healthy adults undergoing experimental stress.
