Assessment of blue light impact on human internal organs by heart rate variability

Abstract

The paper presents the results of quantitative studies of the heart rate variability detected when the subject was exposed to the preferred light stimulus with a wavelength of 460 nm (blue color). The use of the variational pulsometry method showed the possibility of assessing the state of homeostasis, the interaction of sympathetic and parasympathetic regulation circuits. In the course of the experiment, the activity of various links of the regulatory mechanism was assessed and a general picture of the adaptive response of the organism to the preferred blue light was revealed.
