A change in the frequency spectrum of a person's pulse under the influence of light of different wavelengths has been established. It has been shown that in the light stimulation phase, different colors cause functional changes in the internal organs in the subjects. At the same time, the effects of the photostimulus on the internal organs are not equivalent and depend on the initial functional state and the typology of the subject. Depending on the type of exposure, the same photostimulus can cause contrasting changes in the frequency parameters of pulse signals recorded on the radial arteries of human wrists.
Using the Automated pulse diagnostic system (APDS), the possibility of a quantitative assessment of correcting the functional state of a human organism by the method of spectral analysis of pulse waves (while the subject is exposed to light of different wavelengths) has been revealed. It has been shown that photostimuli have unequal effects on the internal organs, which depends on the functional state of the subject. At the same time, the extreme phtostimuli (blue and red) provide either toning, or relaxing effect on the psychophysiological state of the subject. The contrast effect of light on the human body is one of the promising technologies for managing the functional psychophysiological state.
The paper presents the results of experimental studies of optical radiation impact of three colors (yellow, green and blue) on the functional state of human internal organs using the method of energy coefficient. It has been shown by quantitative assessment that a biological response of the body is not determined by the properties that are common to all the waves of the visible range, but it depends on the wavelength of optical radiation. Short-term exposure to optical radiation of the visible range does not lead to any significant and stable changes in the functioning of internal organs. The results of the research can be used to develop technologies for managing the mental and physiological state of a person.
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.
The article presents the results of experimental studies of heart rate variability obtained by the exposure of the subject to the preferred color stimulus — optical radiation with a wavelength of 530 nm (green). The use of the method of variational pulsometry has demonstrated the possibility of assessing the state of autonomic homeostasis, the interaction of sympathetic and parasympathetic regulation circuits. In the course of the experiment, the degree of activity of various links of the regulatory mechanism has been assessed and the general picture of the adaptive response of the body to light has been revealed.
