The aim of our work was to study possible changes in the cardio-respiratory system under blue light irradiation with wavelength 470 ± 10 nm. Material and methods. A sample of 5 people (3 men and 2 women, average age 55.7 ± 3.0 years) was taken to study three-month dynamics of heart rate and its variability, blood pressure and its variability, cardiac function, respiratory function. Parameters after loading tests before and after travelling to other climatic and geographical conditions and parameters under various level of physical activity were analyzed as well. Subjects from the experimental group had daily phototherapy sessions with blue light generated by bracelet BASI – an autonomous light-emitting device (two sessions of 15 minutes each). In the control group, there were 3 men and 3 women of the same age and body type who spent their experimental time in the Central Russia. Measurements were made with a tonometer and with a device called “spiroarteriocardiaorhythmograph” in three test variants: without a spirometrical mask, with the mask and voluntary breathing (imitation of light hypoxia) and with controlled breathing having frequency 6 cycles per minute. Level of parameter changes was analyzed every experimental month. The discriminant analysis algorithm (direct step-by-step analysis) was applied. Results. It has been found out that preventive phototherapy with blue light courses changes in the cardio-respiratory function which reach the level of statistical significance in case of controlled breathing test.
