Abstract <p>Data on the reaction of the human body to the heat impact of woven electric heaters are obtained. To estimate the reaction results, the data are processed considering the calculation of the difference between the temperatures obtained in the heater area with variable and constant heat transfer coefficients to the human body. The obtained results are compared with those of the peripheral microcirculation study using plethysmography and laser Doppler flowmetry. The comparison shows both the coinciding and the original nature of the results; therefore, the proposed approach can be used independently and be combined with other methods, which will allow us to obtain more information about the effect of heat on the microcirculation processes of blood. This article is useful for experts developing heating devices for humans and medicine, as well as for physiologists and medical workers.</p>
