Background. Back in 1990, Limansky hypothesized acupuncture points (AP) as polymodal re- ceptors of the ecoceptive sensitivity system. In the process of hypothesis development in 2003 an existence of separate functional system of regulation of electromagnetic balance of organism has been substantiated and a working conception of light therapy has been formulated. Recently, we found that disturbances of the geomagnetic field cause a significant immediate modulating effect on the level of immune parameters in the blood. The data available in the literature give grounds for assumptions about the direct effect of disturbances of the geomagnetic field on immunocytes, and indirectly, through immunotropic neurotransmitters and hormones. Our hypothesis is as follows. Disturbances of the geomagnetic field are perceived by acupuncture points (APs). The information obtained is transmitted to neurons and endocrinocytes, the mediators of which, in turn, affect im- munocytes. The purpose of this study is to test this hypothesis.
