**Abstract**

The study of the effects of the space weather on the human body was carried out at the Spitsbergen archipelago. A geophysical feature of the arch. Spitsbergen is its location in the cusp region—a kind of funnel on the dayside of the magnetosphere, where phenomena of space weather most express. Diverse radiation (from ULF to VHF) and waves in the field of polar cusp, covering the entire range of the body rhythms, give credit for studying the effects of space weather in the field of polar cusp. Assessment of the relationship between the dynamics of the monthly morbidity in Russian settlements and indicators of space weather revealed that, practically, all forms of morbidity are associated with solar activity and with the local geomagnetic activity in the polar cusp. A difference in correlations between the monthly incidence of residents in the Barentsburg and geocosmic agents during the polar day and the polar night was found. The links between the incidences of the population and the peculiarities of space weather will make it possible to develop prognoses of the morbidity for preventive measures aimed at increasing human health in high latitudes.
