Relationship between variations in population health disorders in a subarctic region and heliogeophysical factors and oxygen status of surface air under different levels of solar activity
BACKGROUND: It is generally recognized that human health depends on the changes of space weather. However, the cyclic interactions of specific groups of diseases with the main components of solar radiation and its derivatives remain unresolved.

Circannual variations in partial oxygen density depending on solar activity level and climatic zone
BACKGROUND: Some medical weather classifications identify reduced partial oxygen density in the air as a key parameter affecting human well-being. This parameter can be modulated not only by meteorological factors but also by the helio-geophysical environment. It should be noted that synoptic combinations with elevated oxygen content are not considered among the weather types, although several studies have shown that hyperoxia can have adverse ef…
The contribution of weather factors to seasonal variations in oxygen partial density in different climatic zones
Background: Currently, there is growing concern about changes in the oxygen content in the surface air layer. There are weather classifications where the determining meteotropic effect affecting human health is the value of oxygen partial density, but among these types of weather, hyperoxia situations are not considered, although in a number of studies attention has been drawn to the negative impact on human health of high oxygen content in inhal…
Influence of solar radiation components on partial oxygen density in the surface air layer in subarctic and subtropical regions
