Medical and Heliometeorological Service

**Medical-heliometric service** This is a complex service that combines medical heliothermal data and data on heliogeophysical conditions when used in medical practice. It is based on the principle of joint assessment of the impact of space and terrestrial phenomena, as well as a temporary version of the analysis of a dynamic multifactor system. The basis of the medical-heliometric service is long-term observations of the cyclicity of solar activity, astrophysical phenomena, climatic and geophysical conditions, where any individual factor is the cause of many
