A recent study in the journal Proceedings of the Royal Society B showed that individuals born in a solar maximum period (more ultraviolet radiation) had a 5.2 year shorter lifespan, on average, than those born in a solar minimum timeframe (less ultraviolet radiation). Furthermore, women with lower socioeconomic status who were born in a solar maximum timeframe also had decreased fertility as well as reduced lifetime reproductive success. The findings were based on church records spanning the years 1750-1900 involving 9062 people in Norway. Since families with low socioeconomic status mostly worked in fields and therefore had more sun exposure and were most affected by ultraviolet radiation, the authors concluded that women should not sunbathe while pregnant in order to improve outcomes.
A renowned specialist in female fertility, Dr. Shahryar Kavoussi, states,”Ultraviolet radiation (UVR) has been shown to affect different aspects of human health and this study suggests that UVR is associated with reproductive efficiency and human lifespan as well”.
