A study claims that exposure to intense sunlight during pregnancy could shorten a child’s lifespan.
According to researchers from the Norwegian University of Science and Technology, people born during years of solar maximum had lived 5.2 years shorter than those born during years with minimal sun activity. In a solar cycle, solar maximum refers to a three-year period of high activity in the sun, while solar minimum refers to an eight-year span of low activity. The study states that the increased levels of the sun’s ultraviolet radiation (UVR) during the solar maximum period can shorten one’s lifespan.
The researchers analyzed the birth records of 9,062 Norwegians born between 1676 and 1878. The age of women during labor and the survival rate of their children were examined. Then, the gathered data were compared with the solar cycle records.
Upon analysis, researchers claim that the increased UVR during solar maximum caused cell damage among the developing infants. Excessive UVR can damage a mother’s folic acid or vitamin B9, which is necessary for a healthy pregnancy.
The authors also noted that women with lower incomes had more sunlight exposures than well-off mothers. Aside from that, researchers added that the mothers’ quality of food intake played a key role in the development of the infants.
While excessive sun exposure may be harmful, humans still need sunlight for the body’s vitamin D production. According to a researcher who studied on the effects of UVR, pregnant women have to find the right balance in getting the needed sun exposure. The benefits of vitamin D include having strong immune system and healthy bones.
