By Marc Sorenson, EdD, for sun exposure and children’s health…
It is well-known that sun exposure is associated with a reduced risk of many major cancers in adults. But what about children? A California study has shown that sun exposure during pregnancies also influences the childhood cancer risk of children who are a result of those pregnancies. In this research, sun exposure, based on the geographical area where the women lived while pregnant, was measured. Then their children were compared in terms of childhood cancer risk, based on high or low sun exposure. Those children whose mothers experienced more sun exposure were less likely to develop acute lymphoblastic leukemia, hepatoblastoma, and non-hodgkin’s lymphoma. The authors of the study make this summary statement: “Our findings suggest that UVR during pregnancy may decrease the odds of some childhood cancers. Future studies should explore additional factors that may be correlated with UVR exposure and possibly include biomarkers of immune function and vitamin D.”
We have discussed in previous blogs the association of sunlight deficiency during women’s pregnancies and the subsequent risk of profoundly increased autism in their children. Therefore, similar results with cancer are not surprising. Safe, non-burning sun exposure has positive effects on at least 100 of the most frightening diseases, many of which will be discussed in my upcoming book that is coauthored by Dr. William B. Grant, and entitled Embrace the Sun. Children, even babies, need at least some sun exposure. And children, if they do not get outdoors in the sun are also subject to a remarkable increase in the risk of myopia.
Take care of your children. Be sure that they play in the sunlight each day, without sunscreen. If any reddening occurs, put them in the shade or cover them up. But don’t deny them their share of sunshine; if you do, their risk of childhood cancers may increase.
