Woman who avoided sunlight since childhood breaks bones while turning in bed in China

A 48-year-old woman from Chengdu, China, suffered bone fracture simply by turning over in sleep, an injury the attending doctor linked to years of excessive sun avoidance. According to the doctor, the woman had avoided sunlight since childhood, never wore short sleeves outdoors, and was meticulous about sun protection. This eventually led to a critical deficiency in vitamin D.
