Recently, a shocking medical case has raised public concern about the health risks of extreme sun avoidance. A 48-year-old woman suffered a spinal fracture (脊柱骨折) while simply turning over in bed. Test results revealed her vitamin D levels were less than one-third of the normal range, directly linked to her decades-long sun protection habits. Since childhood, she had completely covered her skin outdoors, almost wearing long sleeves year-round and always applying sunscreen when going outside.

Vitamin D plays a critical role in bone health and calcium (钙) absorption. “All the bones in our body are renewed every 10 years, but from the age of 30, we start to lose bone mass at a rate of 0.5 to 1% per year. Low calcium intake, lack of sunlight exposure and vitamin D all hinder calcium absorption,” Jiang Xiaobing, director of the Department of Orthopedic Spine Surgery at the Second Affiliated Hospital of Guangzhou Medical University said. While sunscreen effectively prevents skin damage from UV rays, complete sunlight blockage deprives (使丧失) the body of its primary natural source of vitamin D. Medical experts emphasize balanced sun exposure.

The case went viral on social media, sparking debates about beauty standards. Many users connected the patient’s behavior to the preference for fair skin. Dr. Jiang Xiaobing commented: “It is not uncommon to see people covering their entire body from head to toe to protect themselves from the sun. It is really unhealthy.”

This incident highlights the complex relationship between health and beauty practices. While skin cancer prevention remains crucial, doctors warn that overprotection causes new problems — weakened immunity, increased depression risks, and bone disorders. As modern lifestyles shift indoors and sun protection products become more advanced, healthcare professionals urge the public to reconsider extreme behaviors and adopt science-based approaches to sun safety.
