Patient's question:
My baby was born during a cloudy weather, so now that he's three months old, he hasn't been out in the sun at all. I live on the 7th floor where the sunlight is very good, but my son is calcium deficient. I'm wondering if sunlight through the glass is effective. If it is, how long should I expose him to the sun?Doctor's answer:
Sunning through a glass window has no effect on calcium supplementation. This is because glass absorbs the ultraviolet rays that are effective. Therefore, experts recommend that people should go out and sunbathe in fresh air and sunny places.
