Question
My baby was born during cold weather, so even at three months old, he hasn’t gone outside to get sunlight. We live on the 7th floor, and the sunlight is great, but my son is deficient in calcium. I’m wondering if sunbathing through glass is effective. If it is, how long should we expose him to the sunlight?
Answer
Sunbathing through glass actually has little to no effect on calcium supplementation. This is because glass absorbs the UV rays that are necessary for the process. Therefore, sunbathing through glass is not very effective. Experts recommend that people should go outside and get sunlight in fresh, sunny places instead.
