We all love basking in sunlight streaming through a window, but is it giving us our daily dose of Vitamin D? Sadly, the answer is generally no. Standard glass used in windows blocks UVB rays, the very type of sunlight our skin needs to produce Vitamin D.
Think of it this way: you're getting the light and warmth, but not the beneficial UVB rays that kickstart Vitamin D synthesis. While some specialty windows might allow UVB penetration, most don't.
So, what's the takeaway? Don't rely on sunlight through a window for your Vitamin D. Instead, spend some time outdoors (without sunscreen for a limited time when the UV index allows), consider Vitamin D-rich foods, or talk to your doctor about supplementation. Getting your Vitamin D levels checked is also a good idea to understand your personal needs. Enjoy the view from your window, but step outside to truly soak up the sun's goodness!
