Vitamin D and Sun: A Quick Tip
Vitamin D is one of the most misunderstood vitamins, yet one of the most important. Vitamin D helps your body absorb Calcium, regulates minerals in your bloodstream, and has been shown to improve immune system function. Lack of Vitamin D has been linked to Rickets (soft bones).
Some doctors want you to take a supplement to get enough Vitamin D. Others recommend eating Catfish or Sardines, which naturally have some Vitamin D. But the reality is that Vitamin D is only readily available in enough quantity through the Sun.
However, even then, your body can’t always get enough UVB rays from the sun to convert into Vitamin D. Most people have heard “if you just get 30 minutes a day of sun” you’ll get enough Vitamin D – but that isn’t necessarily true.
Instead, remember this more useful rule of thumb:
If you go outside in the sun, and your shadow is shorter than you are, that is an opportunity to get Vitamin D
The science behind it: This happens when the sun is at more than a 45 degree angle in the sky, when UVB rays are able to reach you through the atmosphere.
It is important to note that not all cities receive enough of this situation throughout the whole year. For example, the southern U.S. receives this sun for more of the year than the northeast. In these cases, you should take a supplement during those months.
Final note: Wearing sunscreen or blocking the sun with clothing will prevent you from absorbing the UVB, so be sure to have your arms and face exposed.
