Seems like every status we read on Facebook or Twitter refers to sickness. They seem fatigued, worn out, and just basically “under the weather”.

Well, our bodies were designed to produce an essential nutrient, but we need the sun for this. With the cold, we may not get outside as often. Another reason is the sun’s distance from us for the winter season. So, our bodies aren’t producing as much Vitamin D3 as it could. Our bodies can’t produce this without the help of UVA and UVB Rays. Our vitamin D levels can actually drop by 50% in the winter.
