Here’s a winter health fact. Our bodies need Vitamin D for many important processes including supporting the immune system, bone and muscle building, and to promote better sleep and mood.

We can even produce enough vitamin D ourselves. That’s if we bare our arms, legs, back, chests or faces to the sun for a limited period of time, because the sun’s UV rays produce Vitamin D in our bodies. Scientists reckon that five to 15 minutes, or five to 30 minutes for darker skinned people, of sun exposure two or three times a week will do it.
