Simple answer: We get Vitamin D from the sun. Vitamin D deficiency causes the immune system to stall out. People with sufficient Vitamin D supplies in their blood have a stronger immune system than those who don't -- and viruses are powerless against a strong immune function.
Twenty (20) minutes of unprotected sun exposure a day at peak sun hours is enough to keep your body manufacturing sufficient quantities of Vitamin D, and help keep you immune system strong.
I know, I know....this goes against everything the sunscreen manufacturers advertise and some doctors advise.....ever wonder why? Studies have shown that regular use of sunscreens and sunblocks prevent our bodies from naturally manufacturing enough Vitamin D to keep our immune function healthy.
We don't suggest you toss your sunscreens, but 20 minutes of sun on unprotected skin (arms and legs are usually more tolerant of sun) will help increase immune function. Sun-sensitive folks should shade sensitive areas (face, etc). Eating clean, organic foods, getting sufficient exercise and rest, drinking sufficient quantities of pure water, etc., will also help keep your body at top form and disease-free.
