Why this guide
Many people have spent years avoiding the sun and still feel exhausted, inflamed and out of balance. Dr. Hoffman's view is that the sun isn't the problem; we have lost the biological capacity to receive it. A solar callus is a gradual, deliberate build-up of melanin, the way a musician builds calluses on their fingertips.
