Natural health expert and founder Dr. Joseph Mercola interviews Alexander Wunsch, a German physician of holistic medicine and photobiology, about the healing power of sunlight.

Read Dr. Mercola’s article:

  • Humans are adapted to sunlight as a complex stimulus that helps keep your body healthy. Exposure to the 1500 wavelengths in sunlight enables your body to react in a balanced and beneficial way
  • Red light has been successfully used to treat age related macular degeneration, knee osteoarthritis, cold sores, hypothyroidism, cognitive dysfunction following brain injury, cellulite, hair loss, and fibromyalgia
  • Blue light has been successfully used to treat acne and antibiotic-resistant bacteria such as MRSA; full spectrum white light increases blood flow and antibody production, and decreases inflammation

Without the sun there would be no life on this planet, and your body needs sun exposure for optimal health as well. In fact, the sun can be a great healer, providing benefits that go far beyond vitamin D synthesis.

As noted by photobiologist Alexander Wunsch, humans are adapted to sunlight as a complex stimulus that, at the appropriate dosage, helps keep our biological systems running.

When we talk about sun exposure to optimize vitamin D production, we’re really only looking at a small portion of the action spectrum of light, because ultraviolet B (UVB) radiation is the only portion able to photosynthesize vitamin D in your skin.

However, sunlight contains many other wavelengths, and we’ve likely only scratched the surface when it comes to identifying the biological activity influenced by the various portions of the sun’s light spectrum. . . . (read the whole article)
