UVB Light: Why some exposure is so important for health

1 Comment

In this Health Edge podcast, John and Mark review a paper that reviews the many effects of UVB light on the skin and systemic neuroendocrine and immune systems. They discuss the importance of photobiomodulation and the health implications. For mind, mood, pain, and inflammation, our sophisticated skin and retinal chromophores are quantum portals to health in the presence of sunlight.

    Thank you for “shining a light” on the importance of sunlight exposure to human health, which topic was not on the radar screen at all or was misunderstood by me and probably most other people. I have some questions that I hope you will address in a future podcast.

    The title of the paper references systemic changes through skin and doesn’t reference through eye. But the article mentions “eye” 29 times. In the winter months in northern hemispheres, when daylight hours are short and people are bundled up, does it suffice to get the desired health benefits of sun exposure to go outside during daylight for some period of time without glasses or sunglasses?

    Mark, in your recent interview with Drew Pearlman, you said you use full spectrum lighting for 20-30 minutes every morning, not year-round but Columbus Day through spring at your northern latitude. (You also mentioned using infrared light at night but said that is for chronic back pain, not the systemic benefits referenced in the 2018 study.) Is it correct to infer from that you think being out in the sunlight without glasses or sunglasses in the winter months does not by itself suffice to get the desired health benefits? Also, it would be very helpful to know what source/brand you use for full spectrum lighting, as I and maybe others too are not familiar with this tool. This choice seems particularly important in light of (no pun intended) John’s statement that an imbalance in the wavelengths of light we’re getting causes mitochondrial dysfunction.

    In a long list of informative podcasts you’ve made over many years, this ranks right up there with those most helpful in leading me to make important and enduring lifestyle changes. Bravo, kudos, and thanks!

    Best regards,
    Marianne
