    Hi Jerry!

    Rest easy. The sun can and does do damage. RLT therapy does not - it is not ultraviolet light.

    Ok..I hope this helps:
    Sunlight contains ultraviolet radiation, visible light and infrared radiation. The colors that compose sunlight are known as visible light. If you remember from science class: roy g biv are the colors of the rainbow. Red light has the longest wavelength as opposed to violet light which has the shortest.

    **At the violet end, we have Ultra Violet light (shorter than violet) and is not visible to the eye although I believe birds and bumble bees can detect UV light.

    **On the red end, we have Infra Red (longer than red) is also not visible to the human eye.

    Everything in between is considered visible light and can be perceived by human vision. The bookends, UV and IR, are on opposite ends of the electromagnetic spectrum with visible light being in between.

    Consider Red light therapy to be compressed light from the red and infrared spectrum. Red light is visible. Infrared is not visible. Because of the wavelength, the red light is easily absorbed by the skin because the tissue contains water and blood and can penetrate deeply into the tissue. Infrared can penetrate farther because of the wavelength. The longer the wavelength, the farther it will go. Ultraviolet light wavelengths are short and somehow break what bonds the skinís tissue together. Burning or tanning is the natural response to the skin being exposed to UV light.

    There are basically 2 types of Ultraviolet light: UVA and UVB: UVA is the same strength all year long no matter where you are on the planet and it easily goes through glass. I would imagine this is what fades the carpet and drapes in your hosue. UVB is stronger in the summer months, especially between 10-2 and does not penetrate glass. I believe that Infrared light does not penetrate glass either.

    Does this makes sense??

    yes it does make sense, i think, wait, let me re read, Ok yes, I got it, wait. Just kidding with ya.
    For those not familiar with the roy g biv deal, its aslo how I learned the colors of the spectrum.
    Red, orange, yellow, green, blue, indigo. violet. there are dirty ways to remember this, but I will behave.
    Some have posted here that early morning sun, or evening sun helps their face, and I am guessing that is because of the light spectrum. Just a guess here

    Kind of stupid in a South Park kind of way I know, but we were just kids after all (long before South Park came along though)
