How to EMF-Proof Our Skin
Edible Sunscreen, IR & UV Light + How Pale People Can Build Their Skin
But if our natural skin complexion is pale, we have less melanin, which means that we don’t tan as easily.
What do we do?
How do we reap the benefits of the Sun, while making sure we do no harm?
The “experts” tell us to stay out of the Sun, citing studies that have only focused on UV in lab environments, while forgetting to take into account the total solar spectrum.
Building our solar callus (our tan) is wise for two reasons:
- prevents us from burning
- allows us to absorb more UV, creating more melatonin during the day:

Artificial blue light destroys melatonin in our eyes and depletes our dopamine, causing us to become more light-sensitive to the Sun the more we stay indoors.
On the other hand, the Sunrise has massive amounts of natural blue light, which wakes us up, but is also balanced with red and IR-A (infrared A) light:

The Sun We Can’t See
IR-A is the same as NIR (near infrared). NIR allows us to absorb subcellular melatonin.

More infrared = less red skin
Did you know that infrared light can provide up to a SPF 15 level of skin protection, if we receive this light before UV?
How do we get a healthy tan?
- Knowing when IR-A is present and when UV light is absent
- Pre-loading the skin with a ton of IR-A light.
- Loading the skin with a healthy dose of UV-A, followed by UV-B.
When we follow Mother Nature’s process, we surrender to common sense.
Why is this relevant for all you pale vikings out there?
Let me fil-a-ggrin the blank for you
Northern Europeans and those with a Fitzpatrick skin type of 1-3 have less melanin on our epidermis (outer skin layer). Melanin absorbs UV radiation, however these populations lived in areas with low UV, causing melanin to locate itself in deeper structures of the brain and central nervous system.2
As melanin was lost on our skin surface, the protein filaggrin (FLG) came in to fill its place. For some, the FLG gene underwent a mutation that would allow those with paler skin to absorb more vitamin D as their sensitivity to UV light was increased. 3
Red-haired people need red light
Filaggrin must be in skin to develop our solar callus, and is made by IR-A light.

IR-A light has a longer wavelength, and penetrates more deeply into our skin. Its longer wavelength is the same reason you see more red in the sky at morning vs. blue (shorter wavelength).
This is why space telescopes like Hubble are engineered to detect in infrared, as it is able to “see” deeper into objects and the infrared light energy (invisible to the naked eye) being emitted from stars:

In the second Hubble image, infrared light flows through the clouds, revealing a vast number of the stars both past the nebula and blazing to life within it. Note the bright, newborn stars now obvious in the tops of the pillars in the infrared image. The longer wavelength of IR-A, also referred to as the optical tissue window, allows this light to repair cellular damage and regulate the energy centers of our cells, the mitochondria.
Filaggrin is made by infrared light that stimulates cells called fibroblasts to make collagen for our skin.Tip: If you have brown spots (melasmas) on your face this could be a sign of excessive blue light with no IR-A and UV-A light, which stimulates melanocytes on the facial skin where there is very little fat present. This usually occurs on the skin above bony prominences.

UV: all the blame, none of the credit
Why is this important?
We use UV to make wonderful compounds like vitamin D, thyroid hormones, dopamine, melanin, melatonin, serotonin, and for all you pale vikings out there – urocanic acid.
Urocanic acid creates a type of UV filter from histidine:

As histidine in our bodies absorbs Sunlight, our skin makes urocanic acid that is a UV filter that protects us from sun burn and skin damage.
