Holistic UV Exposure is a topic I also mention in my new book: “VISION & Holistic Health.”

There are numerous benefits to ultraviolet (UV) exposure, but like most things: “moderation is key!”

One analogy I think is appropriate is food. Too much food consumption, especially too much food consumption over long periods of time can lead to premature death due to a multitude of reasons, including diabetes, cardio-vascular disease and cancers.

Similarly, Sunlight / UV exposure is vital for our health in mild to moderate doses. But, too much can lead to premature aging, cancers and death.

We need to self-regulate our exposure to UV in mild-to moderate doses, preferable on a daily basis, for several minutes a day, including sun exposures at different times of the day: morning, afternoon, and early evening, because the component wavelengths of sunlight are different at various times of the day.

These “sun breaks” can just be a few minutes each, like 5 to 10 minutes.

During those breaks it is best not to wear UV
protected eyewear/sunglasses, or sunscreen.

The Earth’s atmosphere changes the appearance of sunlight emitted across a range of wavelengths, which change throughout the day. The exact appearance of sunlight can vary depending on factors like location, weather, and the season. But generally, these are the changes in sunlight you can observe during the day.

During the Morning: The sunlight after sunrise tends to be cooler and crisper, which means it has more blue light.

During midday: when the sun is high in the sky, the light is more intense and contains a balanced mix of different wavelengths.

During later in the afternoon: As the day progresses towards the afternoon, the sunlight often appears warmer, with more yellow and red light.

During sunset: the sunlight has to pass through even more atmosphere, which filters out most of the blue light and leaves the sky with beautiful shades of orange, red, and pink.

Other than humans, there are no other animals that put on sunscreen, wear sunglasses or wear special sun protective hats. We need to do, as many other animals do, which is to spend some time in the sun, but know when to get in the shade!

We need to self regulate!

Mild to moderate UV exposure is critical to our Vitamin D synthesis, production of serotonin to positively affect our emotional well-being, and production of melatonin to help with improved sleep quality.

But, if you strictly follow “mainstream” recommendations from otherwise very reputable organizations, you would never have ANY
UV exposure!

Following with my food analogy, that would be as ludicrous as organizations saying to stay away from any form of food.
We need food. We just don’t need excessive food!
Similarly, we need sunlight / UV exposure; but we don’t need excessive amounts!

Seasons and Latitudes affect the
intensity of sunlight & UV exposure.

UV Rays Are Stronger:

1.during the spring and summer months

2.closer to the equator

3.At higher altitudes

Note: Snow, sand and water can reflect UV
radiation, causing increases in UV exposure

Most skin cancers are caused by excessive exposure to ultraviolet (UV) light. UV rays come from the sun, tanning beds, and sunlamps. These rays can damage skin cells and increase the risk of skin cancer. UVB rays pose a greater risk of skin cancer, while UVA rays contribute to aging, wrinkling, and loss of skin elasticity.

A key concept in understanding the importance of proper lighting in our lives, is this:
