Is Sun Exposure Really "Deadly" as the Media Would Have You Believe

Is Sun Exposure Really "Deadly" as the Media Would Have You Believe?  Or Can Regular Sunshine Give You a Better Body and Health?

-the sun's "deadly rays" or "healthy rays"?

One thing that never made sense to me over the years was how the media and other sources have always tried to portray sun exposure as "the sun's deadly rays". It's as if they would have you believe that we need to live in caves and never see the sun to prevent cancer and stay in good health.

But this is absurd if you think about it... the sun is THE provider of all life on earth. Without the sun, everything on earth would die.

Throughout the majority of human existence (with the exception of the last few decades), humans have always spent more time outdoors than indoors. Nowadays however, most of us are trapped inside offices all week long and might only get out into the sun once a week, if that.

I've been doing a lot of reading and research over the last couple of years regarding sun exposure, cancer, vitamin D levels, etc. This subject of the sun and natural production of vitamin D can fill entire books, so I'll try to summarize my opinions and what I've learned in the past few years through a lot of my reading.

Don't worry, I'm not ignoring the fact that overexposure to the sun CAN cause problems, including cancer... but we need to also consider the fact that underexposure to the sun can have problems as well. 

Let's look at a few points to consider:

1. Non-consistent sun exposure and infrequent SUNBURNS is the major cause of damage to the skin and increased risk of cancer... Think about your typical person that sits inside an office all week long without ever seeing the sun, and then gets FRIED at the pool or the beach on the weekend. THIS is where the damage occurs.

2. Regular consistent small amounts of exposure to the sun (without burning) can actually have a protective effect on the skin, increases healthful Vitamin D levels in the body, and can improve mood, help depression, and dozens of other benefits.  Each individual's skin pigmentation determines what amount of sun exposure they can safely obtain without doing more harm than good.

For example, a very fair-skinned person with a far northern heritage might only be able to get 10-15 minutes of sun exposure over the majority of the body during peak hours before it does more harm than good.  However, someone with darker skin and a heritage that originated closer to the equator might be able to get much longer periods of regular sun exposure without doing more harm than good.

3. Increasing Vitamin D levels from regular small doses of sunshine can actually decrease cancer risk. Vitamin D itself has been shown to have a protective effect through various processes in the body.

4. This one is interesting and deserves some thought -- According to Dr William Grant, a Vitamin D researcher, cancer rates in those living at high latitudes (farther north) such as Iceland are approximately 4 TIMES the cancer rates of those living at lower latitudes (closer to the equator) in the tropics. 

Hmm, yet those people living in the tropics are getting MUCH higher levels of those so-called "deadly sun rays"... but they are also producing higher levels of protective Vitamin D on average too.

5. Vitamin D is actually produced into a hormone in our bodies and regulates hundreds of processes in the body, and is WAY MORE important to almost every single aspect of your health than most people realize. There is even evidence that due to the regulation of so many hormonal processes in our bodies that can be affected by Vitamin D, producing enough Vitamin D in your body can even help with fat loss, muscle building, blood sugar control, and hundreds of other factors.

6. It is hard to obtain enough Vitamin D from dietary sources alone (egg yolks, organ meats, and fatty fish are good sources, but still relatively small). The best utilized source of Vitamin D is what we produce in our bodies from moderate regular sun exposure over large portions of the body without burning.  It's vitally important to note that the UV-B rays are only strong enough to trigger vitamin D production in your body between the hours of approximately 10am to 3pm.  Of course, this is the exact time that well-meaning, but uneducated "health experts" erroneously tell you to stay out of the sun. 

UV-B rays aren't strong enough in the early morning or late afternoon to trigger vitamin D production, so you must get moderate exposure over large portions of your body for small amounts of time (10-30 minutes depending on skin pigmentation) in the middle of the day to reap the benefit of Vitamin D production.

7. An antioxidant-rich diet can help to protect the skin (to an extent) from damage if you get too much sun exposure. This means that getting lots of antioxidants from things such as various teas (green, black, white, rooibos, yerba mate, chammomile, etc), various berries, fruits, vegetables, beta carotene, nuts, olive oil, etc, etc can help to protect your skin. Make sure to pick up some Prograde Longevity - a super high ORAC antioxidant blend that I take to help increase my antioxidant levels in the body.

8. Another point that proves that irregular burning is the major cause of damage and not regular small doses of sunshine... Rates of skin cancer are typically higher in areas of the body that get irregular sun and occasional burning as opposed to areas of the body that have received consistent sun for your entire life.

Notice how more cancer is often found on the back and chest (places that get irregular sun and more burning) vs the back of the neck or the forearms (which get consistent regular sun for most people our entire lives).  There are exceptions to everything, but this seems to be a common trend.

9.  I've come across studies over the last few years that indicated skin caner rates are higher among indoor office workers compared to outdoor workers. This is yet another interesting trend... it basically supports the conclusion that being underexposed to sunlight most of the time (working inside an office all week long) and then getting infrequent overexposure to the sun is a lot more problematic compared to an outdoor worker that gets regular daily sun exposure.

Of course, the indoor worker can always avoid this problem by getting outside for 10-20 minutes daily during breaks to get those protective small daily doses of sunshine that we've been talking about here.

10. Think about this issue in terms of common sense -- Don't you feel a heck of a lot better and more energetic when you've at least gotten out in the sun for 20 or 30 minutes in a day rather than being stuck inside all day?

So what's the best way to do this in a healthy way while minimizing sun overexposure risk?

a. In the winter in northern latitudes (above approx South Carolina latitudes in the US), your vitamin D levels may fall to dangerously low levels if you go for several months without getting any sun.  In winter, since your body will not be producing enough Vitamin D from the sun, you need to make sure to increase your intake in your diet... as I mentioned, fatty fish, egg yolks , and organ meats are some of the best dietary sources of vitamin D, but still generally don't increase your body's vitamin D levels that much.

I like to take a small amount of daily cod liver oil in the deepest months of winter to make sure my Vitamin D levels don't go too low. You also need to be careful not to take too much cod liver oil though as some scientists believe that excessive amounts of cod liver oil can give you overdoses of vitamin A. 

Also, the source of vitamin D used in VGF-25 whole-foods based vitamin is a good natural form of vitamin D derived from fish liver oil.  I would use this daily to make sure that your vitamin D levels are adequate, even in summer months, if you don't get daily sun exposure in the summer.

b. In the spring, try to start with just small periods in the sun such as 10-15 minutes/day over large portions of your body (not just your hands and face). The more skin surface exposed to the sun, the more vitamin D that your body will produce.  Make sure to try to NEVER get a sunburn!  Gradual small doses of sunshine over a large part of your body almost daily helps your body produce the most beneficial and protective Vitamin D levels. 

c. Avoid extended periods of overexposure to the sun on large portions of your body... If you're going to be out for several hours or an entire day in the sun, you'll still need to make sure to cover up appropriately (based on your individual skin pigmentation and sensitivity) to prevent burning and skin damage... remember that we're talking about regular small doses of sunshine that is beneficial, not entire days out in the sun without covering up.

Warning about sunscreens:

I would caution against relying heavily on chemical-based sunscreens as most of the chemicals used in sunscreens are potentially carcinogenic and are also known to be estrogenic, as they absorb through your skin and into your body.  If you're going to use a lotion based sunblock, you're best bet is a natural form that uses zinc oxide or titanium dioxide... These are natural sunblocks that don't absorb into your skin, but rather sit on top of the skin's surface and block the rays.  This is a big difference compared to the harmful chemicals that are in most sunscreens and can absorb through your skin (various benzones, homosalate, etc).  If you want to read more about the dangers of chemical sunscreens, this article will help.

d. Load up on antioxidant-rich foods such as various teas, fruits and veggies, berries, etc daily to help prevent free radical damage and protect your skin. 

I think one of the most powerful and synergistic antioxidant blends available is here  if you want some extra insurance on antioxidants.

e.  Lastly, I'm not a doctor, so many of the points in this article are my opinions based on years of reading and research. Make sure to consult with your doctor on your individual health characteristics and how this relates to sun exposure and vitamin D.

f.  Also make sure to read this article, as it shows a way to eat a nutrient for "internal sun protection" which can allow you to stay in the sun longer without damage to skin.
