Why The Sun is Not Bad For You

Your body needs enough sun to get the benefits of vitamin D and feel energized.

Being in the sun is essential for your health, as you will learn by reading this post.

Many fear the sun as see it as something you should avoid at all cost. Asian countries like Japan and South Korea see tanning as low class. Farmers back in the day had darker skin by being outside, while the paler upper class stayed indoors.

We forget that humankind was once out in nature every day and got enough exposure to sunlight. In today's society, many people live inside most of the day and don't get enough sunlight.

The government tells you that being in the sun can cause skin cancer. But what you will read now will destroy all such claims.

The Incredible Health Benefits Of Vitamin D from The Sun

Sunlight increases the brain’s release of a hormone called serotonin. Serotonin boosts the mood and helps you feel calm and focused. Without enough sunlight exposure, a person’s serotonin levels can get low.

Low levels of serotonin can create a higher risk of seasonal affective disorder (SAD). SAD is a form of depression that triggers by changing seasons. It usually happens during the winter when there is less sunlight.

The sun is beneficial for cancer

The skincare industry has misled the public into believing that any UV exposure is harmful. No research show that regular, non-burning exposure to UV-light poses risk of skin damage.

If you sunbathe in with moderation, being in the sun is good for you and has many health benefits.

The Benefits Of The Sun

  • Boosts the immune system
  • Reduces the risk of cancer
  • Produces vitamin D
  • Creates strong bones
  • Good for the heart

How Low Levels Of Vitamin D Lead To Disease

Adequate vitamin D is as important as calcium for maintaining bone health. You can make all vitamin D when you expose your skin to ultraviolet rays from sunlight.

Low vitamin D levels can cause fibromyalgia, rheumatoid arthritis, multiple sclerosis, depression, muscle weakness, diabetes, hypertension, and cancer.

To avoid these problems you need to know how to maximize vitamin D.

If you don’t follow the directions I give you now, then you can’t get benefits from vitamin D.

The Secret To Boosting Your Vitamin D

The UVB-rays create vitamin D in your body. The UVB-rays only enter the atmosphere when the sun reaches 35 degrees from the horizon.

As the sun climbs the rate of vitamin D goes up until it reaches the top position called solar noon. The UVB rays usually enter the atmosphere between 10 am and 3,30 pm.

If you don’t get enough vitamin D from the sun, you can experience many problems. So if you believe that you have low levels of vitamin d, then read the next section.

The Difference Between Ultraviolet Rays

UVA-rays: Constitute 90-95% of the ultraviolet light reaching the earth. They have a quite long wavelength of 320-400 nm and are not absorbed by the ozone layer.

UVA light penetrates the furthest into the skin and begins suntanning. Overexposure to UVA suppresses the immune function and cause premature aging of the skin.

UVB-rays: The ozone layer absorbs some of the rays that have a medium wavelength (290-320 nm). They do not penetrate the skin as far as the UVA rays do and create vitamin D.

UVC-rays have the shortest wavelength (below 290 nm). And are almost absorbed by the ozone layer. UVC-rays can contribute to sunburning and premature aging of the skin if the ozone layer is thin.

Once the sun reaches below 35-degree the UVB-rays stop reaching the atmosphere. The sun's UVA-rays still enter the atmosphere during the afternoon or morning.

Your Body Usually Produces Vitamin D Between 10 am- 3 pm

The UVA-rays penetrate deeper than UVB-rays. Overexposure to UVA-rays can damage the skin. If you sunbathe before, 10 am or after 3 pm you miss out on UVB-rays and don’t get any benefits of vitamin D.

Besides the solar angle, the location you reside affects the amount of vitamin D you can get. If you live 35 degrees latitude or less from the equator, you can get vitamin D every day of the year.

If you live further away from the equator, you can only get vitamin D part of the year.

All the tips I gave you now is completely useless if you don’t know what hinder vitamin D production. So follow these guidelines, and you won't have any problem.

Things That Hinder Vitamin D Production

Clothes can block vitamin D generation. The more areas of the body that you expose to the sun the higher the rate of vitamin D.

Your skin color influences the amount of vitamin D that you can absorb. The darker the skin, the less vitamin D you will generate.

The lightest skin pigment creates six times more vitamin D than the darkest one. Age affect Vitamin D absorption. A 70-year old has a 70% reduced ability to produce Vitamin D compared to a 20-year old.

Obesity can hinder vitamin D intake. Fat cells store vitamin D and make it less available to the rest of the body. This lead to a higher need for it.

Sunscreen or clothing over the skin won’t result in vitamin D production. Neither does being behind glass because it filters out most of the UVB-rays.

How to Get Vitamin D If You Live Far Away From The Equator

The further away you live from the equator, the less chance you have of making vitamin D during the winter. Residents in the northern parts of America can make vitamin D in the spring, summer, and fall months. But can’t get any UVB-rays between November - March.

Earth From Space

Part of the world becomes vitamin D deficient during winter

If you live in Scandinavia, you can’t produce Vitamin D from the sun between late September to March.

Try going on a sun trip during the winter if you live in a place with less sun.

But what happens if you don’t have sun exposure are there still a way for you to get vitamin D? If you have this dilemma then what I tell you next will answer all your questions.

How to Supplement with Vitamin D

The sun is the best source of vitamin D. Vitamin D is not a regular vitamin. It's a steroid hormone that you get from either sun exposure or supplementation.

Food containing vitamin D is limited. The only sources of vitamin D in foods are fatty fish, eggs from chickens or mushrooms treated with ultraviolet rays. Eating animal foods create acidity in your body and is not a good source to get vitamin D.

Milk contains no vitamin D unless fortified. It’s not a more natural source of this vitamin than other fortified food.

There are two types of vitamin D used in fortified foods and supplements, Vitamin D3 and D2. Vitamin D3 comes from animals, usually from sheep’s wool or fish oil. But there are vegan options as well.

Vitamin D2 is usually obtained from yeast and is vegan. There is a debate going on whether D3 is better than D2. Both two get absorbed equally well. ​So you can ​use the one you like and will reap the same benefits.

Supplementing with D2 and D3 should be your last resort when you're vitamin D deficient. Get it from the sun if possible. 

Before you supplement, it’s useful to test your vitamin D level. There is a particular test you need to take to know if you’re deficient. Luckily I’m going to explain it now.

How To Test Your Vitamin D Level

The best way to get vitamin D is through the sun. Our ancestors didn’t take pills to be healthy, they stayed in the sun and didn't get a deficiency. The lack of vitamin D in today’s society has more to do with our lifestyle.

Michael F. Holick is the top expert on vitamin D, having more than 30 years of expertise in this area. He is an American endocrinologist and professor of medicine at the Boston University.

In a lecture that Dr. Hollick gave, he said that best way to create vitamin D in the body is from the sun´s UVB-rays. The best blood test to assess vitamin D status is 25 hydroxy D.

He said to be healthy you want your 25 hydroxy D level to be between 30-60 ng/ml or higher. Dr. Holick believes that most people should be supplementing with a minimum of 1000-2000 IU of vitamin D per day.

​If a person is vitamin D deficient, then they may need to take 2,000 to 3,000 IU of vitamin D a day. 

A person who is severely vitamin D deficient should consult a doctor to get even higher doses.

The big question still is, does the sun create cancer? What you'll read about now will shake up your negative beliefs about the sun.

How Vitamin D Reduces Cancer Risk

Many studies show that vitamin D has a positive effect on cancer. Women with low levels of vitamin D are more likely to develop breast cancer, according to a review study.

The sun has a healing effect

In a study 2005, they investigated the vitamin D and serum intakes in colorectal cancer. A daily intake of 1000 IU or more caused a 50% lower risk of colorectal cancer.

A scientific article found 63 observational studies of vitamin D and cancer risk. These included several studies of colon-, breasts, prostate- and ovarian cancers.

They found a protective relationship between enough vitamin D and lower cancer risk. Furthermore, they said that supplementation could reduce cancer incidence and mortality at low cost. With few or no adverse effects.

Vitamin D Is Beneficial For 15 Types of Cancers

In 2012 scientists studied the cancer incidence in more than 100 countries.

They found a high correlation with UVB-vitamin d for 15 types of cancers.

They concluded that:

The evidence for the UVB-vitamin D-cancer hypothesis is very strong in general and for many types of cancer in particular.

Cancers in the brain, gallbladder, laryngeal, oral/pharyngeal, prostate, thyroid leukemia, had weaker evidence.

A PLOS ONE study examined the vitamin D level in women.

Women with vitamin D concentrations of 40 ng/ml or greater have a 67 percent lower risk of cancer. Compared to women with levels of 20 ng/ml or less.​

Sunbathing in moderation is beneficial for your health

The medical establishment sees the sun like an enemy. But it’s clear from all scientific evidence that the sun has a positive effect on cancer.

If you sunbath in moderation then it's an excellent way to protect against disease.  

Before you can use vitamin D to fight cancer, you need to know why you should avoid sunscreens. 

Ignoring this fact make everything I taught you now useless. So pay attention to what I’m going to tell you.

Why You Should Avoid Sunscreens At All Cost

The rate of new melanoma tripled in American adults since the 1970s. Despite the use of sunscreens. From 7.9 per 100,000 people in 1975, to 24 per 100,000 in 2013.

A study published in the American Journal of Public Health examined the melanoma incident. They said that:

In the United States, Canada, Australia, and the Scandinavian countries, melanoma rates have risen steeply in recent decades, with the greatest increase occurring after the introduction of sunscreens.

There are two types of sunscreens:

  • Chemical sunscreens usually contain a combination oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate. They prevent sunburn by absorbing the UVB-rays.
  • Mineral sunscreens contain titanium dioxide, zinc oxide, and talc. They reflect the ultraviolet rays away from the skin. Oxybenzone is a common UV-filter in sunscreens. It is a hormone disruptor and allergen.

The EWG warns against using oxybenzone, especially on children or pregnant/breastfeeding women. It’s added to about 70 percent of the non-mineral sunscreens.

Mineral sunscreens use zinc oxide or titanium dioxide. Many products combine zinc oxide with chemical filters.

According to Wellnessmama:

Of the 1,400+ sunscreens tested by the EWG, only 5% met their safety standards and over 40% were listed as potentially contributing to skin cancer.

If that made you shake your head, then what I’m going to tell you now will make your stop using sunscreens.

Warning! Sunscreens Block Out Vitamin D

Using lotions or other creams inhibits you from noticing your body's warning signals. Which make you make you be longer in the sun than you ought to be.

Sunscreens block out most vitamin D.

If you cover your body with sunscreens, you become vitamin D deficient. Even if you're on vacation in a warm country and out in the sun every day.

Sunscreens block vitamin d and contain harmful chemicals

Sunscreens aren't needed if you use common sense. If the sun is too intense, then hide in the shade, wear clothes that block UV-rays or use a hat that protects your face.

Your body will tell you when you had enough sunlight by giving signals. Don't try to be in the sun more than your body tells you.

How long can your be in the sun before it’s too much? Let me share a story when I stayed too long in the sun and what I learned from it.

Can Too Much Sun Be Bad For You?

Getting too much sunlight can have adverse effects on your body. But so does eating too much healthy food or drinking water, even if you know that these things are good for you.

If you follow your body’s signals, sunbathing without sunscreen should not create any problems.

I made the mistake of being in the sun too long once. I didn’t wear any sunscreen and knew that I had to get away from the sun, but I ignored my body’s signals. When I came home, I didn’t feel well and got a fever.

The day after I felt frozen and weak. I didn’t have to experience all this if I had followed my body. Now I’m more careful and hide in the shadow when I feel that I got enough sunlight.

By following this regimen, I can get vitamin D but not risk burning my skin even if I don’t wear any sunscreens.

Be cautious to spend too much time in the sun the higher the UV-index is. The ultraviolet index or UV Index measures the strength of sunburn-producing ultraviolet (UV) radiation.

The closer you´re to the equator the higher the UV-index. Just remember that the higher the UV, the shorter you can be in the sun before you become sunburned.

Let us summarize what you learned today

Summary

The best way to get vitamin D is through the sun.

Vitamin D can protect you from many diseases, including cancer.

There are two types of vitamin D used in fortified foods and supplements, Vitamin D3 and D2.

The UVB-rays create vitamin D in your body.

The UVB-rays only enter the atmosphere when the sun reaches 35 degrees from the horizon.

Sunscreens block out vitamin D and can cause cancer.

The best blood test to assess vitamin D status is 25 hydroxy D.

Your 25 hydroxy D level should be between 30-60 ng/ml or higher

So now that you know the beneficial effects of the sun. Let’s take some action and make use of what you read about today. Follow these simple steps.

How To Boost Your Vitamin D and Reduce The Cancer Risk

2. Take a 25 hydroxy D test to check your vitamin D level

3. ​Go outside between 10 am - 3.30 pm when the UVB-rays are at its peak

4. Spend 15-30 minutes outside in the sun at the given hours mentioned above

5. ​Avoid using sunscreens

6. Stop being in the sun when your body says so​

Action Steps

To make everything easy for you, I’ve createda free guide that you can download here. Use this handy guide to get actionable steps on what you learned today and some bonus tips that you will love.

The first step in knowing if you’re vitamin D deficient is to take a test. The 25 hydroxy D test is the most reliable test. Google "25 hydroxy D test" and find homepages where you can order it.

Try to get outside between 10am -3.30 pm when the UVB-rays reach the earth. If you miss out on being outside during these times, you lose your chance to get enough vitamin D.

​Expose as much skin for faster vitamin D production. 15-20 minutes per day can often be enough.

Avoid using sunscreens as they can contain harmful chemicals and block out vitamin D. Sunbath in moderation and stop exposing yourself to the sun when you feel you had enough.​

Wear a hat or put on more clothes to protect from sunburns when you’re have reached your limit.
