Does Lack of Sun Effect The Immune System?

Our body works in synergy with the Suns UVB ultraviolet rays to produce vitamin D3

The Sunshine Vitamin

Sunshine and your immune system work together in synergy, naturally producing vitamins such as vitamin D3Β  produced from the synthesis of UVB radiation from the suns rays and the cholesterol in your skin.

There are actually 2 types of Vitamin D

Vitamin D2 that can and is easily sourced via plants.

Vitamin D3 produced natural y with the help of the Sun or sourced from animals and dairy.

D3 is an essential vitamin, it is multi functional across many spectrum’s of the immune system and your body.

Being deficient in this particular vitamin can cause serious problems to your health, your development and overall well-being.

Most of Us Will Find That We are Seriously Lacking in this Exceptionally Important Vitamin.

Correct amounts are regularly required to support among other things, muscle function, bone and tooth development, it also enables your body to absorb calcium and phosphorus and has actually been linked to brain health.

Vitamin D3 Keeps You Sharp
Studies have shown that low Vitamin D3 levels are association with Cognitive Impairment and Dementia.

Vitamin D3 is one of the vitamins we are able to produce ourselves naturally, production is initiated when you are exposed to the sun.

The suns UVB rays interact with the lipids, otherwise known as cholesterol (fats) in the uppermost layer of your skin, to produce vitamin D3.

D3 is one of the most essential vitamins your immune system needs to function effectively and efficiently.

However, there are drawbacks to getting the right amounts of vitamin D3 this way even if you do live in a country that has wall-to-wall sunshine throughout the year, the major drawback being skin tone.

A Word of Warning

Please be mindful that wearing sunscreen is a must in the sun, but you also need to be aware that it blocks both the ultraviolet A (UVA) rays and ultraviolet B (UVB) rays from the sun.

It is the UVB energy that provides the energy your skin needs to make vitamin D3, but that energy can burn the skin and cause cell damage that can lead to cancer.

UVA as well as contributing to skin damage also causes premature aging so it is advised that sun protection is worn at all times whilst out in the sun no matter what your skin tone.

Does Skin Color Have An Impact on the Ability to Produce Vitamin D3 this Way?

Yes, very much so, there are major drawbacks to getting the right amounts of vitamin D3 via the sunshine alone even if you do live in a country that has wall-to-wall sunshine all year round.

The biggest drawback being skin tone, skin tone which is usually darker in hotter climates contain a pigment called Melanin which gives skin its beautiful color.

Melanin absorbs the suns ultra violet rays that initiates vitamin D synthesis significantly inhibits the skins’ ability to produce levels that ensure robust immune system health.

This in itself makes it almost impossible for people with skin tones ranging from very light brown to very dark black skin due to the presence of Melanin so there is very little chance if none at all of producing sufficient daily amounts of vitamin D3 by sunshine alone.

Skin Color Makes No Difference on the Northern Side of the Hemisphere.

Vitamin rich-food
A varied and balanced diet, full of nutrients is important no matter where you live.

Skin color bears no significance in countries that can go without sunshine for up to six months a year such as.

If you live in the Northern Hemisphere where the winters colder, the days shorter and the nights longer it is literally impossible for you to produce enough vitamin D3 naturally through sunlight alone.

Vitamin D2 on the other hand is fairly easier to obtain as it comes from plants like mushrooms grown in UV light, fortified foods and dietary supplements.

Vitamin D3 comes from animals like oily fish, liver, egg yolks, butter and dietary supplements. (Mitch recommends)

You can ensure you include vitamin D3 rich food into your diet, but this is still rarely enough to ensure you are maintaining the correct levels.

Short days & long nights makes it almost impossible to produce any vitamin D3.

Should I Consult My Doctor Before Taking Vitamin Supplements?

Supplements are sold without a prescription and can be easily brought because of this I would strongly recommend you do your own research and due diligence, seeking advice where and when appropriate.

If you have any underlying health conditions, taking any prescribed medication or already taking vitamin supplements you should always seek advice and guidance from your doctor or health worker.

This is really important because some supplements can cause serious side effects if not taken in the right dosage, so please always seek medical advice.

    Hi Mitch, fascinating article. At the moment, we hear so much about Vitamin D, especially in the times of Covid 19. Our immune system needs to be strong. I live in the Netherlands, and even in some summers, we don’t have enough sun. Oily fish has a good amount of Vitamin D 3, but I wouldn’t like it to eat everyday fish. When I was a child, we have been punished with fish oil to build a strong spine. I hated it! But it is really a great supply if our oceans were not that polluted.
    Did you hear about Vitamin K2 be taken with Vitamin D3?

      Hi Sylvia πŸ™‹πŸ½β€β™€οΈ

      lol, yes I remember being given cod liver oil of a spoon…ugggg!!!😣

      But its so important to make sure we get enough of the D’s, Vitamin D3 in particular.

      I already know I have a deficiency so I make sure I take a daily supplement, I also make sure I get my oils, Omega 3, 6 and 9 all in one handy capsule so much easier.πŸ˜‰

      I hadn’t heard about the Vitamin K2 & D3 so I took a look, a great combination that work in synergy to improve bone development and cardio vascular health will take a further look at that so thanks.

      & Yes it is so very sad, my heart bleeds for our oceans and the amazing life that lives in it right now.

      Thanks for taking the time to join the discussion Sylvia, your comments and suggestions are encouraged and will always be appreciated.

      Hope to see you soon.
