Well summer does seem to be here doesn’t it? One day of sun and a thunderstorm! It’s all good – nature needs both and frankly, so do we. The sun gives us huge amounts of vitamin D3 amongst other things.
I am still largely opposed taking supplements of vitamin D3. I have written many times about the problems with taking supplements and maintain my stance. Buying them is fraught because we don’t know how they have been made or whether they contain what they are supposed to contain and even if they do, whether it’s in the right form for humans to absorb! It is just too costly and complicated
We need the sun for our lives
Let’s take the benefits of the sun. Everyone knows that the sun makes vitamin D3 in our skins. Just think about that for a moment. Isn’t it absolutely astounding? This is just one example of how we are dependent upon our environment. (There are many others but I’ll save them for another time.) We need the sun for our lives – literally in every sense. We cannot survive without it and we become sick if deprived of it. We would not be here without the sun – and neither would anything else. It is vital that we appreciate and accept this fact. Our to-date evolution, over hundreds of thousands of years has depended upon the sun more than anything else. Most other factors in life have alternatives or can be foregone for a while.
..we have an epidemic of diseases associated with vitamin D deficiency
There is much evidence that certain diseases are more prevalent the further north in the hemisphere one looks. But we have lived in these places for many thousands of years and these diseases were not prevalent in our ancestors. “Modern” diseases are to be evidenced from remains that are less than 10,000 years old – giving grounds for the popular belief that these illnesses started during the time when we became farmers and had more permanent forms of shelter. Personally, I doubt that many of these illnesses were due to lack of sun exposure – we were very much outdoor people at this time. Their health change was more to do with their rapidly changing diet but as time continued, even more permanent buildings were constructed and much work was done indoors.
Even in the last couple of hundred years or so, we spent much time outside – walking (to get from one place to another, not necessarily for pleasure), farming, gardening and doing all those other necessary jobs that involve us stepping outside the house. Not anymore. Bringing it bang up to date, we travel to our place of work by car where we then enter an artificially lit, windowed building which allows no UVB light to enter. We travel home by car and spend the rest of the day inside. For many, the main source of UVB light is once a year on holiday. And then what do we do? Smother ourselves in sunscreen! We are in real trouble. Now, here in the northern hemisphere, we have an epidemic of diseases associated with vitamin D deficiency – and it is true – the further north you look, the more of these diseases you find.
How we obtained our vitamin D through pre-history
If you accept that we originated in Africa about 100,000 years ago and migrated northwards, you will also understand that at this time our skins were dark which protected us from the relentless equatorial sun whilst still allowing us to obtain the benefits. The northward journey took time – no jumping on Easyjet and arriving a few hours later! It possibly took thousands of years to inhabit the most northerly areas. Remember that at this time the Asia and Europe we know now, didn’t exist and the countries were merged making the migration easier.
As we very gradually moved northwards, our skins lightened. Why do think that was? In order that we could still benefit from the now much weaker and less reliable UVB rays from the sun! Our skins had to lighten in order to scavenge these less frequent rays at a much quicker rate than our African cousins – and the further north you live – the paler your skin will be and the faster you will get your dose of vitamin D! So, given that we need the same levels of vitamin D, the same amount can be obtained in just a few minutes if your recent ancestry is Scottish, a bit longer if you’re English but much longer if you are dark-skinned and living in Africa!
Vitamin D3 is not really a vitamin. It is a pre-steroid hormone and as such, can affect your DNA (unlike true vitamins). My take on this, is that many of the diseases that we label as genetic may in fact be acquired. Chronic vitamin D deficiency can be passed to our offspring. I have lots of reasons for believing this but one factor that I have come across many times when I am asking people about their health, is the “Welsh Tale” as I have named it. If someone has several generations of miners in their family, there is more risk of disease in that person. I’m sure you get the connection. Another scenario which is well documented is that of recent immigrants (within a few generations) to the northern hemisphere. It is this group of people who are the sickest in the western world – more diabetes, heart disease, obesity etc. Whilst there is a dietary factor, there is also a lack of vitamin D from the sun. Life is indoors and even if some time is spent in the sun, it is rarely enough for vitamin D to form. Each generation does seem to have lighter skin even if both parents are dark-skinned – nature knows what has to be done, but this takes time.
To prevent vitamin D deficiency, we must sunbathe. It must be taken like medicine. If the sun is high in the sky and your shadow is shorter than you are tall, the UVB rays are reaching Earth. Depending on your skin colour, sunbathe as near to naked as possible for as long as it takes your skin to go pink. Not red. When this has been achieved, cover up, use sunscreen (try to find a non-toxic one or use coconut oil which offers a little protection) or go indoors.
Don’t use soap/shower gel for at least 24 hours as this will remove the skin oils that contain the vitamin D. Use just water on the main parts and maybe just a little soap where you feel you must. Moisturise your skin with something natural such as coconut oil. With this amount of sun exposure you can make up to 20,000 IU of vitamin D but your body will stop the manufacture when it has sufficient to deal with. This takes 24 – 48 hours – then you can go out and make some more! You won’t find this quantity in a supplement and indeed, if you took this amount, it would be harmful.
Since the fat-soluble vitamins work together, make sure you get plenty of vitamins A and K2 as well. Cheese is a good source especially Brie and Gouda.
Vitamin D is just one reason why we need the sun but there are others. For example, there is evidence that we need it for energy – just like plants. Lots of people feel energised when in the sun. Also, UV light through our eyes regulates our Circadian rhythms, thus helping us sleep. There will be more evidence to come I feel quite sure. Here is another article about the effects the sun has on us.
I have written about it before, but for completeness, I will give you a run-down of the diseases that seem (research is showing) to be related to vitamin D deficiency: around twenty types of cancer; diabetes; depression; heart disease; bone abnormalities; auto-immune diseases; infections.
