with the global climate and everything that's happening in the world today with viral infections
certainly you may have heard about the link with vitamin d deficiency and not doing so well with
a certain virus what drives me crazy is that nobody is telling you the causes of vitamin
d deficiency to begin with well today i'm going to let you know what they are and i welcome you
into my channel so if you're new to my channel welcome i'm dr janine bowring naturopathic doctor
and i would love for you also to subscribe to my channel give me a big thumbs up and stay tuned
right until the end of this video so what are the causes of vitamin d deficiency well number one
lack of sunshine yes it seems so simple but it really is something that we have to think about
and depending where you live in the world this has a lot to do with the latitude so certainly
the further away that we are from the equator what happens is that the zenith angle and this is what
it's called of the sun is now hitting the earth at a different angle and it's a lesser angle so
it's about 45 degrees the further we get away from the equator and this is typically the strongest at
noon time so in the summer time here i live in canada in the summer time i have that great
zenith angle it's about 90 degrees and that's why i get great vitamin d exposure from the sun and
my skin making that vitamin d naturally but the further away we get and the deeper into winter
that we get at these either northern or southern latitudes because of that zenith angle of the sun
our skin simply cannot make that vitamin d and that's why so many of us living in these parts
of the world become very deficient in vitamin d and it's the uvb rays from the sun that we need
on our skin to be able to make that so really in canada where i live from mid-october till about
mid-april i am not able to synthesize vitamin d on my skin another cause of vitamin d deficiency
is the use of clothing so even if i am outside in the summertime a lot of people are covering
up so we've heard all these myths about sun exposure and higher risk of skin cancer and
things you have to check out my whole other video all about the benefits of exposing our bodies
to the sun so make sure you check that out but also different cultures are covering their skin
because of their cultural clothing and simply not getting that natural sunlight exposure therefore
creating a deficiency in vitamin d another cause for vitamin d deficiency is sunscreen use so the
use of sunscreen is another problem so much like covering up because we're protecting ourselves or
maybe it's a cultural issue the use of sunscreen we're simply not getting that natural vitamin d
manufacturing in our skin another cause of d deficiency is poor absorption and this really
has a lot to do with the color of our skin so certainly darker skin tones need to spend a lot
longer time in the sun so it can take up to 90 minutes in the darkest of skin tones to actually
manufacture and start to manufacture that vitamin d from the sun fair-skinned individual so someone
like myself may take 5-10 maybe 15 minutes to get that natural vitamin d manufacturing on my
skin surface there are also certainly dietary deficiencies so vegetarians are notorious
for having a d deficiency from the diet because there are very few vegetarian foods that actually
have enough vitamin d and it's vitamin d3 that's most important that's the type that our skin makes
from the sun and the usually it's vitamin d2 from the food sources but i have a whole other video on
food sources for vitamin d so make sure you check that out and thank you for watching if this video
