Winter Solstice and Vitamin D

The Winter Solstice is rapidly approaching for those of us who are living in the northern hemisphere of the world.

What extra health concerns do we need to be aware of during this time of year?

The busy times with midterms for those of us in school, it always seems extra busy in the workplace too!


Everyone wanting to finish the year strong, gets people into a big rush to get things done.

There always seems to have other stresses during this time of year to the Holiday season affects people differently, and many have vacations that they need to take or the will lose it, just adding to the pressure.

But, the most significant effect to the Winter Solstice is the lack of sunlight and the reduction of Vitamin D that is available to us.

Vitamin D is crucial to the body in helping to keep our bones, teeth and muscles healthy. It also helps to regulate the amount of calcium or phosphate in the body, which prevents all sorts of bones related issues.

Symptoms of Vitamin Deficiency Adults

People who experienced Vitamin D Deficiency are going to be at a higher risk of getting sick.

They can experience a lack of energy, feel fatigued, have headaches, and catch colds or the flu more easily.

Some people feel it in their bones, and it can manifest as pain in the bones or the lower back area.

They are showing signs of depression or bad moods with no apparent reason.

Low Vitamin D levels will impede the body from healing itself and cuts and bruises will heal slower.

Depending on the length of time that the deficiency persist it can lead to bones loss, especially in older people.

It can also contribute to hair loss and muscle pain.

Causes of Vitamin D Deficiency Adults

Lack of exposure to natural sunlight; if you are always covered when out in the sun, either by clothing or sunscreen, your body’s ability to make the required amount of Vitamin D is limited.

The risk is higher for people who are on diets restricting the natural sources of Vitamin D, which come from animal-based food sources like; fish, eggs, fortified milk, etc.

Question Mark

The darker the skin on a person also affects how much Vitamin D it can produce. Something to consider when thinking about analyzing your health.

Kidneys must function correctly for the body to convert Vitamin D to its active form, reducing the amount of Vitamin D that is available.

Our digestive system must be working correctly for Vitamin D distribution throughout the body as well, which applies to all vitamins and minerals.

Body weight does affect the risk of becoming deficient in Vitamin D because the fat cells extract Vitamin D and prevent it from being circulated in the bloodstream.

Signs Vitamin Deficiency Adults

If you are experiencing any of the following signs and symptoms:

  • Fatigue and tiredness all the time.
  • Bone or Back pain for no apparent reason.
  • Depression without cause.
  • Notice wounds healing slowly.
  • Bone Loss or pain.
  • Hair Loss
  • Muscle Pain
  • Increased Blood Pressure

A Vitamin D deficiency can cause these. It is not the only thing that can cause these symptoms, but many people will overlook the possible connection between vitamin deficiency and these types of symptoms.

Treating Vitamin D Deficiency Adults

There is blood test available to test for vitamin levels in your blood. It is worth it to get tested.

Even if you are not experiencing any of the symptoms listed above, the test will let you know where you stand and what type of supplement you need.

If you’re living in the far northern latitudes at this time of year, a vacation to a place where the sun is shining may be a treatment that you can do for yourself.

Some other benefits can come from that type of “treatment” trip, especially if you like the summertime conditions and need a break from the cold.

For many of us that is not an option, but we can make up the deficiency in vitamins with a good vitamin supplement.

It is better to play the odds-on vitamins and take a good supplement that has all the vitamins and minerals the body needs, regardless of the time of year.

That is not necessary for all, and it may be as simple as taking a supplement with just Vitamin D. Something to consider!


Having darker skin, being elderly, being overweight or obese, not eating enough fish or dairy, living far from the equator where there is little sun year-round, always using sunscreen when going out, or just staying indoors.

All these conditions are indicators of being at risk of becoming Vitamin D deficient.

It is vital that if you find yourself in any of these conditions to talk to your Doctor if you start experiencing any of the symptoms of Vitamin D deficiency.

They can get the blood test ordered and find out what the issue is.

Thanks for taking the time to read my post and please leave any comments or suggestion on how to deal with the shortest daylight hours for those of us in the northern hemisphere.

    This is a great article.  Thanks for giving information about Vitamin D.  I might check into that, because I suffer from some of those symptoms.  I don’t get very much sunlight and I do feel fatigued a lot.  I’ve been taking supplements but I may need to up my dosage.  I’ll have to check into getting a test it sounds like  Great information.  Thank you!

      Thanks for your comment Lynn, may be a good idea to have your blood tested to see where your vitamin levels are before increasing your dosage. The fatigue can be caused by many different issues annd the vitamin deficiency may not be the issue. Hope that you get to feeling more energized soon!

    The vitamin D thing is interesting. I live in Australia where for the most part, we get sunshine. But once when I had a blood test, it showed my vitamin D was low! And I have fair skin, so I don’t have any of the typical risks for low vitamin D based on where I live, or my skin colour, or my age. I often walk the dog, so it is not like I am not getting sun exposure. So, I definitely agree with you when you say it is worth getting a blood test to get it checked out and also to avoid taking vitamin D when you might not need to given that we have a plethora of vitamin supplements we could be taking these days. Thanks for the info!

      Thank you Liz for your comment and that is a good point you bring up about your blood test and how important it is to get it tested. It can reveal issues that you are not aware of, but may need to take care of before it causes a more severe problem.

  • John says:

    Thanks for this post on vitamin D deficiency Chad. I found this particularly helpful as I have had the vitamin D test which showed I was deficient. I have been taking supplements as you suggested to help boost my vitamin D and plan to get re-tested in the new year. I wasn’t aware of some of the symptoms of Vitamin D deficiency you mentioned such as impeding the body from healing itself, so that was very enlightening.

      Thank you John, its good to raise the awareness of the symptoms during  this time of year.

    The lack of vitamin d in the winter must have something to do with the colds people get. I do get more pain in my muscles in the winter and now I know why. I have a lot of these signs of vitamin d efficiency and I will have to try out the natural supplements they have on the market. Thanks for the info.

      Thank you for your comment glad you got something out of the article.

    I read this and I remember again one of the main reasons why I live in Thailand. The cold and unhealthy climate I used to lived in in Switzerland.

    Although it also had some health benefits, I get the flu here once a year too. But the absence of sunlight and Vitamin D is no concern here for sure.

    Why I came to this article, I have to go back to Switzerland for some months very soon and want to be prepared. I’m not used to that kind of climate anymore and want to have some supplements when I am there.

    • Chad Trader says:

      Thank you for your comment and sounds like a good plan to prepare for the change in  climate. Sometimes it is easy to forget to take these things into consideration when traveling.

    I take vitamin D a lot.  I take quite a bit and ok’d by my physician.  

    I started noticing vitamins and the effect the lack of some would have on me.  I began feeling tired in winter, i had a bit of depression, and muscle fatigue.  I am generally a happy person with lovely kids a wife.  I go to the gym daily and never felt the way I did.

    I was suggested vitamin D by a friend and started taking it and have never looked back.  What a revelation this is.  All my symptoms disappeared and haven’t returned after 3 years.  I don’t think I will ever give it up.

    • Chad Trader says:

      Thanks for sharing that Stew, good to hear about somebody getting the help they need.

    Thank you for your excellent article concerning Vitamin D deficiency.

    Vitamin D deficiency has become very common especially in older people.  We tend to stay indoors more, and are always told to restrain from direct sun exposure due to concerning of various forms of skin cancer – especially melanoma.

    While this is good advice for reducing the risk of skin cancer, it also tends to reduce Vitamin D.  We all make Vitamin D naturally but require sunshine exposure for this to happen.

    It used to be Vitamin D deficiency was reduced through drinking milk which is nearly always supplemented with Vitamin D.  However, now most adults no longer drink milk in any quantity.

    Thanks for your interesting article which is now even more important to those of us in the Northern Hemisphere where the nights are very long and sun exposure is reduced even more.

      Thanks for your comment Dave, sometimes we stop things, like drinking milk, and don’t think about how it could be affecting other aspects of our health. Forgot about milk being a source of Vitamin D, thank for the reminder.
