How Low Vitamin D Affects You

It seems the sun is great for enhancing not just your tan but your mood too. And that’s not a coincidence.

The reason why our body craves vitamin D is that it is necessary for our survival. We all need some sunshine in our lives. For some, getting that sunshine is easier than others.

If you’re living in sunny SoCal, finding enough vitamin D to keep your body may not be a difficult task. However, if your home is somewhere like Alaska where the sun isn’t quite as abundant, then you may find yourself struggling to get what your body needs. And this can definitely be a problem.

When you don’t have enough vitamin D in your life, your body is bound to suffer. Just how exactly?

Here, the ways that low vitamin D can affect your body, and the reasons why you ought to make it a priority to get enough of the essential nutrient in your life.


A lack of vitamin D in your system can lead to depression. This may not come as a surprise to you, as vitamin D is typically known as the happy vitamin because of the main source from which it comes — the sun. However, the sun is not the only way you can get vitamin D.

If you happen to live in a place that does not have the option of the sun as much as others, it’s important that you take a supplement to make up for it. Research has shown that women who suffered from depression showed an increase in their levels of happiness when their intake of vitamin D was increased.


Low vitamin D will also undoubtedly affect your sleeping habits. If you are not getting enough vitamin D, then you are not getting enough sleep. A study published in the Journal of Sleep Studies showed that people who had a sufficient amount of vitamin D in their bodies proved to have better-sleeping patterns than those that did not.

Susceptibility to Illness

Another thing that a lack of vitamin D can do to your body is to weaken your immune system. Vitamin D helps your cells fight infection, and when you don’t have enough of it, then your body will become weaker and you’ll be more likely to pick up sicknesses going around. By simply upping your daily vitamin D intake via supplements, your risk of developing illnesses (respiratory tract infections specifically) will greatly decrease.

Bone Pain

Did you know that vitamin D plays a major role in keeping your bones healthy? It does that in a number of ways, one of which is by helping your body to absorb calcium. Studies have been down that show people suffering from low levels of vitamin D were more likely to have moderate to severe back pain.

In addition, too little vitamin D in your system means for many people bone pain, particularly in the legs and joints — in fact, one specific study revealed vitamin D deficiency made people twice as likely to experience bone pain.

Loss of Bone

As mentioned above, vitamin D aids with your body’s absorption of calcium. It also is necessary to keep your bone metabolism healthy. Those who suffer from low bone mineral density are dealing not only with a lack of calcium, but other vital nutrients as well — including vitamin D.

Muscle Pain

Though there are a number of things that can cause muscle pain, one of them is thought to be vitamin D deficiency. Results from studies bring to light the fact that the majority of people who suffer from chronic muscle pain also happened to be vitamin D deficient. That seems a bit too much of a link to be mere coincidence, doesn’t it?

Hair Loss

Though this one is a bit more difficult to determine whether the culprit is a lack of vitamin D, studies have shown a link between people who suffer from hair loss and their low levels of vitamin D. There certainly is a connection between a lack of vitamin D and an increased risk of developing alopecia areata, an autoimmune disease that causes massive hair loss all over the body.

Brain Fog

Though scary, it seems natural that when your body lacks a certain vital nutrient, your brain will be affected as well. And this is certainly the case with vitamin D. When your levels of vitamin D are not high enough, according to a number of studies, brain fog sets in. It may not be extremely noticeable, but you will likely feel as if you’re still partially asleep or in some serious need of caffeine.

By upping your vitamin D intake, chances are good your brain fog will disappear and you will feel more clear-headed and able to focus.

Vein Issues

When your body does not have enough vitamin D, your blood vessels will likely suffer. Vitamin D helps to keep your arteries and blood vessels loose enough and relaxed enough to support proper blood flow. Thus, when vitamin D levels are low, your veins will struggle to do their job properly, and vein issues will arise. As you can see, when your body is low on vitamin D, far more than your tan suffers.

Vitamin D is, without a doubt, a vital nutrient that your body needs in order to properly function. The good thing is that getting enough vitamin D in your body is not difficult to achieve.

If you aren’t able to get enough natural vitamin D from the sunlight, then a supplement is all you need to keep your levels at an optimum spot.
