Over the past several decades, researchers have discovered that vitamin D is essential for many important functions in our bodies, such as maintaining bone health and a strong immune system, but the benefits of “the sunshine vitamin,” as vitamin D is often called, go beyond staying in good physical health. There is a growing body of research that vitamin D plays a key role in regulating mental health as well.

While the relationship between mental health and vitamin D isn’t yet fully understood, we are beginning to piece together the puzzle. One study published earlier this year concluded that vitamin D is essential to the synthesis of serotonin, an important neurotransmitter responsible for generating a sense of calm and well-being. In light of these findings, Tranquility Labs recently added vitamin D to our anxiety-fighting Tranquilene formula so that the supplement now offers even better support for serotonin production.

One thing that we know for certain is that it’s incredibly common for those with anxiety disorders and depression to also have a vitamin D deficiency. And now, new research suggests that low levels of vitamin D may play a significant role in seasonal depression and anxiety (commonly known as SAD).

Sunlight, Vitamin D, and SAD

Full-blown Seasonal Affective Disorder affects up to 10% of the U.S. population, with an estimated additional 10-20% experiencing milder form of the wintertime blues. It’s currently thought that the primary reason for the onset of SAD is less light exposure — although those of us in cold climates have a good argument that the temperatures also have something to do with it!

Vitamin D is known as the sunshine vitamin because our primary source of it is exposure to sunlight. This is why the risk of deficiency is especially high in the wintertime, with shorter daylight hours and increased indoor time. Individuals in Northern climates are even more at risk, but you can have low levels of vitamin D no matter where you live.

Because both SAD and vitamin D deficiency are associated with lack of sunlight, the new study’s conclusion that low vitamin D plays a role in SAD just seems to make sense.

“Rather than being one of many factors, vitamin D could have a regulative role in the development of SAD,” said Alan Stewart, one of the study’s authors. “For example, studies show there is a lag of about eight weeks between the peak in intensity of ultraviolet radiation and the onset of SAD. This correlates with the time it takes for UV radiation to be processed by the body into vitamin D.”

The study was published in the November 2014 issue of the journal Medical Hypotheses.

One thought on “Are You SAD? Low Vitamin D Levels Linked to Seasonal Depression

  1. Positive thoughts are more pouwfrel but you need to understand somethings first.1. Negative thoughts don’t just come. We are lead to believe that all thoughts are of our own thinking and that is not the truth. For you to have negative thoughts there have to be people related to you, whether by blood, friendships, work, neighbors, social etc., who are toxic. Relationship means ESP is strong and thus these thoughts can be repeatedly presented to you.1a. ESP is greatly enhanced if they can present you with some sort of danger to make you fearful because with fear all types of perception are enhanced but at the same time thinking and discrimination is suspended until we determine the nature of the danger. Don’t worry about it the danger is always Mickey Mouse, even if they have weapons. It is only aimed to make you fearful and all you will be aware of is feeling a bit hot and not that you are fearful.2. These people are usually motivated out of jealousy or to try and obtain power and influence over you to manipulate and control you. There is also a third very common motive and that is that toxic people get pleasure out of hurting other people around them.3. You can assess who these people might be by looking at the material that comes to mind. Who knows of your financial situation, your past relationships and how they ended, who knows about the stuff that is coming to mind?4. Toxic people befriend others for the purpose of hurting them and for that reason they do not appear obvious at all. On the contrary if you were to make a lisst of all those that you suspect then chances are these people would not even be on your list.5. The most important thing to know is that all that is presented to you is suggestion only. YOU are the only one that can make choices and thus found your reality. You provide the basis of your life. All else is just suggestion and suggestion is null and void unless you accept it.6. You don’t need to know who these people are to be able to stop them from hurting you. Just draw a picture, using your imagination, of say their head sawn off and in a bucket of their own blood or something nasty like that. You can then tear up the picture or erase it from your computer and throw it away. It is only important to get a visual picture so that your counter mental image is strong. Thus when these thoughts come up, which they won’t once you’ve made the picture, then you just hold the picture in mind. It doesn’t matter if you can’t visualize it consciously it still works.7. Now knowing that you are the only one with the power to make choices and provide the universe with the directives that dictate your life you can go forward and make positive ideas for yourself.8. Always state your reality as if it has already happened. So avoid words like will be or may be etc. State I have now . whatever it is that you want. When we ask of the universe and ask appropriately and for ourselves and our protection we ALWAYS get what we ask for. It is the nature of the reality in which we live.
