Vitamin D, the sunshine vitamin, and the winter immune system

Updated: Aug 4, 2022

Vitamin D and the Winter Immune System

For the last few years during the Autumn and Winter months, I have taken a Vitamin D spray. The reason I do this is to try and strengthen my immune system as well as feel healthy during those days when the light levels are low.

Why is Vitamin D important?

Not having enough Vitamin D can cause a large list of symptoms, as Vitamin D has numerous functions in the body. Vitamin D:

  • Helps regulate the amount of Calcium and Phosphate within the body

  • Keeps bones, teeth, and muscles healthy

  • Supports immune, brain, and nervous system health

  • Helps to regulate insulin levels

How does sunlight affect the Vitamin D levels in your body?

When your body gets Vitamin D from the sun, it turns Vitamin D into a hormone, called Calcitriol. Calcitriol is what your GP would measure to assess your Vitamin D levels. Calcitriol is needed to absorb calcium from the gut into the bloodstream and is important to your overall health and well-being.

During the Autumn and Winter months, the sun’s rays may not be strong enough (depending on where you live) to produce Vitamin D.

How can you get enough Vitamin D in Winter?

During Autumn and Winter, I try to go out for walks and get as much fresh air (and hopefully sunshine!) as I can. However, for me, I feel that I do not get enough Vitamin D just by doing this.

So I use a Vitamin D spray. I also try and eat food that is high in Vitamin D. Foods include:

  • Fatty fish, such as salmon, and seafood (or you can take Cod Liver Oil, which is high in Vitamin D)

  • Mushrooms

  • Egg yolks

How does Vitamin D affect the immune system?

The role that vitamin D has on the immune system is complex because the immune system has to be perfectly balanced. If there is too much stimulation, an autoimmune disease can begin. If there is not enough immune system activity, infections can occur. More information on the effects of Vitamin D on the immune system is on the National Institute of Health website.

The Harvard School for Public Health published an article showing the importance of Vitamin D and the immune system. A study was done on Japanese schoolchildren taking daily Vitamin D supplements. Findings - those children who took the Vitamin D pill were much less likely to get flu than those who had placebo pills.
