We all love the sunshine, but too much of it can lead to premature ageing, sunburn and even skin cancer. That’s why it’s so important to protect our skin from the sun’s harmful ultraviolet (UV) rays with a good sunscreen and protective clothing.

But did you know that there’s a vitamin that can also help to boost your sun protection? That’s right – vitamin D could be just what you need to help keep your skin healthy in the sun. Let’s take a closer look.

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that is essential for strong bones, muscles and overall health. Our bodies are able to produce vitamin D when our skin is exposed to sunlight, but we can also get it from certain foods and supplements.

Vitamin D is actually a hormone and is involved in many important functions in the body, including regulating the immune system and reducing inflammation.

How Does Vitamin D Protect the Skin?

When our skin is exposed to UVB rays from the sun, a chemical reaction occurs that converts a substance in our skin, 7-dehydrocholesterol, into vitamin D3.

This vitamin D3 is then transported to the liver and kidneys where it is converted into its active form, calcitriol. Calcitriol can then help to protect the skin in a number of ways.

Vitamin D Boosts Your Skin’s Immune System

Calcitriol has been shown to boost the skin’s immune system by increasing the production of natural antimicrobial peptides, which help to defend against harmful bacteria, viruses and fungi.

This can help to prevent infections, which can be especially important for people with compromised immune systems, such as those undergoing chemotherapy or organ transplants.

Vitamin D Reduces Inflammation in the Skin

Inflammation is a natural response of the body to injury or infection, but chronic inflammation can be harmful to the skin and lead to premature ageing.

Calcitriol has been shown to reduce inflammation in the skin by inhibiting the production of pro-inflammatory cytokines and increasing the production of anti-inflammatory cytokines.

Vitamin D May Help to Prevent Skin Cancer

There is some evidence to suggest that vitamin D may help to prevent skin cancer.

A study published in the Journal of the National Cancer Institute found that people with higher levels of vitamin D had a decreased risk of developing melanoma, the deadliest form of skin cancer. Vitamin D may also be able to inhibit the growth of cancer cells in the skin.

How Much Vitamin D Do You Need?

The amount of vitamin D that you need depends on a number of factors, including your age, skin colour and how much sun exposure you get.

The US National Institutes of Health recommends a daily intake of 600-800IU (International Units) of vitamin D for most adults. However, some experts believe that these recommendations may be too low and that many people may need more vitamin D than this.

How Can You Get More Vitamin D?

The sun is the best source of vitamin D, but it’s important to balance the benefits of vitamin D with the risks of sun damage.

The amount of vitamin D that you can produce from sun exposure depends on a number of factors, including the time of day, season, location and your skin colour. In general, the further away from the equator you are, the less vitamin D you’ll be able to produce from sun exposure.

If you’re not getting enough vitamin D from the sun, you can also get it from your diet or supplements.

Good food sources of vitamin D include oily fish (such as salmon, mackerel and sardines), egg yolks and fortified foods (such as breakfast cereals and some dairy products). Supplements can also be a good way to ensure that you’re getting enough vitamin D, especially during the winter months or if you have limited sun exposure.

Conclusion

Vitamin D is an important nutrient that can help to protect your skin from the harmful effects of the sun.

By boosting your skin’s immune system, reducing inflammation and possibly even helping to prevent skin cancer, vitamin D could be just what you need to stay healthy in the sun. If you’re not getting enough vitamin D from the sun or your diet, talk to your doctor about whether supplements are right for you.
