Eczema can refer to a number of skin conditions but the most common atopic dermatitis, a condition that causes the skin to become itchy, dry and cracked. As the NHS explains, some people only have small patches of dry skin, but others may experience widespread inflamed skin all over the body. These symptoms can prove highly disruptive, both to your physical and mental wellbeing.
What’s more, research has indicated a correlation between vitamin D and skin moisture.
A study in 83 women found that those who had low vitamin D levels had lower average skin moisture than participants who had normal vitamin D levels, and that as blood levels of vitamin D increased, skin moisture content increased as well.
This is significant because people with atopic eczema often have very dry skin because their skin is unable to retain much moisture.
This dryness may make the skin more likely to react to certain triggers, causing it to become itchy and sore.
Another small 12-week study in 50 women observed that daily treatment with a nutritional supplement containing 600 IU of vitamin D led to significant improvements in skin hydration.
However, the supplement contained a combination of nutrients, so it’s unclear whether treatment with vitamin D alone would have resulted in the same positive outcome.
General tips to alleviate symptoms
It is important to resist scratching the affected area because this can worsen symptoms.
Scratching usually damages the skin, which can itself cause more eczema to occur, the NHS warns.
You should also establish your eczema triggers and take steps to avoid them.
“A GP will work with you to establish what might trigger the eczema flare-ups, although it may get better or worse for no obvious reason,” says the NHS.
As the health body points out, once you know your triggers, you can try to avoid them.
For example:
- If certain fabrics irritate your skin, avoid wearing these and stick to soft, fine-weave clothing or natural materials such as cotton
- If heat aggravates your eczema, keep the rooms in your home cool, especially the bedroom
- Avoid using soaps or detergents that may affect your skin – use soap substitutes instead.
