Children with a vitamin D deficiency are more likely to develop asthma and other allergies.

The Telethon Kids Institute studied children under 10 who were genetically at risk of the condition, and found those who spent less time in the sun were more susceptible to asthma, allergies and eczema, reports ABC news.

The study’s lead researcher, Elysia Hollams, said this was because vitamin D was important for immune function.

“Vitamin D can help to promote tolerance to allergens,” she said.

“So that means our immune system can ignore things that are harmless to it.

“When we get allergies is when our immune system has a response to something that it should just ignore.”

The first two years of childhood have been flagged as a critical period for allergies and chest infections to begin growing into something bigger, but enough vitamin D can help prevent the development of asthma.

The study considered 50 nanomoles per litre as the cut-off for low vitamin D levels, but Doctor Hollams said they were yet to come to a conclusion about how much vitamin D children should be getting.

“That’s the million dollar question, we really don’t even know what range of vitamin D is optimal for normal immune development,” she said.

Although vitamin D supplements are available, Doctor Hollams said parents needed to make sure their kids spent sufficient time in the sun.

“As vitamin D is a marker of sun exposure, we don’t know whether just giving supplements can give the full benefit of healthy sun exposure,” she said.

In a statement, the study’s co-author Prue Hart reminded parents too much sun exposure could be harmful.

“In summer, it’s still important to wear sun protection during the hottest parts of the day and when the UV index is three or above,” she said.

  • Who would have thought vitamin D deficiency would happen in a place like Australia

  • WARNING RANT ABOUT TO HAPPEN – I am so jolly sick of pedestrian tests, etc being reported as facts. If this was so, my autistic son would be my fault, and my illnesses that I do not chose to share, be the fault of those that did not know better. HOW IRRESPONSIBLE!

  • I wonder if this has any impact of being vitamin D deficient in pregnancy?

    This year my 3yo son was diagnosed as asthmatic, however there is no genetic disposition and I was vitamin D deficient when I was pregnant with him.

  • Just another reason why kids should get outdoors and have a little play.

  • Always knew that the more time your children stayed outside, the better they were overall.

  • Very true what you say. If they would test the vitamin D of everyone, a huge percentage will be deficient. We use solar cream to protect our skin from cancer, but this way we do not get enough vitamin D. And that’s so important. Not only for our body, but our mind too. It’s clearly linked to depression for example.
    I read a very interesting book about it, years ago: “The Vitamin D Revolution” by Soram Khalsa. It really gives a great insight about the role that vitamin D plays in our body.

  • I doubt this information has much science in it because I have a Vit. D deficiency & was put on a supplement. I argued that I could spend more time in the sun rather than take more medication but the specialist’s reply was no amount of sunshine will be enough because we use sunscreen & wear clothes to protect us against skin cancer. The most common symptom from a Vit. D deficiency is bone pain which is how mine was picked up & apparently we are experiencing a world wide epidemic of ppl who need to take a supplement especially as we age because we are so scared of developing cancer from the sun.
    We do need a certain amount of sun each day I was told after having a cancerous growth removed from my ear as I had avoided going out in the sun because of it. The amount of sun without sunscreen needed to make up for a deficiency is going to put you at risk of skin cancer, your GP can do a simple blood test if you think you have a problem & the cheap brands are just as good as expensive ones so long as you use D3.

  • Asthma can be genetic. A baby can even show symptoms of it soon after birth.
    I know of one. Even if your baby is given sun exposure time, one cause of asthma can be allergens to pollen from grass, flowers etc. The more the baby / child is exposed to them the worse the asthma is. Some if their asthma becomes less frequent can be more severe and affect their heart. I personally know a teenager who is having that issue.

  • I found this really interesting. My son has hay fever and asthma, which is totally foreign to my husband and I, as we don’t. We’re just learning as we go along and trying our best to help our son deal with it. Now he’s 15, it’s a little easier for him to manage and understand, however it’s also now at its worst. I might try including Vitamin D in his daily routine.

  • An interesting article and study – more information and demographics would be handy.

  • Of course more factors beside vitamin D are playing a role in the development of asthma and other allergies, but vitamin D is certainly important for all of us.

  • Vitamin D is so important. And because of the large use of solar cream protection, more and more people have a vitamin D deficiency.
