Do burqas stop women absorbing vitamin D? Expert controversially argues restrictive clothing blocks UV rays, but … – Daily Mail

Burqas do prevent women from absorbing vitamin D, however, this can be overcome with supplements and diet, a leading expert has argued.

The debate was ignited after UKIP leader Paul Nuttall said last month that a burka ban would help women boost their vitamin D levels from sunlight. 

Speaking to ITV’s Peston on Sunday, Mr Nuttall said: ‘There’s a myriad of medical research which shows if you don’t show your face or the rest of your body to the sun there will be vitamin D deficiencies.’ 

Vitamin D is required to keep bones, teeth and muscles healthy.

A lack of the vitamin can cause bone deformities, such as rickets, in children and bone pain in adults.

Here, in piece for The Conversation, Peter McCaffery, professor of biochemistry at the University of Aberdeen discusses what burqa and niqab-wearers can do to minimise their vitamin D deficiency risk.

Vitamin D tablets could help people cope with chronic backache and arthritis, it emerged last month.

The ‘sunshine supplement’ may help many pain-related conditions, from menstrual cramps to fibromyalgia, biologists concluded.

This is because Vitamin D, created by sunlight and found in oily fish, is believed to tackle inflammation.

Inflammation, the body’s immune response to illness, releases proteins that make people more sensitive to pain and cause it to last longer. 

The vitamin is already recommended for pregnant women and has been claimed to prevent dementia and multiple sclerosis, with some experts calling for it to be routinely added to food.

Lead author of the review, Dr Monica Levy Andersen, from the Federal University of Sao Paolo, said: ‘We can hypothesise that suitable vitamin D supplementation combined with sleep hygiene may optimise the therapeutic management of pain-related diseases, such as fibromyalgia.’ 

UKIP would like to ban the burqa and niqab being worn in public because it says they ‘are barriers to integration’. 

However, UKIP is also concerned about the health of women who wear these garments as – according to its manifesto – they prevent the ‘intake of essential vitamin D from sunlight’. 

As part of The Conversation’s Fact Check series, we asked two academics to check the science behind the claim.

The niqab and burqa, worn for cultural or religious reasons, cover the wearer’s body and face. 

They are made of opaque material that greatly reduces the amount of sunlight reaching the skin and hence the amount of vitamin D that the body can generate. 

However, this is not a problem as vitamin D needs can be satisfied by diet and supplementation alone.

There are a number of peculiar aspects of vitamin D that are necessary to understand so that deficiency is avoided.

Vitamin D, the ‘sunshine vitamin’, is unusual among vitamins. All other vitamins can only be obtained from diet, but vitamin D can also be made in the body. 

Synthesis by the body is dependent on a step requiring sunlight, specifically ultraviolet (UV) light reaching the skin. Without sunlight on the skin, little vitamin D will be made by the body.

For many reasons, people may not get enough sunlight. This can be because of the clothing they wear, because they have darker skin, because their jobs keep them inside, because they live at latitudes where the sun remains low in the sky, or because they purposefully keep out of the sun because of the known dangers of excessive sun exposure, namely skin cancer. 

Obesity also decreases the ability of the body to use vitamin D. Clearly, there are many reasons why vitamin D deficiency may occur.

But restricting sunlight does not cause a problem if a person gets enough vitamin D from their diet or supplementation (vitamin D pills). There are high levels of vitamin D in foods such as oily fish, and smaller amounts in liver and egg. 

In some countries, foods, such as breakfast cereals and milk, are fortified with vitamin D. If a person doesn’t get much sunlight, they will need to consume enough foods high in vitamin D or take vitamin D supplements.

Women can top up their vitamin D levels with supplements, argued Professor Peter McCaffery

Taking vitamin D supplements in pregnancy strengthens babies’ immune systems, which may lower their risk of developing asthma, research revealed last month.

The unborn babies of expectant mothers who take more than the recommended daily vitamin D dose for pregnant women respond better when exposed to simulated pathogens, a study found.

Previous studies have demonstrated a link between a strong immune system in early life and a reduced risk of asthma.

Researchers believe this may also extend to greater respiratory health overall.

Lead researcher Professor Catherine Hawrylowicz, from King’s College London, said: ‘For the first time, we have shown that higher vitamin D levels in pregnancy can effectively alter the immune response of the newborn baby, which could help to protect the child from developing asthma.’ 

Without vitamin D, serious health problems are inevitable. Vitamin D is essential to control the correct levels of calcium in the body, necessary for good bone health. 

Deficiency of this vitamin is the cause of bone weakening and deformities, such as rickets in children and osteomalacia in adults.

Rickets are a problem in many parts of the world, including places with an abundance of sun but where people are not exposed to enough sunlight. 

Vitamin D deficiency occurs in countries where wearing of the niqab and burqa is prevalent, such as Saudi Arabia, but also in countries like Australia where sun exposure is reduced for other reasons, such as effective public health campaigns about skin cancer.


The niqab and burqa do prevent the intake of vitamin D from sunlight. 

But problems only occur when the person is unaware of the potential damage due to lack of sunlight and does not redress this by increasing their vitamin D intake through diet or supplements.

I agree with the author’s analysis. Setting the claim in the context of scientific evidence here is important for a meaningful examination of the manifesto claim.

Covering the skin is one of a number of risk factors for vitamin D deficiency, and, indeed, in the UK in winter there is inadequate sunlight for vitamin D production. In summer the level of exposure varies according to a number of factors from skin type, latitude, altitude to time of day. 

Most of the UK population is at risk of low vitamin D for some of the year. If we extrapolate the findings of a recent European study, over 30m people in the UK are estimated to have vitamin D deficiency or insufficiency. And our recent study of 116 UK-based healthy volunteers found that only 14% had normal serum vitamin D concentrations. 

So, the premise of the UKIP statement that wearing a niqab or burqa is an important risk factor for vitamin D deficiency is questionable in settings such as the UK, as, for most of the year, no one else is making any vitamin D via their skin.

Recent guidance from NICE on the prevention of vitamin D deficiency recommends that those ‘at risk’ should take daily vitamin D supplements. Evidence-based public health measures on vitamin D are welcome, and universal supplementation strategies in at risk groups can be effective. Nobody needs to suffer from vitamin D deficiency, regardless of what they wear.
