One third of UK adults spend less than an hour per day outdoors, according to new research conducted ahead of National Vitamin D Awareness Week (19th – 25th October).
Our 'indoor' lifestyle and lack of British sunshine is placing millions of Brits at risk of vitamin D deficiency, warns ITV's Dr. Chris Steele.
A further 50% of the 650 people surveyed in the Pharma Nord consumer poll spend less than 2 hours per day outdoors, while just 5% spend more than four hours outside.
The majority of our vitamin D requirement – around 90 per cent – must be created in the skin in response to strong sunlight. Up to 50% of UK adults are thought to be deficient in this vital 'sunshine' vitamin, with the highest rates of deficiency in Northern England, Scotland and Northern Ireland due to limited sun exposure.
Vitamin D deficiency costs the UK taxpayer £29 billion annually – more than a quarter of the NHS budget. Despite the prevalence of deficiency, three quarters of UK adults admit that they have never had a vitamin D test, either through a GP or a self-test.
The importance of vitamin D
Low levels of vitamin D have been linked to seasonal affective disorder (SAD), a type of depression that comes and goes in a seasonal pattern, with symptoms often more apparent and severe during winter.
A lack of vitamin D is also associated with poor immune health, susceptibility to colds and flu and tiredness and fatigue.
The new survey from Pharma Nord, developers of Bio-Vitamin D3, has revealed that:
Commenting on the research, Dr Chris Steele, medical doctor and ITV This Morning's resident GP said: “There needs to be greater awareness of the risk of vitamin D deficiency in the UK. While all of us could be affected, the higher risk groups include those aged over 65, pregnant and breastfeeding women, ethnic minorities, children and people who spend large amounts of time indoors.
"I would urge all UK adults, and particularly people in these groups, to discuss with their GP a vitamin D test and the taking of a high quality vitamin D supplement. There is often confusion over the best form of vitamin D to take, so look for vitamin D3 as this form is identical to the kind produced naturally in the skin. Also oil-based capsules can be more easily absorbed by the body compared to dry, chalky tablets."
Dr David Mantle, medical adviser at Pharma Nord added: "Common symptoms of vitamin D deficiency include tiredness or fatigue, low mood, particularly during the winter months, and a greater susceptibility to colds and flu. Worryingly, there are a large number of people living with deficiency. As 90% of our vitamin D requirement must come from the sun, I would recommend a vitamin D supplement such as Pharma Nord's Bio-Vitamin D3 to ensure you have sufficient levels.”October 2015
