Research summary
This study will investigate if low intensity ultraviolet (UV) personalized office desk lighting system during winter can be used to maintain
adequate vitamin D in healthy volunteers working in an office. It will evaluate whether the treatment is safe and
acceptable, and will confirm the minimum required UV dose.
Adequate vitamin D is essential for bone health. Sunlight is the most important source, and during winter vitamin D deficiency is common. Therefore strategies to maintain vitamin D are required and we wish to
know if enough vitamin D can be made in the skin with natural sunlight during summer and “top up” UV light during winter. We have developed a new personalized office desk lighting system with a small doses of UV which could effectively treat large numbers of
people without need for pills. We will measure vitamin D using blood tests & UV exposure using dosimetry badges in a crossover study of 20 healthy volunteers from an office with little natural sunlight will have their face and forearms exposed to low intensity UV eight hours each working day, for eight hours a day and an eight week control period during November – March (UV dose within EU regulations). The study will also help us understand attitudes to the UV treatment and if successful lead to a larger study.REC name
