Sun Exposure and Vitamin D

Vitamin-DThe right amount of sun exposure is essential to maintain optimal vitamin D levels in the human body. Several studies have shown that people who do not get enough sun exposure may need vitamin D supplementation, particularly in northern countries where sun exposure is minimal during the winter months.

With an extensive list of ongoing studies on this subject, a new study is set to take place in Australia, examining whether people are getting too little, too much or just enough sun exposure. Many people have low vitamin D levels in Australia but the country has also a high incidence of skin cancer. Thus it is a difficult task in making sure people get the right balance of sun exposure, enough to make vitamin D but not too much where you start to burn. Universities and research centers are teaming up with Cancer Australia and are gathering about 1,000 people for the Sun Exposure vitamin D Supplementation (SEDS) study.

The subjects will be given sun exposure advice, a vitamin D supplement or placebo, and some will receive a dosimeter wristband, which will measure precisely how much sun exposure they’re getting. Furthermore, the dosimeter will alert the participants when their skin has gotten adequate sun exposure. The goal is to establish an understanding of the amount of sun exposure, if the behavior needs to be modified, and ultimately answer the question of whether people should seek more sunlight, or look to supplements. The study has just finished gathering its participants and hopes to have all data collected to begin analyzing in December 2014. Taking vitamin D supplements during the winter is one of the best ways to ensure adequate levels of this important vitamin.
