Fun Fact Friday!

From November through February, people that live north of the 37th latitude experience a “Vitamin D Winter,” meaning the sun’s rays are unable to stimulate Vitamin D production in the skin. This means that even if you get a sunburn on the ski slopes, you do not make any vitamin D and may become deficient. Researchers believe that the lack of Vitamin D production during this time of year contributes greatly to the timing of cold and flu season. In the United States, the 37th latitude is a line that runs from around San Fransisco, along the borders of Arizona/Utah, New Mexico/Colorado, Oklahoma/Kansas, Arkansas/Missouri, Tennessee/Kentucky, and North Carolina/Virginia. People living north of this line should be supplementing Vitamin D during the winter months
