Like sunlight itself, a solarium makes you feel happier and more energetic. It also encourages your body to produce more vitamin D, which is essential for your health. Not only is vitamin D necessary for the health of your bones, but it also plays an active role in more than 36 other bodily functions! During the winter months, many people suffer from an inadequate supply of vitamin D. Sometimes we quite simply don’t have the time to go outdoors and soak up the sun. So well filtered, artificial sunlight is a safe and convenient alternative.
