Vitamin D is one of the most important nutrients our bodies need in order to survive and to reduce our risk of all types of diseases. Yet, vitamin D deficiency is widespread in the United States and other industrialized countries where people spend most of their days indoors.
If you work indoors and do not get some exposure to sunlight on a regular basis you are compromising your health by being deficient in vitamin D. It is extremely difficult to get all of the vitamin D your body needs for good health without some exposure to sunlight.
VITAMIN D SOURCES
Your body has only two vitamin D sources: sunlight and food. Sunlight on our skin is a lot more important for our vitamin D levels than food. However, the farther away from the equator we live, the less sunlight is available, especially during the colder months. In spring and autumn you need to get your sun around midday to make enough vitamin D. In winter, it is not possible to get enough from the sun so you should take a good quality vitamin D3 supplement.
This makes food, a secondary source of vitamin D, very important. What are the best food sources for Vitamin D? Fortified foods, such as cereals and orange juice, provide some vitamin D, but not nearly enough to prevent vitamin D deficiency. The best food sources of vitamin D are salmon, mackerel, sardines, tuna, and cod liver oil. You can acquire enough natural vitamin D from your diet, but you have to eat a lot of fish.
GUIDELINES FOR USING SUNLIGHT AS A SOURCE OF VITAMIN D
Most of us can use the sun as our source for vitamin D at least part of the year.
*Vitamin D production occurs naturally before your skin burns. Use common sense when in the sun. If you are fair-skinned you need only a short time but if you are dark-skinned, you will need longer. Never allow yourself to burn.
*Try to expose as much of your skin as possible. The more skin exposed, the less exposure time you need. Turn over to maximize the area of your skin that is exposed.
*Do not wear sunscreen (except on your face). Wear sunglasses to protect your eyes. Sunscreen absorbs the rays that your body needs. What is left is not enough for your body.
*When you are through, go inside and cover up. Give your skin a chance to absorb the vitamin D. Your goal for sun exposure should be 3 or 4 times a week.
*If you have areas of skin on your body that are sun-damaged, do not expose them to the sun.
RISKS OF VITAMIN D DEFICIENCY
Vitamin D deficiency is linked to an increased risk of:
*Auto-immune illnesses
*Infectious diseases (colds, flu, tuberculosis)
*Leukemia
*Many types of cancer
*Diabetes type 1 and 2
