Vitamin D is one of the very vital vitamins in the body. Its main job is to aid in maintaining normal levels of calcium and phosphorous in the blood. It also helps in absorbing calcium from the intestines, thereby helping in the mineralization of bones. People need vitamin D for strong healthy bones Vitamin D deficiency is responsible for rickets in children and osteomalacia in adults, which are both characterized by the weakening of bones which may cause serious problems if it goes untreated. Other benefits of vitamin D include promotion of proper function of the nerve and muscle, boosting immune function and alleviating inflammation of the body, among other. This means that having adequate amounts of vitamin D will protect the body against diseases like cancer, hypertension as well as some autoimmune diseases. Knowing about the importance of vitamin D, one may be concerned and ask what is the effect of warm clothing on vitamin D, especially when the weather is cool.

People get their intake of vitamin D from their daily diet, vitamin D supplements, and most importantly, from exposure to the sun. The foods that have naturally occuring vitamin D are not many. They include cod liver oil, fish, eggs and some mushrooms. This has brought about the need to fortify some foods with the supplementary form of vitamin D to prevent deficiency. People who have regular exposure to sunlight rarely have vitamin D deficiency because the ultraviolet rays causes the skin to synthesize vitamin D in the skin. Experts recommend about 20 minutes every day out in the sun to get enough daily amount of vitamin D. If a person is wearing warm clothing and is out in the sun, the clothing blocks the rays of the sun from reaching the skin, which limits or prevents that person from enjoying the benefits of exposure to the sun. The same thing may apply to people who live in hot areas but cover their bodies from head to toe, only leaving the face or eyes exposed. These people may suffer from vitamin D deficiency if their diets do not include foods that contain the vitamin D.

Other people who may be at risk of getting vitamin D deficiency include their dark skinned people whose skin melanin becomes a natural sunblock, which means that if their diet does not contain vitamin D, they need to stay longer in the sun that a light skinned person to achieve the same amount of vitamin D. Supplementation is recommended for such people as well as older people, pregnant and nursing women as well as those with fat absorption problems. With these facts at hand, one may no longer ask what is the effect of warm clothing on vitamin D.
