VITAMIN D AND YOUR SKIN

Vitamin D and Your Skin

We all know that Vitamin D is essential to lovely health, but how does reconcile the necessity for Vitamin D, which humans can synthesize through sun exposure, with the necessity to protect your skin from skin cancer &, if they can be vain for a moment, unnecessary aging? I've written about this subject historically (see my earlier post), but armed with some new information on the subject I thought it was time to revisit this controversy.
Why Our Bodies Need Vitamin D and How to Get Enough


According to Dr. Jessica Wu, in her book Feed Your Face (pages 149-150), Vitamin D plays a vital role in our health for lots of reasons:

Our bodies need Vitamin D in order to maintain normal calcium metabolism and to support our bone health. Further, Vitamin D helps form strong, healthy nails, plays a role in cellular metabolism and the growth of new skin cells, and helps cease the effects of skin diseases like psoriasis.

There is a lot of debate in medical community about what the optimal levels of Vitamin D are. Different doctors recommend a sizable selection of doses for positive age groups so it hard to know what the correct dosage is. Positive groups are a risk for Vitamin D deficiencies: the fat, people with darker skin tones, the elderly, and skin cancer patients/survivors.

Vitamin D is essential for lovely health. It helps the body absorb calcium for strong bones and muscles, and recent research suggests that vitamin D also plays a role in stopping colon, prostate, and breast cancer as well as diabetes (types one and two), hypertension, and multiple sclerosis. Since a variety of cells (including the skin cells) contain vitamin D receptors, it's feasible that there's additional makes use of and benefits of vitamin D that they don't yet know about. And here's another thing: Lots of of my patients tell me they feel healthier when they've had a small sun  and so do I. Perhaps that is our body way of telling us that it needs vitamin D, as you might crave red meat in the coursework of your period since your body loses lots of iron when it's that time of the month.

You can receive the necessary amount of Vitamin D through diets and supplements like a multivitamin or a calcium supplement with Vitamin D in it. In terms of diet, foods that are rich in Vitamin D include some fish (like salmon, mackerel, and tuna), some varieties of mushrooms, fortified breakfast cereals, and dairy products that are also fortified with Vitamin D. Vitamin D is also present in small amounts in egg yolks, beef liver, and cheese.

Despite the fact that your diet alone or combined with supplements can give you Vitamin D lots of people persist in claiming that the only true way to get Vitamin D is to get it through sun exposure. Some people even say that they won't wear sunscreen for this reason. Personally, I disagree with this idea since going without sunscreen can expose you to a whole host of other issues like skin cancer.

But in the event you insist on getting your needed Vitamin D from the sun  how much sun exposure is necessary to do that? Not much.

How much vitamin D your body makes depends largely on where you live. For example, in the event you live above 40 degrees north latitude (that is like drawing a line from the northern border of New york across to Boston), then the sunlight isn't strong to make vitamin D in the winter, from November through February. On the other hand, in the event you live below 34 degrees north latitude (a line from Los Angeles to Columbia, South Carolina), then spending a couple of minutes a day outside will give you all the vitamin D you need, irrespective of the season.

  Another indicator of vitamin D production is the UV Index, which measures the strength of ultraviolet radiation on any given day. (You can look up the UV Index in any basic weather document.) recent study showed that when the UV Index is three, a fair-skinned individual will produce an adequate amount of vitamin D by exposing hands & face (without sunscreen) for ten minutes a day (it would take an hour to burn). In the summertime, when the UV Index might be 7 to 8, you might need only to minutes outside.

  A tiny sunlight can be lovely for you, but that is not an excuse to receive a rotisserie tan or to
