How is vitamin D linked to skin cancer?

Vitamin D and Skin cancer

As we know that vitamin D comes from Sun in the form of ultraviolet (UV) radiation. A balance of sun exposure and sun protection can protect against vitamin D deficiency without putting you at risk of skin cancer.

The levels of UV radiation exposure can differ depending on the place you stay, time of year, time of day and the environment. If the UV radiation levels reach more than 3, people use sun protection. If the levels are below 3 then you do not need any sun protection, unless and until they are in high-altitude regions. Solariums have been linked to causing skin cancer and are not recommended as a way to treat vitamin D deficiency.

Recommended sunlight exposure

By exposing your face, hands, arms feet is good and it can reduce the risk of vitamin D     deficiency. You should protect your skin from the sun with sunscreen, clothing, a shade between 10 am and 3 pm. Reapply sunscreen every two hours.

Sun protection is not necessary during the winter months. People with very dark skin may need three to four times more exposure time than people with fair skin to achieve sufficient levels of vitamin D. This is because the pigments in dark skin reduce the effects of UV radiation in the production of vitamin D.

Benefits of Vitamin D

Vitamin D is one of the most important vitamins in terms of long term health throughout the body. Vitamin D acts more like a hormone than a vitamin, directly affecting genes responsible for controlling nearly every aspect of cell development

  1. Depression
    Vitamin D is an important nutrient for mental well being. Light therapy, which helps raise levels of vitamin D in the body is used to treat women with seasonal affective disorders, schizophrenia, depression and other mental disorders.
  2. Strong Bones
    Vitamin D helps the body absorb calcium, an important nutrient for building bone and slowing bone loss. It also helps to treat the symptoms of osteoporosis.
  3. Blood pressure
    In one of the study, people with hypertension exposed to UV B light not only increased their vitamin D levels about 180 percent but reduced their blood pressure to normal levels.
  4. Diabetes
    Research is under way to determine if high vitamin D levels may help prevent or delay the onset of type 2 diabetes is in adults who have pre diabetes and are at high risk for type 2 diabetes.
  5. Cancer Risk
    maintain high levels of vitamin D could reduce the risk of breast cancer as much as 50 percent, colorectal cancer up to 253 percent, and heart disease, stroke and peripheral artery disease more than 100 percent.
  6. Immune system
    Low vitamin D levels put women at risk of infectious diseases like colds and flu. Vitamin D helps immune system cells destroy the bacterium that causes tuberculosis, increases production of insulin and enable heart cells to contract.

The vitamin D for children of age 1 to 8 years is 2,500 to 3,000 IUs per day; for adults (including women who are pregnant or lactating), it’s 4,000 IUs per day. By taking vitamin D more than the recommended it may damage your kidneys or cause toxicity. It can also cause symptoms such as loss of appetite, nausea, vomiting, constipation, weight loss weakness, weight loss, confusion or problems with heart rhythm.
