said that the sun is dangerous, sometimes causing skin cancer.
So, should fair-skinned people use sun block when sunning?
What amount of time should one sun to receive the proper "input " amount of vitamin D, if one recieves it no other way?
Why do laborers, laboring in the sun every day, (with shirts off) not get melanoma?

Does anyone have experience with this, whether it really produces the proper Kelvin readind to be helpful?

According to Reuters Health article
" a Little Bit of Sun May be a Good Thing: Experts" by Anne Harding, researchers spoke at the annual meeting of the American Association of the Advancement of Science, on the positive effects of solar radiation on the human body. Dr. Michael Holick of Boston University School of Medicine noted that vitamin D helps keep bones strong, and helps control cell growth.
But don't overdo it. Too much sun without protection can damage your skin. No need to spend hours and hours at the beach. But do make sure to spend some time, every season, in the sun to keep your body strong and healthy. And getting some sun is another reason to lace up those running shoes, get out the door, and go for a run.
Melanoma skin cancer is caused by too much sun exposure but keep in mind everyone's skin is different and offers different levels of protection due to their amout of pigment in their skin. Black people can stay in the sun much longer than white people due their high amount of pigment in their skin. Black people do still burn and do still get skin cancer however, just that their at a lower risk of it. Bottom line here is to get some sun regularly and then cover up! I am not positive that sunblock stops the production of Vitamin D so you might want to ask that question. Good luck!

If a person has a balanced, nutritional diet, he will usually get the amount of Vitamin-D necessary. Yes, you can get Vitamin-D from sunlight, but it takes very little to get it. The ultraviolet rays of the sun (especially in strong sunlight) is the culprit of skin melanoma when sunscreen isn't being used properly and of the proper SPF. Laborers are just as likely to get skin cancer; however, clinicals have shown that people who are of lighter complexions have the greatest risk because they have less melanin (pigmentation/color) in their skin. Darker- skinned persons have more, so they do have SOME protection. People of any skin color can get skin cancer; it's just that lighter-skinned people are at greater risk.

15 mins of sun exposure is all you need for Vitamin D absorption. Not an hour.
I am fair skinned and if I'm going to be in the sun for more than 30 mins, yes I wear sunscreen.
How much at risk you are to skin cancer is based on how many moles you have, your skin type and how many bad sunburns you have had in your lifetime.

Just wanted you to know my professor in college who is a medical Dr. said you only need to step out in the sun for a second to get all the vitamin D you need for the synthesis of the Calcium to work.

Actually 5-15 min is a sufficient amount of time per day to get our "d" which is actually a hormone not a vitamin-but you probably know that. Have a good one!
