Both UVA and UVB can cause tanning and burning, although UVB does so far more rapidly. UVA, however, penetrates your skin more deeply than UVB, and may be a much more important factor in photoaging, wrinkles and skin cancers. A recent study found that indoor workers may have increased rates of melanoma because they’re exposed to sunlight through windows, and only UVA light, unlike UVB, can pass through window glass. Please see this link if you wish to educate yourself on this subject: http://articles.mercola.com/sites/articles/archive/2009/05/02/Can-Working-Indoors-Give-You-Skin-Cancer.aspx Our Sun not only gives us codings and attunments which prepare our DNA for ascension.It is a valuable source nof vitamin D which is a vital immune enhancing hormone ( although it is sometimes called a vitamin too) We need to expose our bodies to sunshine on regular basis sensibly to avoid burning though. It is out connection to Central Sun and to Life:)

Update:..showering after sun exposure and washing body with soap will remove the newly formed vitamin D from your skin. Vitamin d3 is an oil soluble steroid hormone. it’s formed when your skin is exposed to ultraviolet b (uvb) radiation from the sun (or a safe tanning bed). When uvb strikes the surface of your skin, your skin converts a cholesterol derivative into vitamin d3.

However, the vitamin d3 that is formed on the surface of your skin does not immediately penetrate into your bloodstream. It actually needs to be absorbed from the surface of your skin into your bloodstream.

The critical question then is: how long does it take the vitamin d3 to penetrate your skin and reach your bloodstream?

If you’re thinking about an hour or two, like i did until recently, you’re wrong. Because new evidence shows it takes up to 48 hours before you absorb the majority of the vitamin d that was generated by exposing your skin to the sun! Therefore, if you shower with soap, you will simply wash away much of the vitamin d3 your skin generated, and decrease the benefits of your sun exposure. So to optimize your vitamin d level, you need to delay washing your body with soap for about two full days after sun exposure.
Very few people are going to go two full days without bathing,however you can still take a nice hot shower - you really only need to use soap underneath your arms and in your groin area, so this is not a major hygiene issue. you’ll just want to avoid soaping up the major areas of your body that were exposed to the sun.
