Sun Exposure And Skin Cancer

The sun's rays are an item that can produce skin cancer if you expose irrationally to their action. In fact, this type of cancer is becoming more common, in part due to the weakening of the ozone layer, allowing more forceful action of the ultraviolet rays.

But sunlight is a radiation type without which the life could not exist on our planet. The composition of this light is what makes it so healthy and at the same time deadly if we abuse of it.

First, we must consider the sunlight  spectrum, infrared radiation (IR ).

These waves with lower frequency vibration
 The action of these invisible waves is to heat the bodies with which they collide, being responsible for the solar heat. In this way stimulate skin sweat glands action and dilate peripheral blood vessels.


With a higher vibrational frequency, we find the visible spectrum. It is formed by a combination of waves from different frequencies corresponding to all the colors visible to humans . In the upper part of the spectrum are the ultraviolet ( UV) , responsible for skin pigmentation and erythema or sunburn.


The ozone layer of the atmosphere is primarily responsible for filtering these ultraviolet rays, which can deduce that actually due to the regression of this natural protection, the sun strikes the surface of our planet at a rate abnormally higher of said rays.


Sunlight is a source of health if used rationally . The different vibrational frequencies contained in the rays are perfectly and naturally balanced , except perhaps by excessive concentration of ultraviolet rays produced by the weakening of the atmospheric ozone layer.

Even so, the sun's rays are still necessary to allow the perpetuation of life on our planet, with its salutary effects remain undeniable.


Skin cancer risk
The use of narrow-spectrum lamps ( infrared , or ultraviolet lighting ) , to the produce a totally unbalanced light in composition, do not have the salutary effects that the sun can provide applied correctly . It was possible to relate the occurrence of skin cancers using artificial  ultraviolet lamps. This method of tanning is already banned in some countries.


As we said, the sun used without any rationality or caution can be harmful and cause skin cancer . Later we will study how to apply sun exposure therapy safe and avoid its harmful effects.
