Exposure to Sun and the Dangers of Tanning

It is widely known that protected sun exposure is important for your overall well-being, but over exposure can lead to skin cancer, a condition that is certainly not beneficial to your health. For this reason doctors stress the importance of taking steps to avoid sun damage.

Vitamin D From Food or Sunlight

For a long time it was a generally accepted fact that sunlight was vital for your body’s processing of vitamin D. However, today, many food manufacturers offer foods that are fortified with vitamin D since it does not come naturally in nearly all foods. Therefore, basking in the sun is no longer as essential for the intake of vitamin D. This fact would be looked upon with some reserve by individuals who would prefer to be outdoors playing their favorite game than indoors using exercise machines. Fortunately there are many ways to shield yourself from the harmful effects of the sun while engaging in your preferred outdoor activity.

The Harmful Effects of Ultraviolet Radiation: UVA, UVB, and UVC

Wrinkling and skin aging are brought about by UVA radiation and may eventually lead to a dangerous form of skin cancer known as melanoma. Ultraviolet B radiation (UVB) is no less perilous, given its ability to cause sunburns, cataracts and impact the immune system. Skin cancer is also brought about, with Melanoma thought to be linked to serious UVB sunburns. Ultraviolet B radiation is mostly absorbed by the ozone layer; however, a sufficient amount goes through causing significant damage. The most harmful of all, UVC rays, are fortunately blocked by the ozone layer and prevented from getting to the earth’s atmosphere. It is important to note that people with fair skin burn more easily. Moreover, those of darker complexions are less at risk than blonds or brunettes having green or blue eyes.

Sunless Tanning: An Alternative to sun bathing

Many persons would like to have a sun-induced glow while wanting to avoid the harmful effects of excessive sun exposure. Sunless tanning products, (self-tanners), are known for treating your skin to a tanned look minus that dreaded ultraviolet rays. These products are generally obtained in the form of sprays, lotions, creams and gels. Specialized tanning services are also available at salons, spas and commerce alike. Dihydroxyacetone (DHA), is the active ingredient found in the majority of sunless tanning products and contributes to a darken skin appearance. It is worth mentioning here that if you happen to be outdoors, a sunscreen would be necessary since sunless tanning products do not include them.

Melanotan is another method for fake tannig, which is a substance that has grown in popularity, especially amongst bodybuilders and ironically fitness types. It is a peptide product available in two melanotan variants and can be administered using a nasal spray or injection for accelerated tanning results. It is important to note the risks and possible side effects of melanotan usage and counterfeit products. If you are going to use it, ensure you obtain it from a reliable source.

Although the risks and dangers associated with over exposure to sunlight are evident, many researchers also point to the benefits attained by being exposed to a little sunlight. Sunlight helps in the production of melatonin (produced by the brain pineal) and studies have indicated it can lead to healthy sleep. And apart from the production on vitamin D, it enhances blood circulation through the expansion of blood vessels in the skin, nourishing the cells with added oxygen and nutrients. It also makes a healthy heart by lowering heart rate and reducing blood pressure.
