Let’s face it, we all love a good tan, that is why we spend a lot of time sun bathing trying to get our skin brown, but what if its winter, no sun but you still want that awesome tan? Or you cannot afford that sunbed for sale that you have seen?Or the tanning in the sun is taking too long and you need instant results. Well worry not scientists are way ahead of you. They invented the Sun bed as the English call it, what you may know as tanning bed. This basically works as an artificial sun to give you a faster tan than the natural light. How exactly does it work you ask? There is a lot of science behind the making of this sun rays so to speak.
Welcome to tanning bed 101.
The tanning bed works by releasing ultra violet radiation (UVR) onto the skin to produce a tan. See the sun produces UVR in 3 wave forms A, B and C named according to o their length A being the longest and the other two follow respectively. UVC is however not used in tanning beds while UVA being dominant at about 95% and UVB at 5%.
Tanning beds use fluorescent lamps known as tanning lamps that have phosphor blends that make it possible for them to release UV in a spectrum almost similar to the sun. There are several types tanning lamps but they can be classified into 2 major categories; high pressure which are more expensive and generate mainly UVA rays and low pressure ones which are more common.
One lays on a tanning bed and when the rays are released into the skin they stimulate the melanocytes on the upper skin to produce melanin which gives you that glowing brown skin, the more the rays the more the tanning on the skin. The reason why tanning beds work faster than the natural sun light is merely because of distance, the sun is millions of miles from us while the rays from the tanning bulbs are just next to the skin hence a faster and tanner look.
Tanning beds are awesome alright but they don’t come without health effects. UVB lights are known for causing skin cancer such as melanoma and although this is also gotten from natural sunlight most tanning beds produce more UVB light than the sun ray. UVA rays that are dominantly used are associated with skin damaging such a wrinkling, age spots and fine lines. People who visit tanning salons are therefore more expose to skin problem as opposed to those who choose to use the normal process. It is therefore advisable to use the tanning beds wisely and avoid over using them to avoid having to suffer later on. A good tan is not worth your health and life.
The tanning bed despite the many criticism we have to agree is a great invention to the cosmetic industry and now that you are aware of its pros and cons you can choose whether or not to make that visit to a tanning a salon. The decision is entirely up to you.
