One of the principal effects of tanning beds, also known as sunbeds, which are devices that emit ultraviolet radiation, is to induce an increase in the melanin in your skin, thereby creating a tan. A German scientist Friedrich Wolff introduced indoor tanning equipment to North America in 1978. Since then, indoor tanning beds have increased in volume to the extent of becoming one of the best selling cosmetic devices in the world. The estimated value of the salon tanning market in the US alone is said to be $5 billion annually.
Today, modern tanning bed booths are said to have about 95% ultraviolet A (UVA) light and 5% ultraviolet B (UVB) light. Thus one of the effects of tanning beds is a much higher concentration of UVA than ordinarily received by the sun. UVB rays have long been linked to sunburns and skin cancer, while UVA was associated more with aging of the skin as they penetrate deep into the skin, destroying skin fibers and damaging elasticity. Scientists pretty much agree that UVA rays are less likely to cause sunburns, but that they are still linked to malignant melanoma, damage to the immune system, weakening of the skin's inner tissue, and to other types of skin cancers.
The popularity of tanning beds combined with these alarming facts about tanning bed dangers has created an ongoing debate over the last few years between industry and several medical organizations on the effects of tanning beds. Both medical associations and government organizations have associated tanning beds with squamous cell carcinoma and melanoma, which are skin cancers, as well as ocular melanoma, which is an eye cancer. According to the FDA (US Food and Drug Administration), the International Agency for Research on Cancer publicly states that it considers tanning beds to be carcinogenic to humans.
The World Health Organization (WHO) states that a main effects of tanning beds is the loss of elasticity in the skin, which leads to wrinkling and premature aging of the skin. In addition to this, if not controlled sufficiently, the UV rays causing the skin to tan can also cause eye problems such as cataracts and photo-conjunctivitis. Also, excessive amounts of UV exposure can cause a drop in immunity, making the person more susceptible to becoming ill with infectious diseases.
Tanning bed supplies today provide a huge choice, both for commercial and for domestic use. Sometimes the tanning beds have settings that can be adjusted for the amount of time desired as well as the amount of UV rays produced. In essence, this allows for a much more controlled experience than just sitting outside in the sun. But if abused and overdone, rather than controlled, the results can be devastating tanning bed burns!
So, when tanning bed safety is administered and controlled properly, the effects of tanning beds can actually be advantageous to ones' health. They have been used medically for decades to assist in curing skin problems such as dermatitis, psoriasis and eczema as well as other health problems such as rickets, vitiligo and lupus. In this respect there are many great tanning bed tips to be found, either at the salon you visit or via health based web information.
Also, UVB is seen in an increasingly good light ray as it is the source of Vitamin D, which is being heralded for an increasing number of health benefits. UVA on the other hand, actually destroys Vitamin D in the skin. So the optimum is to have a tanning bed with a much higher percentage of UVB than UVA. If you manage to find an old fashioned bed, they are said to contain a higher percentage of UVB. Another recommendation is to avoid high pressure tanning booths to contain your exposure to the harmful effects of tanning beds.
Despite warnings from medical or government authorities, consumers continue to flock in the millions every year to tanning salons or use their own tanning beds in their homes. In today's fast paced, on-the-go society, there is a rising demand for healthier lifestyle options and a need for daily stress management and relief. Tanning is seen to provide just this relief. Tanning bed products aim to increase this experience with such things as 'tingle' sensations in the lotions provided. Some tanning bed lotions have added aromatherapy benefits, whilst most will have an appealing perfume.
The American Academy of Dermatology published a study in July 2004 showing tanning booths to be addictive. This would explain to some degree why people keep going back for more long after they have acquired the tan they came for and despite knowing how bad it may be for their skin.
Surveys have shown, however, that teenage girls account for the biggest percentage of users of these beds, particularly in Western countries. There is also a trend for people to use tanning beds when living near seaside resorts or outdoor amenities, even though they have the natural sun at their disposal for tanning.
Another interesting set of studies on the effects of tanning beds has focused on the damage caused to the eye. One such study indicated that UV radiation levels to the eye could be over 100 times greater in the tanning booth than with outside natural sunlight. Corneal burns, cataracts, and occasionally retinal damage have been known to occur. For this reason it is important to wear eye protection if using a tanning booth. It is also recommended that you make sure the eye cover is new or clean to prevent potential infection. Otherwise, perhaps it is better to take your own eye protection cover. Wearing sunglasses or keeping your eyes closed is not sufficient at all.
Because there are no laws governing the use of indoor tanning beds, people are free to use them as long and as often as they like. Keep in mind that the majority of tanning salons do have restrictions about usage but these are rules set up by the salon, not the government.
