Tanning booth

A tanning booth is a device that emits ultraviolet radiation, usually for the purpose of a cosmetic tan. They are very similar to a tanning bed, but the design is such that it is intended to be used while standing up, rather than lying down.

Tanning booth.

Tanning booths generally use 160 watt VHO (Very High Output) or 180 watt VHO-R (Very High Output with Reflector) lamps which is similar to the Mediterranean sun during mid day. Some less expensive systems use standard 100 watt HO (High Output) or RUVA (Reflector UVA) lamps. Many people confuse "VHO-R" and "VHR ", with the latter being a trademark of Cosmedico lamps for their versions of the VHO-R lamps.[1] The average tanning booth has from 32 to 56 lamps and uses a 10 to 15 minute tanning session time.

Comparing to tanning beds[edit]

Tanning booths are similar but distinct from tanning beds in that they are vertical rather than horizontal, but there are generally other differences as well. Most tanning booths use the higher watt VHO and VHO-R lamp, which consume 160 and 180 watts respectively, while most tanning beds use 100W HO lamps, although there are many exceptions. Tanning booths are often said to give the user a better tan because it is easier to move while tanning, and most have handles above the head, which makes tanning under the arms and on the sides easier. Most booths do not have a reflector system behind the lamps because they use the VHO-R lamps, which have a more effective reflector built inside the lamp itself. This forces all the light to be focused out the front of the lamp, reducing lost UV from phase cancellation. This is where two opposing waves (in this case, UV) that are out of phase with each other partially cancelling each other out, resulting in a loss of net UV that reaches the user.

Another difference that is not as obvious is that there are no pressure points when tanning inside a booth. A person using a tanning bed is supported by the acrylic, and in these areas the blood flow is reduced. Melanin production is somewhat reduced in these areas leading to a tan that is not completely even. For most individuals, this isn't very obvious but certain individuals will experience circular areas with slight but noticeably less tan in those pressure areas. Most (but not all) tanning booths do not have acrylics and instead use a wire mesh to protect the user from the lamps. Although this results in a somewhat higher UV transmission, it does not offer the same protection that a solid acrylic sheet offers.

It is very common for tanning booths to have shorter exposure times than tanning beds. This is partially due to the more common use of the 160-180 watt lamps, which produce more UVA and UVB than a 100w lamp. Another factor is the choice of most manufacturers to use a higher UVB style lamp. Because the FDA regulates exposure time using a method that biases against UVB (for all tanning units), this reduces the average exposure time from the traditional 15 to 20 minutes found on most tanning beds, to 10 to 15 minutes, with some booths even lower. Tanning booths are subject to the same regulations as tanning beds, including posting the suggested time exposure in a conspicuous place on the tanning unit, and in the original owners manual.

Common use[edit]

Tanning booths are not as common as tanning beds because they generally cost significantly more and because they are not as comfortable, as you tan standing up. This limits the adoption of tanning booths over tanning bed particularly in the residential market, where comfort and price are primary considerations for purchasing. There are no published statistics on the number of booths sold versus tanning beds, as all US tanning bed manufacturers are privately held companies and these numbers are considered proprietary. Anecdotal evidence would indicate that less than 10% of the tanning units in professional tanning salons are booths.

One reason professional salons may choose a booth over a bed is the amount of space required, as a booth requires significantly less square footage than a bed. Also, many booths have the option of a dressing room attached to the unit, which means the salon owner doesn't have to build a special room to house the unit, reducing their initial cost to install. This often offsets the higher cost of the unit.

Risks[edit]

As with any device that emits ultraviolet, there are risks, especially with overexposure. Tanning booths are not safer than tanning beds, as the basic mechanics are the same. See sun tanning for a more complete list of the potential hazards associated with tanning indoors or out.

UV Tanning substantially raise risks of skin cancer, including melanoma.[2]

Overexposure to ultraviolet radiation is known to cause skin cancer,[3] advance skin ageing and wrinkling,[4] mutate DNA,[5] and reduce immune system response.[6] Frequent tanning bed use triples the risk of developing melanoma, the deadliest form of skin cancer.[2] Children and adolescents who use tanning beds are at greater risk because of biological vulnerability to ultraviolet radiation.[7]

The US Public Health Service states that UV radiation, including the use of sun lamps and sun beds is "known to be a human carcinogen."[3] It further states that the risk of developing cancer in the years after exposure is greatest in people under 30 years old.

Regulation[edit]

Further information: Tanning bed § Regulation

Regulation of tanning using ultra-violet lamps has increased, particularly for people under 30 years of age, due to the greatly increased risk of skin cancers.[7] Some jurisdictions, i.e. the United Kingdom (except for Northern Ireland),[8] California,[9] and Australia,[10] have banned the use of tanning booths and beds by those under eighteen.

In February 2012 the state Government of New South Wales in Australia announced its intention to ban new solariums (including tanning beds), starting in 2014. This excludes the use by medical professionals or privately owned system. [11] In Queensland in Australia, announced a ban on commercial solariums and tanning beds starting in 2013.[12]
