of college-age women visit tanning salons regularly, in spite of increasing evidence that this practice is now considered the foremost avoidable causative factor in the rising incidence of melanoma.
Heliotherapy, or the therapeutic use of sunlight, was common to ancient Egyptian, Greek, and Roman civilizations. The Assyrians and Incas, among other populations, regarded the sun as a healthful god.
(Indoors, mankind relied for millennia on candles and oil lamps for light. Gaslight was invented in the 1790s and flourished in the 19th century until the development of commercial electric lighting and Tomas Edison’s reliable incandescent light bulb in the 1870s.)
In 1666 English physicist Isaac Newton demonstrated with prisms that clear white light is composed of seven colors that make up the visible spectrum: red, orange, yellow, green, blue, indigo, and violet. In 1801 German physician Johann Ritter discovered “ultra-“violet light, energy beyond the violet end of the visible spectrum of light.
The sun emits ultraviolet radiation. Long-wave ultra-violet light, or UVA, which is not filtered by the earth’s ozone layer, penetrates deeply into the skin causing disruption of DNA that can lead to cancer and aging of the skin. Medium-wave ultraviolet rays—or UVB—are mostly absorbed by the ozone layer and atmosphere. UVB helps form Vitamin D in humans but causes skin burns.
In 1903 Danish physician Niels Ryberg Finsen was awarded the Nobel Prize in Medicine and Physiology for his use of concentrated beams of ultraviolet light in the treatment of the skin condition lupus vulgaris. The medical applications of ultraviolet radiation increased with the invention of the ultraviolet lamp at the turn of the 20th century. During World War I a German physician Kurt Huldschinsky used ultraviolet-emitting lamps in the successful treatment of children with the bone disease rickets. Researchers later showed that the disease was caused by a deficiency of Vitamin D. The terms “health lamp” and “sun lamp” were introduced to treat a variety of ailments from depression to diabetes.
Unfortunately, beginning in the 1920s the use of ultraviolet lamps in medical treatments also led to the promotion of these devices for the cosmetic purpose of getting a tan, in spite of the harm that such non-medical applications could cause. Through the decades, manufacturers of UV lamps reduced but did not eliminate the amount of emitted UVB light. The world’s first tanning salon opened in Germany in 1977, and the phenomenon spread to the United States the following year. There are now more than 18,500 tanning salons in the US.
For centuries, a pale complexion was cultivated by the aristocracy to distinguish it from ruddy-faced common laborers.
Beginning in the late 18th century, the Industrial Revolution shifted the workforce from farming to factories often in dense urban settings. The lack of sun exposure was found to cause health problems, notably the lack of Vitamin D that could result in the deforming bone disease rickets. The artificial ultraviolet light lamp was invented in the 1890s and used to prevent vitamin D deficiency in children and factory workers alike.
Such beneficial applications were touted in medical journal advertisements for the next fifty years (and artificial ultraviolet light therapy still plays a significant role in the treatment of psoriasis).
The term “sun lamp” was coined in the 1920s, and Parisian fashion designer Coco Chanel helped popularize tanning as a mark of the leisure class who could vacation on the Riviera and did not toil in factories. Although an advertisement for a sun lamp in the 1930s would claim that it was safe for the whole family, by then it had been discovered that laboratory rats exposed to ultraviolet light bulbs developed skin cancer.
Sun lamps were aggressively promoted in major consumer magazines by General Electric and Westinghouse throughout the 1940s and 1950s in advertisements that highlighted the alleged allure of a tan while downplaying health claims. Outdoor tanning became increasingly popular in the 1960s, but in the late-1970s indoor tanning emerged in Europe before being introduced in the US in 1979. The incidence of melanoma has been steadily increasing ever since. Today there are more than 18,500 commercial tanning salons.
According to the International Agency for Research on Cancer, women who use tanning beds even once are six times likelier to develop melanoma in their 20s than women who have never used a tanning bed.

Although virtually all college students who use tanning beds are aware that the devices increase the chances of getting skin cancer, most students also believe that everything causes cancer and that tanning bed use is no more risky than many other habits.
Upwards of 31%-39% of students who use tanning beds may be addicted to tanning.
College newspapers are a key advertising medium for tanning bed salons. Literature reviews, internet searches, and personal communications have failed to identify any college newspapers that have either stopped accepting ads for commercial tanning salons or editorially urged students to avoid tanning beds.
Not only does the tanning bed industry downplay the magnitude of risks from the use of these devices (akin to the tobacco industry’s denial for decades of the dangers of cigarettes), but it also insists that they provide healthful benefits such as increased Vitamin D.
Tanning beds emit 12 times more ultraviolet A radiation (UVA, with a longer wave length that penetrates the skin more deeply, disrupts DNA, and causes premature aging and wrinkling) than sunlight.
of tanning bed radiation released is ultraviolet B. UVB burns the upper layers of the skin and increases the chances of getting skin cancer.

In the US 17 states and the District of Columbia have enacted laws that ban the use of tanning beds by minors under 18. The notorious case in 2012 of New Jersey’s “tanaholic mom,” who took her 5-year old child with her to the tanning salon, led to the passage in 2013 of a ban in that state on the use of commercial tanning salons by children and teenagers. In Australia, which has the world’s highest incidence of melanoma, commercial tanning bed establishments have been banned in all states and territories since 2016.
