Tanning is Not Safe - New Research Declares It Unhealthy

If you thought tanning is safe - think again, for a new survey has revealed that nothing could be further away from the truth.

The online survey "Suntelligence: How Sun Smart is Your City?" by the American Academy of Dermatology (Academy) sets the record straight on some of the most common myths and what people believe to be true about tanning and sun protection.

Tanorexia- Addiction to Tanning Can be Extremely Dangerous
Tanorexia, or an addiction to tanning, can be harmful, according to experts.

The poll covered more than 7,000 adults nationwide to determine their knowledge, attitudes and behaviours toward tanning, sun protection and skin cancer detection.

Myth: Some types of ultraviolet (UV) rays are safe for your skin.

The survey found that only about one-third (35 percent) of respondents correctly answered false to this question.

Tanning Bed Users Might Become Addictive, Warn Experts
Individuals who use UV tanning beds may meet the criteria for addiction and are more likely to suffer from anxiety symptoms and substance abuse, a study released Monday said.

Fact: Sunlight consists of two types of harmful rays: ultraviolet A (UVA) rays and ultraviolet B (UVB) rays. UVA rays (which pass through window glass) penetrate deeper into the thickest layer of the skin known as the dermis. UVA rays can cause suppression of the immune system, which interferes with the immune system's ability to protect a person against the development and spread of skin cancer. UVB rays are the sun's burning rays (which are blocked by window glass) and are the primary cause of sunburn.

"Quite simply, all forms of UV exposure, whether from natural sunlight or artificial light sources found in tanning beds, are unsafe and are the No. 1 preventable risk factor for skin cancer," said Dr. Draelos.

Teen Boys Turn to Diet Pills, Body Waxing and Tanning Under Peer Pressure
A new study has claimed that peer pressure is making teen-aged boys use tanning booths, take diet pills and have their bodies waxed, even though they know it's unhealthy.

Myth: Getting a base tan is a healthy way to protect skin from sun damage.

Only 48 percent of respondents knew this statement was false.

Ban Unsupervised Tanning Salons, Welsh Government Advised
The National Assembly for Wales' Health, Well-being and Local Government Committee have advised the government to ban unsupervised tanning salons.

Fact: A tan is a sign of damage to the skin from UV radiation. Every time a person tans, the skin becomes damaged and this damage accumulates over time. This accumulated damage, in addition to accelerating the aging process, also increases a person's risk for all types of skin cancer.

"A base does very little to protect your skin, and since tanning damages the skin, getting a base tan could do more harm than good." said Dr. Draelos. "The only way to prevent sunburn is to protect your skin through using sunscreen, wearing protective clothing and seeking shade."

Myth: It is smarter to tan indoors using a tanning bed.

More than half (63 percent) of respondents knew that this statement was false.

Fact: The United States Department of Health and Human Services and the International Agency of Research on Cancer panel has declared UV radiation from the sun and artificial light sources, such as tanning beds and sun lamps, as a known carcinogen. Indoor tanning equipment, which includes all artificial light sources, emits UVA and UVB radiation. It has been shown that the amount of the radiation produced during indoor tanning is similar to the sun, and in some cases might be stronger.

"Despite claims by those in the tanning industry that UVA rays used in indoor tanning are safer because they do not cause sunburn, scientific evidence proves that this claim is untrue," said Dr. Draelos. "UVA rays cause deeper skin damage and are linked to melanoma, the most serious form of skin cancer. In fact, studies show that melanoma is increasing faster in females 15-29 years old than males in the same age group. And in females 15-29, the torso is the most common location for developing melanoma, which we suspect is due to high-risk tanning behaviors - including indoor tanning."

Myth: A sunscreen with a Sun Protection Factor (SPF) 30 provides twice the protection as an SPF 15.

Only 21 percent of respondents knew this statement was not true.

Fact: Contrary to popular belief, UVB protection from the sun's burning rays does not actually increase proportionately with a designated SPF number. For example, an SPF of 30 screens 97 percent of UVB rays, whereas an SPF of 15 screens 93 percent of UVB rays, and an SPF of 2 screens 50 percent of UVB rays.

Dr. Draelos also noted that inadequate application of sunscreen may result in a lower SPF than the product contains.

"Regardless of the SPF you use, wearing sunscreen should not provide a false sense of security about protection from UVB exposure," said Dr. Draelos. "No sunscreen can provide 100 percent UVB protection, but using a higher SPF provides greater UVB protection than a lower SPF. It's important to remember sunscreen must be reapplied regularly and be part of an overall sun-protection plan that includes hats, sunglasses, protective clothing and seeking shade."
