The pursuit of bronze skin? Careful drying addictive

Posted Apr 01 2012 4:44am

Also tanning addiction?Recent experiment found that, beautiful dark skin and frequent use of tanning beds is likely to be as addictive like a drug addiction.
A recent study showed that frequent use of tanning beds, the brain is similar to drug addiction changes occur.

Editor's Note: tanning beds is an issue of UV equipment, UV is generally 97% of UVA and 3% of UVB sunlight, less UVC is.Ordinary tanning beds have several fluorescent lamps, the light emitted by simulated sunlight spectrum.

Scientists had speculated that ultraviolet radiation is addictive.This time it is the first time scientists have people lying on the tanning bed to spy out their brains.The researchers found that when subjects sunbathing, several addiction related region in the brain are activated.The results will be published in the latest issue of Addiction Biology ", may help explain why some people continue to sunbathe, despite its risks - skin cancer, premature aging and wrinkles.

"This fully demonstrates that the brain will react to UV irradiation, and is in the area related to addiction." Professor of psychiatry at the University of Texas Southwestern Medical Center, one of the authors of the report of this study, Dr. Bryon Adinoff said.These areas, especially the striatum, is often observed when using the drugs or the intake of high calorie foods (like sugar) is activated.

While sunbathing can cause skin cancer warning is already a lot, but tanning is still popular.Each year, nearly 30 million Americans receiving indoor solarium, a daily average of over one hundred people participated in the tanning salon.Those who
Cabas Lin Et Paillettes  frequent tanning said  they are just like their dark skin. 

But in recent years, scientists began to suspect willful neglect of regular fatal side effects of UV exposure is a sign that it suggests frequent tanning motivation to not stop at skin level (but the brain).They suspect habitual tanning is an addictive behavior.A 2005 study also showed that a large proportion of sunbathers meet the psychiatric definition of drug abuse disorders, which is derived based on their answers to a slightly modified test, this test was originally usedthe diagnosis of alcohol addiction.

But Dr. Adinoff and his colleagues decided to do further research.Recruited a small group of people from the tanning salon, these people said at least one week to do three times the sun, and to maintain the brown skin is very important for them.They agreed to be injected with a radioactive isotope, the researchers will use this to monitor the solarium how it affects their brain activity.

These subjects first underwent a course of ordinary sunbathing, and then accept a course of UV solarium "- the researchers used a special filter device to filter out ultraviolet light.Subjects and have not been told different.

In the solarium treatment after brain scans showed that when subjects were exposed to ultraviolet light, a few key areas of the brain is illuminated: the dorsal striatum, the left 
Sac Paillettes Blancanterior Island, part of the orbital cortex - all these areas andin addiction.UV filter out these areas of activity intensity is greatly reduced. 

The researchers also found some evidence that these people are actually vaguely aware of them accepted the adulteration of sunbathing, there is no exposure to the usually used doses of UV.After each treatment, subjects will be asked about feelings, they received a really solarium, sun enough.Those who do not know that ultraviolet rays are filtered out, the desire to once again the sun and accepted before the experiment.

Adinoff, Dr. said: "these people are still like a real ultraviolet radiation treatment, they always have a way to distinguish between their acceptance of sunbathing is true or not," he said, the study showed that some people are really addicted to tanningphenomenon, a fact also supports this conclusion - many people who receive long-term sunbathing, very tough when to stop or just reduce the tanning treatment.(Similar to smoking cessation and alcohol withdrawal reactions.)

It is said that his study is inspired by a dermatologist colleagues, "she always complained to me, some skin tan very beautiful tan young looking for her to see a doctor, each time, once she ruled out the skin cancer, theywill go back and re-tanning. "
