Warm laptops can damage laps, reports say
CHICAGO – Have you ever worked on your laptop computer with it sitting on your lap, heating up your legs? If so, you might want to rethink that habit.
Doing it a lot can lead to “toasted skin syndrome,” an skin condition caused by long-term heat exposure, according to reports.
In one recent case, a 12-year-old boy developed a sponge-patterned skin discoloration on his left thigh after playing computer games a few hours every day for several months.
“He recognized that the laptop got hot on the left side; however, regardless of that, he did not change its position,” Swiss researchers reported in an article published today in the journal Pediatrics.
Another case involved a Virginia law student who sought treatment for the mottled discoloration on her leg.
Dr. Kimberley Salkey, who treated the woman, was stumped until she learned the student spent about six hours a day working with her computer on her lap. The temperature underneath registered 125 degrees.
That case, from 2007, is one of 10 laptop-related cases reported in medical journals in the past six years.
The condition also can be caused by overuse of heating pads and other heat sources that usually aren’t hot enough to cause burns. It’s generally harmless but can cause permanent skin darkening. In very rare cases, it can cause damage leading to skin cancers, said the Swiss researchers, Drs. Andreas Arnold and Peter Itin from University Hospital Basel. They do not cite any skin cancer cases linked to laptop use, but suggest, to be safe, placing a carrying case or other heat shield under the computer.
