What do we know about the health effects of laptops?
Unfortunately, laptops are new enough that more research is needed to truly explore their impact on health, says Neil Korman, a professor of dermatology at the University Hospital of Case medical center in Cleveland. But you should know that permanent damage to your skin can happen.
“The temperature [of a laptop] can cause a patterned discoloration on your skin, called erysipelas -- which literally means, ‘redness by fire,’” Korman says.
The skin discoloration associated with laptop-to-skin contact is similar to what one would suffer from resting their legs on a space heater, or getting too close to an actual fire. While Korman promises it’s an “uncommon phenomenon,” and not life threatening, the discoloration that does happen is permanent. Meaning it’s for-ev-er.
