Hold too long on the laptop resting on the legs can cause stains on the skin with an unusual sponge effect. This is what happened to a twelve year old, whose case appears in the journal Pediatrics. The boy resorted to the care of doctors for several months after he had played on the computer, keeping always on the same leg. The doctors call this phenomenon as "syndrome toaster", comparable to the effects of prolonged sun exposure. The base of a laptop can reach, in fact, even the 52 ° and, experts point out, cause permanent cosmetic damage, but harmless. The same may happen with the use of hot water bottles.
