Boy Developed 'Toasted Skin' Condition From Using a Laptop Every Day (arstechnica.com) 62

A medical report published earlier this week says a boy in the U.K. developed erythema ab igne, or "toasted skin syndrome," after resting a laptop on his abdomen for up to eight hours a day, often while it was charging. "The marks were described as being in a patch about 15 centimeters (six inches) wide, made of flat, reddish-brown 'interlacing lines forming irregular circles and a lace-like morphology,'" reports Ars Technica. From the report: Based on the appearance, the doctors started reconsidering some sort of bruising and started asking him more questions. This is when he mentioned that he was homeschooled and used a laptop for his schoolwork. He said he typically did his work by resting his laptop on his abdomen while he worked, sometimes for up to eight hours a day, and often while the laptop was charging. Then they understood what it was.

The doctors diagnosed the boy with erythema ab igne (EAI), which translates from Latin as "redness from fire" and is also sometimes called "toasted skin syndrome." This is a skin condition caused by repeated, prolonged exposure to low-grade heat -- heat not hot enough to cause actual burns. It's most often seen in adults, and common causes include using heating pads or hot water bottles for chronic pain or sitting too close to space heaters. Some people also develop it from certain occupational hazards, like glassblowing and metal work. EAI produces a lace-like rash, just like the boy's.

It's unclear how EAI develops exactly. But researchers hypothesize that chronic heat exposure leads to damage to superficial blood vessels and the release of red blood cells, forming the tell-tale red reticulated pattern. While the boy's condition looked ominous, the good news is that EAI is generally benign and reversible -- once you remove the heat source. For severe or long-term conditions, some pigmentation and scarring can remain. But the boy's parents checked back in over several months, reporting that the rash faded and then completely resolved. Hopefully, he also got some sort of laptop stand.

          Except it's the name itself which is a misnomer. No one is toasting anything, they are exposing themselves to above average temperatures for a prolonged period of time, temperatures I'm sure you've never given a second thought to and have exposed yourself to without a care in the past as well.

        • The issue, as described in the article, is prolonged exposisurecto long-term, low temperature heat, described as too low in temperature to actually burn skin - they give examples of prolonged use of electric blankets or hot water bottles.

      • Most people use laptops because in addition to your lap, every table and desk can be a computer desk: the cafe table, the kitchen table, work desks with docking stations, etc. Tables/desks also allow you far better posture.

          Far better posture than what? The whole notion of 90-degree upright posture being good for you Victorian-era pseudoscience. Sitting upright at 90 degrees is actually the most demanding position your back can be in. Your muscles have to constantly work to balance you against gravity. A 135 degree reclined position, such as in a recliner, is much better for your back [www.cbc.ca] than a 90 degree upright posture or a 70 degree forward slouch (e.g. your two typical "table positions"). When you're reclined, the chair takes a lot of the weight off your back.

          The whole concept of there being a "correct posture" is generally considered a myth today. There's very little correlation between static posture and the presence of back or neck pain. We're not bridges or columns designed to hold a fixed geometry; we're built for motion. Your body tells you what posture is best for you by your level of comfort/discomfort. Pain means "change positions, blood flow is dropping, tissues are tired". It has nothing to do with "your spine is misaligned" or anything like that.

          The one catch to sitting reclined is that your neck is looking more down, usually more than is comfortable for long periods; most people prefer their laptops somewhat elevated. For me, I have a footrest, so my legs are up and bent, and it's up from my thighs to my knees. Laptop trays / lap desks, which often have some padding at the bottom, also add some extra height.

              Yes. I've done both. A MacBook Pro that is nearly always used as a desktop replacement at home and away. A Mac mini and a small case for the mini, keyboard, and mouse. Often the keyboard and mouse never leave the case. Away being an employer's office, a collaborator's home or workplace, or a client's site. I've never had a problem getting a spare display that would be an improvement over the built-in. And better keyboard and mice are common too.

        This question assumes people only ever use their computer in one place. I have a laptop because I am constantly at different worksites. The computer is constant in my daily routines but the tables available to me are transient. However, I always use it at a table or a desk. Hunching over a device on my lap is not comfortable or efficient.

        If my work was strictly in one location, then yeah, a desktop would make more sense.
