One of the biggest drawbacks of using a laptop on your lap is the fact that it can make you feel like an oven. Well, some people claim that there could be health side-effects as well.
London’s Daily Mail claims that “girls as young as 12 are being diagnosed with nerve damage” from slouching over laptop screens. The main problem appears to be bad posture when using the laptop on your, uh, lap — hunching over in this way apparently causes chronic back problems in all sorts of people.
There’s never been a published report regarding this theory, so take it with a grain of salt. Better posture = better health.
