That's according to a new study -- a teeny, tiny study -- at Rensselaer Polytechnic Institute's Lighting Research Center. RPI found that looking at a backlit screen, like those on iPads and other tablets, can lead to sleeplessness.
Results of the study, titled “Light level and duration of exposure determine the impact of self-luminous tablets on melatonin suppression,” were recently published in the journal “Applied Ergonomics.” It was funded by Sharp Laboratories of America.
Another researcher suggests that teenagers and young adults, who “tend to be night owls,” may be particularly sensitive to the tablet light exposure.
What’s a bedtime reader to do? These results suggest avoiding backlit tablets and reaching for something else. A text-only Kindle, for example. And paper books, while old fashioned, work perfectly.
Happy reading, and happy sleeping.
