Tablet Reading Before Bed Is Damaging To Sleep?
Posted on December 30, 2014 | By admin
According to research carried out by Harvard Medical School, reading on a back-lit e-reader or tablet before you sleep can put your health at risk. They also found that those who read from a tablet take longer to fall asleep compared to those who read from an actual book.
“The light emitted by most e-readers is shining directly into the eyes of the reader, whereas from a printed book or the original Kindle, the reader is only exposed to reflected light from the pages of the book. Sleep deficiency has been shown to increase the risk of cardiovascular disease, metabolic diseases like obesity and diabetes, and cancer. Thus, the melatonin suppression that we saw in this study among participants when they were reading from the light-emitting e-reader concerns us.” lead researcher professor Charles Czeisler told BBC News
