The evening use of iPads and other devices with built-in LED-these can interfere with our biological clock, by interfering with the hormone melatonin.
A team of researchers from Brigham and Women’s Hospital in Boston found that blue light LED-these can cause the next day will be sleepy. Of course, if the iPad use at bedtime. Studies have shown that people who use tablets and e-book readers fall asleep later than those in the same circumstances, read classic books.
– We found that the use of these devices for backlight LED blue light LED disrupts the natural rhythm of the biological clock. Participants experiment that uses e-books were harder to fall asleep in the evening were just less sleepy, their body gave off less important for sleep hormone, melatonin, biological clock is delayed, and therefore, in turn, were more sleepy in the morning – said co-author of the work, the doctor Anne-Marie Chang.

Even before it was known that blue light with a wavelength of approx. 450 nm may interfere with the functioning of the biological clock. So far, however, no one has examined the impact of the use of iPads on the quality of REM sleep. Similar effects also causes the light of other tablets, smartphones and laptops. For the quality of our sleep, much better to reach for the traditional book.
