Remember the first night with your iPad and you find yourself tired but can’t figure out the perfect side of the bed? According to a report by LATimes reading an iPad before bed time may affect sleeping habits.
Compared to the Nook and Kindle which uses E-ink technology and doesn’t use light, the iPad like your TV, and laptop uses LCD. Exposure to such artificial light before going to bed blocks your body’s secretion of melatonin – a signal to the brain in response to darkness dictating your body that it’s time to sleep.
No wonder I can’t sleep when the light is on. According to Frisca Yan-Go – Director of UCLA Sleep Disorder Center, Sta Monica:
Light-emitting devices, including cellphones and yep, the iPad, tell the brain to stay alert. Because users hold those devices so close to their face, staring directly into the light, the effect is amplified compared with, say, a TV across the room or a bedside lamp
So next time you go to bed, give yourself a favor by not reading an ebook on the iPad. Perhaps we still need Kindle afterall?
