You bet it can! Getting a good night sleep starts with turning off all electronics at least an hour before bed. Seems like an easy thing to do…but, if you’re like most people, your phone sleeps with you! Smartphones and tablets are the devices most likely to be used in the bedroom. These devices inadvertently affect the quality and duration of your sleep. This is because they have bright light emitting diodes, which interfere with melatonin, a hormone that controls the sleep-wake cycle. So how can you check your mobile device without affecting a good night sleep? Try dimming the brightness setting of the smartphone or tablet and holding the device at least 14 inches from your face while using it. Recent research has found that doing this has reduced the risk of the brightness interfering with melatonin and affecting sleep.
