Smartphones May Hinder a Good Night's Sleep

If you’re in need of a good night’s sleep, it might be wise to give your smartphone a rest from time to time.

New research suggests that the light from smartphones, especially before bedtime, may affect how long and well you sleep. Sure, we know that screen time right before bed is bad for sleep. And turns out, using your smartphone late at night also makes you feel depleted in the morning, thereby making you less focused and engaged at work.

How Smartphones Hurt Sleep

Blue light makes the brain think it’s time to wake up, just as you’re getting ready for bed. Smartphones and tablets disrupt sleep, in part, because they emit what’s known as “blue” light. This light is picked up by special cells behind our eyeballs, and it communicates to the brain that it’s morning. Red light, meanwhile, signals that it’s time to go to sleep.

The new study from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute believe the displays cause melatonin suppression.

Melatonin is the chemical that controls our body clock. All of this blue light suppresses melatonin, a hormone that helps with sleep timing and circadian rhythms. At night, our melatonin levels are supposed to rise in anticipation of sleep.

They believe teens are particularly susceptible to the problem.

‘We recommended dimming these devices at night as much as possible in order to minimize melatonin suppression, and limiting the amount of time spent using these devices prior to bedtime.’
