Screen time can mess with the body's 'clock'
For a good night’s sleep, here is some expert advice: Turn off, turn in and drop off. Anyone who does the opposite — say, turning on an iPad or other similar electronic reader in bed — may have a harder time both dropping off to sleep and shaking that groggy feeling the next morning. That’s the conclusion of a new study. Lighting scientist Mariana Figueiro calls the study thorough. She also finds its results unsurprising. Her research has shown that spending even two hours on an iPad before bedtime can cut down the brain’s release of melatonin.
