The Science of Why Smartphones Before Bed Is Harmful to Your Health
National Sleep Awareness Month Challenge: No Screen Time 1-hour Before Bed
This challenge invites you to avoid any kind of screen time one hour before bed for at least 15 nights this month. This means turning off anything with a screen—computers, tablets, phones, and television at least one hour before you go to bed. Make the hour before bedtime a time to reconnect with the people you love, talk about events of the day, read a book, or play a game—and get ready to shut down.
Studies show that screen time use before bed makes it more difficult to fall asleep and stay asleep during the night, and can negatively affect one’s daytime alertness. In addition to the mental stimulation associated with screen time, the light emitted from the screens themselves mimics daylight. This interrupts the body’s normal nighttime release of melatonin, which is a key ingredient for a good night’s sleep.
