What is Sleep Disruption from Device Use?

Sleep disruption from device use occurs when smartphones, tablets, or computers interfere with sleep quality or quantity — through blue light exposure that suppresses melatonin, social media notifications that interrupt sleep, or the psychological stimulation that makes it hard to wind down.

Why It Matters for Families

The American Academy of Sleep Medicine recommends 8-10 hours of sleep for teenagers. Research shows that device use in the hour before bed — and especially keeping devices in the bedroom overnight — is one of the most significant contributors to teen sleep deprivation, which itself worsens academic performance, mental health, and physical health.

Warning Signs to Watch For

  • 1Keeps phone in bedroom or under pillow overnight
  • 2Checks phone first thing in the morning before getting out of bed
  • 3Consistently gets less sleep than age-appropriate guidelines recommend
  • 4Fatigue, irritability, or difficulty concentrating that improves on weekends

What You Can Do

The single most evidence-based intervention: charge all devices outside the bedroom overnight. This removes the temptation for late-night use and prevents notifications from interrupting sleep. If your child resists, establish it as a household rule that applies to adults too — model the behavior you're asking for.
