Does Screen Time Impact Your Sleep?

Your Phone Might Be Your Sleep's Worst Enemy

That late-night scroll feels harmless, but the science tells a different story. Evening screen use can delay how quickly you fall asleep, cut into your restorative REM sleep, and leave you groggy the next morning - even after a full eight hours in bed

The culprit is twofold. Blue light from screens suppresses melatonin, the hormone that signals it's time to sleep, while stimulating content keeps your mind alert and wound up right when it should be settling down. Together, they create the perfect storm for a restless night.

The effects reach further than tiredness, too. Disrupted sleep from screen exposure is linked to poorer memory and decision-making, mood and mental health impacts, metabolic changes, and a weaker immune response — a cascade that builds quietly night after night.

The good news? A few simple changes to your evening routine can make a real difference, often within the first week. Discover what the research reveals about screens and sleep — and the easy, evidence-based steps you can take tonight.
