Half of adults admit to falling asleep to the TV sometimes. It works as a distraction from racing thoughts — and then spends the rest of the night working against you.
What the TV does after you fall asleep
Flickering light suppresses melatonin even through closed eyelids, and sudden volume jumps — ads, explosions, laugh tracks — pull you into lighter sleep stages all night. Studies link nighttime screen light to more fragmented, shallower sleep.
Why it feels like it helps
A familiar show gives your mind something low-stakes to hold, which crowds out worry. That part is real and worth keeping — just not from a 55-inch light source.
The better swap
Keep the audio, lose the light: a sleep podcast or an audiobook with a sleep timer, or a white-noise machine for steady background. If you need a visual wind-down, give it a hard stop an hour before bed.
