"People sleeping with the TV on is a very 3common thing."

Psychologist Chivonna Childs with Cleveland Clinic says there's no blue light filter on a TV like there is now on cell phones and that can 4negatively 5impact your sleep.

"The blue light kind of 6reminds us of the sun, so it 7disrupts our 8circadian rhythms."

Childs says having the TV on affects REM sleep, the stage in which most dreams happen, and whatever you're watching can be 9intrusive into your dreams.

"That's when we have that 10restless kind of sleep that we go into, and we may be sleeping, 11quote unquote, but we're waking up and we're not rested."

But you can break this bedtime habit. Childs says to first practice good 12sleep hygiene. Avoid caffeine and alcohol before bed as well as afternoon naps. Try tea without caffeine to get you ready to turn in. Low lights can help or reading a book. Any bedtime 13ritual that helps prepare your mind and body for sleep. 

Childs says if you need background noise, try using a sleep mask to block the TV lights or put a timer on it to automatically turn off after an hour or two. You can also turn on a radio, listen to a podcast, or find 14soothing sleep music. There are also apps that can lead you in meditation before bed.

"You can train yourself to go to sleep without your TV."
