"As we start to move into our 60s, 70s, you have more issues with the depth of your sleep, so your sleep is just lighter in general," Harris told CBS News. "There's sleep disorders, like insomnia, that happens, and then you have to go to the bathroom more at night."

"The deepest stage of sleep is where your muscles are repairing, you're growing — and as you're getting older, you don't need that ideally as much as you do when you're younger," Harris said, adding that younger kids get a lot of deep sleep.

"(Older adults) just wake up a lot more because of pain and movement and having to urinate," she added."
