I can attest to this issue first hand. In 1995 I was diagnosed with cancer and had to undergo major surgery, recovery from that in ICU, then several rounds of chemotherapy over the next nine months. While I was in the hospital for a week of chemo, I got maybe two or three hours of sleep per night with a half hour nap off and on throughout the day, and this was on sedatives and painkillers. I can only imagine how much better my recovery would have gone if I'd been allowed to sleep all night during my stays and didn't need sedatives to balance the constant interruptions. I'm certainly not a medical expert nor a sleep expert, but I'd wager if nurses and doctors would let their patients have a full night of rest without interruption, they would see much faster recovery times.
