Doctors are trying out new ways to give sick children better shut-eye, reports The Atlantic.

Between the fluorescent lights, the chatter of on-duty doctors and nurses, and being roused for things like baths and vitals checks, getting eight hours of shut-eye is challenging. So now, with research increasingly highlighting the link between sleep and good health, children’s hospitals are rethinking just how they work at night.

“If we’re going to try to heal kids, we need to try to have them do the one thing that’s so important for their brain development. And that’s optimizing their sleep,” said Sapna Kudchadkar, an assistant professor of anesthesiology, critical care and pediatrics at Johns Hopkins Children’s Center in Baltimore. She launched an initiative to improve sleep in the hospital’s pediatric intensive care unit a year ago.
