A new study in Australia reviewed how the noise levels in hospitals throughout the country impacted patient recovery time and sleep, the Canberra Times reports.

The nation’s first hospital-wide review of patients’ sleeping habits found only one-quarter reported a good quality snooze, which the report author warned meant slower recovery times and longer stays.

Researcher Lori Delaney said the six-month study, set to bring about a range of changed practices, found overnight patients slept for an average of 5.3 hours at the capital’s largest hospital, 1.8 hours less than at home.
