A new study by researchers at the University of Pennsylvania has found people from the southern states to be the sleepiest of all in the United States.

“Sleep disturbance is a major public health concern. However, geographic dispersion of sleep problems, and the factors that may play a role in why some states or regions get better sleep, have been largely unexplored”, lead researcher Michael Grandner said. The study has been published in the Journal of Clinical Sleep Medicine.
