Where you live may affect how you sleep, according to researchers from the Perelman School of Medicine at the University of Pennsylvania. People living in Southern states suffer from more sleep disturbances and daytime fatigue than other regions, while residents on the West Coast report the fewest number of problems, the research team reported in a study published online in the Journal of Clinical Sleep Medicine. Looking at nationwide data collected in 36 states by the Centers for Disease Control and Prevention (CDC), the researchers developed a state-by-state sleep map. Among the states where data was collected, Oklahoma, Arkansas, Mississippi, Alabama and West Virginia ranked in the highest bracket for each category. Many of the states reporting the worst sleep and fatigue problems are the same states that tend to report higher prevalence of other conditions, such as obesity. The pattern differed slightly between men and women.
Some of the factors that may play a role in sleep disturbances include demographics, obesity, health and even weather and sunlight patterns in different states. They found that regional differences in mental health, race and ethnic origin and access to medical care were the streongest factors that explain these regional differences. The Penn research team suggests that for regions with the worst sleep patterns, public health programs focused on healthy sleep patterns and increased screening programs for sleeplessness symptoms may guide those suffering from sleeplessness to receive the appropriate medical care.
