Not getting enough sleep? If you live in West Virginia, there's a good chance that you're part of the 20% of the population who suffer from insomnia:
West Virginians' lack of sleep was about double the national rate, perhaps a side effect of health problems such as obesity, experts said.
Nearly 1 in 5 West Virginians said they did not get a single good night's sleep in the previous month. The national average was about 1 in 10, according to a federal health survey conducted last year and released Thursday.
Tennessee, Kentucky and Oklahoma also were notably above average in their reported lack of sleep. In contrast, North Dakota had fewer problems sleeping, with only 1 in 13 reporting that degree of sleeplessness.
Health officials do not know the exact reasons for the differences.
