Early Sunday morning, clocks were set back one hour for daylight-saving time, leaving some people feeling extra tired. “Springing forward” not only causes people to lose one hour of sleep, but also disrupts their sleep cycles.

The recommended sleep duration for people between the ages of 18 and 26 is at least seven hours each night, according to the Centers for Disease Control and Prevention (CDC).

Sleeping less than that can have serious consequences, including an increased risk of health problems like obesity, diabetes and high blood pressure; and an increased likelihood of motor vehicle and industrial accidents.

Using 2014 Behavioral Risk Factor Surveillance System data, the CDC determined the prevalence of a healthy sleep duration among United States adults and found that 7,707 of Connecticut respondents — or 64.8% of the state’s adult population — reported getting seven or more hours of sleep each night.

The Behavioral Risk Factor Surveillance System is a state-based, random-digit–dialed telephone survey of the noninstitutionalized U.S. adult population, conducted collaboratively by state health departments and the CDC.

For the 2014 survey, people were asked how many hours of sleep they get in a 24-hour period on average. Among 444,306 respondents, approximately 65% reported a healthy sleep duration of seven hours or more. The results broke down as follows:


  • 11.8% reported five or less hours.

  • 23% reported six hours.

  • 29.5% reported seven hours.

  • 27.7% reported eight hours.

  • 4.4% reported nine hours.

  • 3.6% reported 10 or more hours.


State-based estimates of healthy sleep duration prevalence ranged from 56.1% in Hawaii to 71.6% in South Dakota, with people in the southeastern United States and along the Appalachian Mountains having the lowest prevalence of healthy sleep duration and those in the Great Plain states having the highest observed prevalence.
