With subjects coming from Delaware, Hawaii, New York and Rhode Island, 13.3 percent of people between ages 18 and 34 reported that they were not getting the appropriate amounts of sleep. The figure showed higher than the 7.3 percent for adults over the age of 55.
"It's important to better understand how sleep impacts people's overall health and the need to take steps to improve the sufficiency of their sleep," UPI quoted lead author Lela R. McKnight-Eily.
Other findings from the study revealed, however, that the proper amount of sleep, which is about 7-9 hours for adults, is obtained by people upon retirement.
Details from the study confirmed that an entire month of adequate sleep was most likely had by those who have stopped working, and are living out their days in relaxation. ABC News reported that the same was true for those whose mental or physical conditions make them unable to work,
The researchers concluded sleep deprivation is also caused by lifestyle habits, such as late-night television, Internet use, ingestion of caffeine or other stimulants, and even the type of job one has.
The results of the study did not show any difference upon consideration of race and gender.
