The homeless sleep less and are more likely to have insomnia and daytime fatigue than people in the general population, according to a research letter published online by JAMA Internal Medicine. Researchers believe the findings suggest more attention needs to be paid to improving sleep for this vulnerable population.

Sleep is part of good health, but the homeless often have no access to safe and warm beds at night. Damien Léger, MD, PhD, of the Université Paris Descartes and Assistance Publique Hôpitaux de Paris, France, and coauthors analyzed responses from 3,453 people who met the definition of homeless in French cities; most of the participants were men and had an average age of almost 40. They were living on the street, in short-term shelters, small social services paid hotels and other facilities for homeless people with children.

A questionnaire was used to ask about total sleep time at night and over the past 24 hours. Responses from the homeless were compared to individuals in the general population who participated in a large survey of the French adult population.

The homeless reported shorter total sleep (6 hours 31 minutes vs. 7 hours 9 minutes). Among the homeless, 8 percent reported less than four hours of total sleep over the past 24 hours compared with 3 percent of the general population, according to the results.

Homeless women also were twice as likely as men to report that they slept less than four hours and insomnia was reported by 41 percent of the homeless compared with 19 percent of the comparison group. Also, 33 percent of the homeless reported daytime fatigue compared with 15 percent of the general population. Among the homeless, 25 percent also reported regularly taking a drug to help them sleep compared with 15 percent of the control group, the results suggest.

“We believe that improving sleep deserves more attention in this vulnerable group. We strongly support strategies other than hypnotic agents to improve sleep in the homeless, including more careful control of noise, lighting, heating and air conditioning at night. Facilities could provide residents with sleep aids, such as earplugs, eye sleep masks and pillows. Screens between beds could offer some sense of privacy, even in collective dormitories, and addressing issues of personal security should promote better sleep,” the article concludes.
