Hoarders tend to not sleep well at night, according to a recent study.

Researchers found that those at risk of hoarding disorder often complain about their sleep. Their findings show that this group scored significantly higher on a survey that asked about sleep latency; sleep disturbances and daytime disturbances among other things.

Hoarding, what people at risk of developing a hoarder disorder do, is a term used to describe a behavior that leads people to accumulate food or other items during periods of scarcity. These people acquire an excessive amount of objects and are unable or unwilling to discard large quantities said objects that cover the living areas of the home and cause significant distress or impairment.

"Hoarders typically have problems with decision making and executive function; poor sleep is known to compromise cognition generally, so if hoarders have cluttered/unusable bedrooms (and less comfortable, functional beds), any existing risk for cognitive dysfunction, depression and stress may increase as sleep quality worsens," Pamela Thacher, lead author of the study and an assistant professor of psychology at St. Lawrence University in Canton, N.Y., said in a statement.

For the study, researchers collected data from a sample of respondents from Amazon's Mechanical Turk website. Their advertisement asked for those interested in hoarding, sleep, or clutter, whether or not they had problems with these areas. Questionnaires included: Demographics; PSQI; Clutter and Hoarding Rating Scale (CHRS) and SH.

The findings are detailed in the journal Sleep.
