A sleep disorder, or somnipathy, is a medical disorder of the sleep patterns of a person or animal. Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Polysomnography and actigraphy are tests commonly ordered for some sleep disorders. (Wikipedia)

Most published data on sleep disorders in prisoners stem from investigations conducted by Elger (2003, 2004, 2009), with male prisoners suffering from insomnia in a Swiss remand prison (similar to U.S. jail). (US National Library of Medicine)
