Sleep-wake disturbances are actual or perceived changes in night sleep with resulting daytime impairment. There are a number of demographic-, lifestyle-, environment-, disease-, and treatment-related factors that can increase the risk of sleeping problems in patients with cancer, including symptoms such as pain, nausea, anxiety, depression, and hot flashes. Sleep-wake disturbances have been reported in 30%–75% of people with cancer.
