Passaro reports morbidity and mortality consequences of chronic insomia in his article “Insomia”:
– Patients with insomnia report decreased quality of life compared with normal controls.
– Patients with insomnia report excessive fatigue as measured by the Fatigue Severity Scale and the Profiles of Mood Status.
– Patients with insomnia are more than twice as likely as the general population to have a fatigue-related motor vehicle accident.
– Increased occupational dysfunction and decreased work performance are likely due to chronic hyperarousal state or perceptions of sleep deprivation rather than actual sleep loss from insomnia. For example, unlike patients with chronic sleep deprivation from other causes, patients with insomnia report less excessive daytime sleepiness and less psychomotor and cognitive impairment.
– Knutson et al found that the quantity and quality of sleep correlate with future blood pressure. In an ancillary to the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study, measurement of sleep for 3 consecutive days in 578 subjects showed that shorter sleep duration and lower sleep maintenance predicted both significantly higher blood pressure levels and adverse changes in blood pressure over the next 5 years.
