Excessive Sleep as Symptom

Illness reduces the body's cellular energy production, causing the body to prioritize repair and increasing the drive to sleep more. Depression and anxiety are independently associated with increased sleep duration and may explain higher sleep in affected individuals. Undiagnosed sleep apnea can cause excessive sleep and also independently elevates stroke risk through a separate pathway that the study did not control for. Regularly sleeping more than nine hours or taking very long naps is a symptom worth investigating rather than the problem requiring intervention. The appropriate response to excessive sleep is to investigate and address the root cause rather than artificially curtailing sleep.
