Both, in cases of mania and depression in bipolar disorder, sleep disorders are common. In depressive episodes a person with bipolar disorder is more prone to hypersomnia (excessive sleeping) as well as non-restorative sleep. In a manic phase, the person commonly feels less need for sleep (insomnia), sometimes staying up 20 hours at a time, or more.1

The Link Between Bipolar Disorder and Sleep

In-depth info on bipolar and sleep problems, like insomnia. Why many with bipolar disorder have a sleep disorder. How to improve bipolar disorder sleep.The human body has a built-in clock telling every cell in the body what time of day it is; this is known as the circadian clock or rhythm. This internal rhythm synchs to external cues such as the rising and setting of the sun and mealtimes, and directly affects when the body sleeps. While anyone can experience insomnia or another sleep disturbance when their circadian rhythm is disrupted, those with bipolar disorder seem to be particularly sensitive. Something as simple as staying up late to attend a party may disrupt the circadian rhythm enough to provoke insomnia.

Insomnia Can Predict or Cause Bipolar Depression or Mania

While a night of insomnia is normally considered simply a hassle, for a person with bipolar disorder it may signal an oncoming depression or manic episode. Studies have found that between 25 and 65 percent of bipolar patients experienced an interruption in circadian rhythm just prior to a manic episode. To make matters worse, a perceived lack of need for sleep is common in manic episodes. Once the mania begins, a person is likely to further deprive themselves of sleep, making the mania worse.
