What is bipolar insomnia? How are bipolar disorder and insomnia connected?
Sleep disturbance is a significant feature of bipolar disorder, and is one of several criterion used for diagnosis, as it is a frequent symptom of both mania and depression.
During manic episodes it’s common to feel a decreased need for sleep, or suffer from insomnia.
But bipolar disorder and insomnia, and the associated sleep loss isn’t just a symptom of mania; reduced sleep can also trigger manic episodes and is a good predictor of the onset of mania.
The depressed phase of bipolar is characterized by hypersomnia, where a person sleeps for extended periods or naps frequently throughout the day. This irregularity in sleeping patterns then tends to increase the risk of new episodes of mania or depression.
Interestingly, research has found that disrupted sleep patterns are
common in people with bipolar disorder even between bipolar episodes.
For reasons not yet understood, people with bipolar disorder have more
delicate body clocks.
The treatment of sleep disturbances and
maintaining a regular sleep/wake cycle are important components in the
prevention of mood episodes in bipolar disorder.
Circadian rhythms, bipolar and sleep
A circadian rhythm is approximately a 24-hour cycle in our biochemical, physiological and behavioral processes.
Not sleeping but still feel energized? This is a classic sign of bipolar mania.
Our circadian rhythms govern sleep, hormonal function, appetite and body temperature.
Scientific research suggests that the Clock gene, which regulates the
body’s circadian rhythms, may be involved in the development of bipolar
People with bipolar disorder generally have
irregularities in their circadian functions, including the body clock
and its sleep/wake cycle.
Exhaustion, sleeplessness and disruptions to sleep patterns can trigger a bipolar episode.
Establishing and maintaining a regular sleep/wake schedule, as well as stabilizing the circadian rhythm, are the primary elements of a relatively new treatment for bipolar disorder.
Some scientists believe that the increase of bipolar disorder in modern times is caused by the widespread use of artificial light. Before artificial light people’s sleep/wake cycles were regulated by the sun; it is possible that people who are genetically predisposed to bipolar disorder may develop the condition without the overall patterns of dark and light changing slowly and naturally.
Regular sleep helps bipolar
Sleep is an essential part of good health in all people and is vital to our well-being. Insufficient sleep causes significant health problems such as increased stress on the immune system, anxiety, depression and increased risk for gastrointestinal and cardiovascular disease.
Deep restful sleep is of particular importance to manic depressives, as bipolar disorder can impair judgment and lack of sleep can exacerbate this.1
Daytime mood regulation and night-time sleep form a two-way relationship; once rhythms are disturbed such as with bipolar insomnia, a self-perpetuating cycle can begin where moods interfere with sleep and then disrupted sleep affects mood regulation the following day.
It is recommended that people suffering from bipolar insomnia and hypersomnia go to bed at the same time each night, and get up at the same time each morning.
Regular schedules and sleep patterns have a positive affect on
bipolar treatment and it is advised that activities that disturb normal
routines be avoided. Re-establishing and maintaining a regular sleep, meal and activity schedule is one of the reasons why a stay in a bipolar treatment center can be such so helpful.
