Does depression cause insomnia or does insomnia cause depressive symptoms? Although you might think that insomnia is a symptom of depression, unfortunately, insomnia can also be a cause of depression. The two therefore strongly reinforce each other.
People need an average of 7 to 9 hours of sleep per night, but people with depressive symptoms may sleep very little for long periods. Excessive worrying or thinking in bed can contribute to this sleep deprivation, which then prolongs the recovery period and reduces concentration. Conversely, sleep problems, such as too little sleep, can also lead to depressive symptoms.
Too much or too little sleep: Both can play a role
In addition to too little sleep, people with depression may also tend to oversleep. This occurs more often when people lack motivation to get out of bed, feel listless or tired, or experience one of the other symptoms of depression. However, it is important to note that sleeping too long or too much can ultimately worsen depression. Although people often think that sleeping a lot when they are tired helps, it often has the opposite effect and can intensify feelings of gloom.
Sleep apnea: An underlying cause of sleep deprivation and depression
Sleep apnea is a condition where breathing stops or pauses during sleep. This can lead to a disturbed sleep pattern and cause daytime sleepiness. Due to this extreme fatigue, someone can develop depressive symptoms. One in three people with sleep apnea experiences depression or burnout. Treating sleep apnea can therefore not only improve sleep quality but also reduce depressive symptoms.
