Depression is an integral aspect of sleep disturbance (either sleeping less or sleeping more), according to a journal published on the National Library of Medicine National Institutes of Health. Though the direct link of both issues may be still debatable, but more scientific evidences continue and move on to mount that the sleep disturbance (including for sleepy feeling) and depression are intertwined.
Feeling sad or angry for once in a while in your life is completely normal, because we all agree that this is a fundamental part of the journey in live (naturally human experience).
But persistent feeling of anxiety, hopelessness, disinterest, and sadness should be concerned as well because they are some common symptoms of depression!
Unfortunately, many people still ignore and underestimate the presence of this mood disorder. In fact, it affects about 20 million people in the U.S. Most doctors agree that it is a serious health condition. If left untreated, it can be potential to affect the way of patient to think, eat, feel, and sleep.
The sleep disturbance itself in depressed people can generate a cascade of other problems. It can affect the productivity of patient, and even sometime it also can contribute to cause some physical symptoms of depression (such as headaches, weight changes, and easier to have fatigue).
Though sometimes doctors cannot provide the answer of this question with certainty, generally most experts agree that depression can make you sleepy. But not all depressed people experience this symptom.
While some depressed patients may feel sleepy (sleeping too much a day), the opposite occurs in other patients (sleeping less or experiencing insomnia). Even sometime a depressed person may also have alternating excessive sleeping and sleeping too little.
It’s not clear which one that comes first. This is like egg and chicken. While some patients report that they experience depression first then followed with sleep disturbance, others find that they have sleep disturbance first then depression. But one thing that has been confirmed that this mood disorder often co-exists with sleep disturbance – and vice versa!
The connection between both conditions is pretty complex. Both may share biological features and risk factors, and even both may respond to the same strategies of treatment. Additionally, sometime severe depression is closely related to sleep problems.
One of common sleep disturbances in depressed people is insomnia. Some studies found that people with insomnia have higher risk of developing depression than others who can sleep well. On the other hand, depressed people are also more likely to experience a range of insomnia problems (such as daytime sleepiness, trouble staying asleep, and trouble falling asleep). People with both difficulty staying asleep and difficulty falling asleep may be at highest risk of having depression.
Another type of sleep disturbance that is pretty common linked with depression is OSA or ‘Obstructive Sleep Apnea’. According to a research from the Stanford researcher Maurice Ohayon, depressed people may be 5 times more likely to develop OSA and other types of sleep-disordered breathing. The good news, depression that co-exists with OSA can be treated successfully with CPAP method (continuous positive airway pressure method).
Furthermore, there is a chance for the depression symptoms to overlap with sleep disorder symptoms, and this is one of major reasons for many misdiagnosis of this mood disorder. For instance, depressed mood also can point to the presence of narcolepsy, obstructive sleep apnea, or insomnia.
