What we have found from recent research is actually insomnia may cause depression rather than depression causing insomnia. Actually either can cause the other. When you are depressed one of the things you do at times is sleep. You might sleep during the day at which point you may not feel sleepy at night. Another reason you do not sleep is you do nothing. You have no physical activities so while your brain gets tired your body does not so you have trouble falling asleep.
In what ways may insomnia cause depression?
Insomnia can arise from medication, worry, lack of activity, physical problems of the brain and other reasons as well. If you are without sleep you will become depressed. Any person who has tried to work on a problem while they are tired knows that if they stop and get some rest, the problem will not seem so great the next morning.
Insomnia and depression are truly a vicious circle and can become even more complicated. Lack of sleep causes problems and problems create lack of sleep. Besides medicine and worry insomnia can even be caused by genetics.
How can insomnia or depression be treated?
After identifying what the situation is, whether the person is an insomniac, or in a depressive state, the doctor can decide if they need medication or counseling or both. He also may suggest diet and exercise changes. The most important thing to find out is whether there is a physical problem needing to be taken care of. Most people are not interested in finding that out but it is often a root cause. Rarely is there something in a person’s makeup that stands alone. There is usually some cause or some connection of another part of the person’s body or thinking that is causing the problem. It is a matter of finding the base cause.
In women depression may come on after delivery of a child. This is called Post-partum depression.
I have had the cycle of depression and insomnia. In my case insomnia is caused by mania. I am a manic depressive and when I am in a manic depressive state my mind does not shut down. It is constantly thinking. I may go to bed at 11 pm. but will not go to sleep until 5 am. Of course the next day I am exhausted.
This ultimately brings on depression and then between the two conditions I cannot get things done which causes worry which causes more insomnia and depression. It is a vicious cycle.
That is why it is important to see a doctor; they know the best intervention at wherever you are in your cycle.
