One of the more common and pronounced symptoms of people suffering from depression is erratic sleeping patterns. In its simplest terms, people manifesting this symptom either sleep too little or sleep too much. Irregular sleeping patterns can directly affect our mood and disposition, exacerbating any signs of depression. The human body is a complex machine.

Our different bodily systems, our psychology and physiology, interact with one another in such a way that the “cause” and “effect” of something might not be so clear-cut. An excellent example of this is the relationship between sleep and our physical and psychological health.
