Sleep plays an important role in emotional and physical well-being, but research shows it may also help determine who gets cancer and how successfully they recover. In a study that looked at 1,200 women diagnosed with breast tumors between 2005 and 2008, rates were 30 percent higher in those who worked shifts versus regular schedules, and researchers found similar results in men with prostate tumors.
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.
