Circadian rhythm disorder is the result of the human body being out of balance.  This loss of balance is thought to be due to ignoring our body's impulses of when to sleep and desire for being out in nature.  Since we run our lives based on the need to achieve and ignore our need for sleep and activity, we can lose our natural balance that we would have if we lived outdoors and responded to our bodily needs.  This doesn't mean that to achieve circadian rhythm we need to live in the wilderness and give up our jobs, but rather that we need to be more aware of what our body needs.

Circadian rhythm disorder can cause depression because the imbalance we are experiencing is due to the imbalance created internally.  This means that the hormones, neurotransmitters, and other bodily chemicals are imbalanced.  Depression is also the result of an imbalance of these internal processes.  So that's why circadian rhythm disorder can cause depression.

Since circadian rhythm disorder is due to ignoring the bodily needs, researchers believe that by making changes in lifestyle, people can regain circadian rhythm balance, thereby removing the depression.  Lifestyle changes include spending more time in the sunlight, getting sufficient sleep, eating healthy, etc.  You will find that all psychologists make these lifestyle recommendations to people that are depressed.

Basically by ignoring what your body is trying to tell you, you lose balance and create depression.  This is why it is important to try and avoid circadian rhythm disorder and to treat it if you have it.  That way you aren't stuck in a depressed mode.
 
Although circadian rhythm disorder may sound "made up," it has been studied for at least two hundred years and is something that psychologists and counselors must consider when diagnosing someone with a mental health disorder.

Another treatment for circadian rhythm disorder that is research based is called light therapy.  This involves an increase in the patient's exposure to natural light, since the sunlight has been proven to create a more positive mood.  By spending more time by a window or enjoying the outdoors you can get the natural light your body needs to regain balance and alleviate depression.
