Seasonal depression, often called seasonal affective disorder (SAD), is a depression that occurs each year at the same time, usually starting in fall or winter and ending in spring or early summer. It is more than just "the winter blues" or "cabin fever." A rare form of SAD known as "summer depression," begins in late spring or early summer and ends in fall.
What is light therapy, and is it safe?
Light therapy, sometimes called phototherapy, is administered by a device that contains white fluorescent light tubes covered with a plastic screen to block ultraviolet rays. The intensity of light emitted (Lux) should be at least 10,000 Lux. The patient does not need to look directly into the light, but reads or eats while sitting in front of the device at a distance of 2 to 3 feet. Light therapy is safe and generally well tolerated.
Minor side effects of light therapy include:
•Eye strain
•Headache
•Irritability
•Fatigue
•Insomnia
At what time of the day and for how long should I use light therapy?
Recent studies suggest that morning light therapy is more effective than evening treatments. Using this treatment too late in the day may also produce insomnia. Many health professionals today prefer to treat SAD with 10,000 Lux for 30 minutes every morning. Patients have shown some improvement within 2 to 4 days and reach full benefits within 2 to 4 weeks. The symptoms of SAD return quickly after discontinuation of light therapy, so light treatment should be continued throughout the entire season of low sunlight.
Even though they generate enough light, tanning beds should not be used to treat SAD. The amount of ultraviolet (UV) rays they produce is harmful to the skin and eyes.

Web definitions for depression: a mental state characterized by a pessimistic sense of inadequacy and a despondent lack of activity.
Theories About Causes
Medical research has contributed much to our understanding of depression. However, scientists do not know the exact mechanism that triggers depressive illness. Probably no single cause gives rise to the illness, and researchers continue to piece the puzzle together.
In the past, doctors believed that depression was the result of thoughts or emotions that were troubling for a person. More recently, experts realize that there can be several factors working together that will lead a person to become depressed. The three most important of these are biological, genetic, and environmental factors.
Biological causes are due to changes in the chemistry of the brain, such as fluctuations in the levels of important hormones. Genetic causes are the result of what you inherit from your parents. If one or both of your parents have a vulnerability to depression, then it can be transmitted to you. Environmental factors (also called emotional factors) result from stressful emotional situations, such as a lack of loving parents or the death of a parent during childhood. To make it even more complicated, depression can also occur as a result of a combination of the three factors just mentioned. If you inherited a vulnerability to depression from one of your parents, your brain may react to a stressful event in a way that causes you to get depressed.
Depression can also develop due to a physical illness, a reaction to a medication that you are taking, or as an outcome of substance abuse. In these cases, when the cause is successfully treated, the depression will end.
Genetic Factors
Scientists believe genetic factors play a role in some depressions. Researchers are hopeful, for instance, that they are closing in on genetic markers for susceptibility to manic-depressive disorder.
Recent genetic research also supports earlier studies reporting family links in depression. For example, if one identical twin suffers from depression or manic-depressive disorder, the other twin has a 70 percent chance of also having the illness. Other studies that looked at the rate of depression among adopted children supported this finding. Depressive illnesses among adoptive family members had little effect on a child's risk of depression; however, the disorder was three times more common among adopted children whose biological relatives suffered depression.

I tend to disagree with the statement that people who can get themselves out of their depression are 'situational' and those who can't are 'clinical'.
Situational Depression
• an episode of emotional and psychological depression that occurs in response to a specific set of circumstances.
Clinical Depression
• depression that is serious enough to require psychiatric intervention and treatment.
• a state of sadness or melancholia that has advanced to the point of being disruptive to an individual's social functioning and/or activities of daily living (ADLs).

Yes and you are perfectly correct..........exercise helps but only so much. There is a hard wiring, a set medical condition that is very real for many people.
I was trying to be helpful and apologize if it came across as something else.

I have clinical depression. Without the aid of medication, my typical day consists of a strong build-up of anxiety throughout the day until it erupts into a full blown panic attack. I suffer from racing thoughts of hopelessness and helplessness. I feel trapped inside my own body and my own mind. I see my world as a prison which I cannot escape. When I am in this state of mind, I see no way out; I see no end; I feel locked in my suffering for the remainder of my life.
