Seasonal Depression Disorder is also commonly referred to as SAD, [Seasonal Affective Disorder] is a type of depression. This form of depression takes place at the same time every year and starts in the fall. This condition can last throughout the entire winter months but thankfully ends in the spring or summer months. There are good reasons why these months are more prevailing for this depression disorder.
The main reason is the much shorter days, with extra hours of darkness, combined with the colder weather, which generally means for a lot of people staying indoors more oftentimes can promote this type of depression. The shortened hours of natural sunlight is also another ingredient in seasonal depression disorder.
The normal treatment is usually antidepressant medicine and therapies, like light therapy which is very effective. This is a condition that will require diagnosing and treatment in some form so you can live a normal during the long winter months when this seasonal depression strikes.
Quite a bit of research has been done to discover the cause of it and why it occurs at the same time every year and, although there is no convincing data, there are a few factors that are thought to bring about this type of depression. These factors are the biological clock, along with the level serotonin and melatonin in the body during these times of the year.
The biological clock, medically referred to as the circadian rhythm can be affected by symptoms of seasonal depression especially in the fall and winter months bring increased symptoms of winter depression because of the longer hours of darkness. This interrupts the circadian rhythm and this can bring on the feelings of depression when connected with the other factors. Serotonin has a vital role in the brain as a neurotransmitter, which can affect the mood you're in. The reduced quantity of sunlight could be causing a decreased quantity of serotonin in your body. Melatonin is another chemical in the brain that assists in balancing the hormones, affecting sleep patterns and mood.
There are a few groups of people who are at more risk for this seasonal type of depression. Women are more frequently diagnosed with seasonal depression disorder, than men are. Women who are affected by the yearly seasonal depression have more severe symptoms than men who are affected.
The precise cause of this condition isn't well-known, but the effect of latitude on seasonal depression disorder strongly indicates that it is induced by changes in the amount of sunlight. One hypothesis is that with lessened exposure to sunlight, the biological clock that determines mood, sleep, and hormones is thrown out of whack, running a lot slower in the winter. Exposure to light could readjust the biological clock.
