Seasonal affective disorder (SAD) is a form of depression most often associated with the lack of daylight. Although seasonal affective disorder is most common when light is low, it may occur in the spring, and it is then often called reverse SAD.
no more often than any other people.
Studies have shown that some people suffer from Seasonal Affective Disorder, or seasonal depression, often brought on by shortening of the daylight hours. The less light, the higher the risk of feeling depressed, which can affect your daily work ability.
Seasonal Affective Disorder (SAD) in the mildest form is often referred to as the "winter blues" but more severe SAD can lead to depression. Symptoms are similar to other forms of depression, which is why it is important to get diagnosed by a Doctor to ensure you get the right treatment. This may involve taking Anti-Depressants but before you resort to drugs, there's various self help methods that can help. I use a Light Box to bathe me in the equivalent of natural light and sunlight during the winter months. Clinical studies have shown that this helps a large number of people who suffer from SAD.
SAD or Seasonal Affective Disorder, is often treated with light therapy or a light box to help improve the overall well-being of the individual. SAD often occurs during the winter months when there is less natural daylight so the use of artificial sunlight can help improve the mood and relieve depression.
As the winter months set in across the Northern Hemisphere, thousands of people must deal with a subset of depression known as Seasonal Affective Disorder. This disorder is often referred to by its all-too-appropriate acronym. SAD sufferers may feel listless, depressed or unusually emotional throughout the winter months. Scientists believe that the season's short hours of sunlight and long, cold nights can create subtle malfunctions in the biological clocks of people who suffer from SAD.What Causes Seasonal Affective Disorder?The so-called "biological clock" refers to the complex interplay of hormones in the body and brain that tells humans when to wake up and when to sleep. Usually, these hormones are attuned to the presence of natural light; humans rise in the morning when the sun is up and fall asleep after dark. Disturbances like jetlag or insomnia can occur when these bodily cues no longer match up with the rising and setting of the sun. In the winter, shorter days make people want to sleep more. Some people cannot adjust to this lack of natural light without becoming cranky and irritable; their bodies tell them that they need to sleep, but their work schedules do not accommodate long mornings spent dozing in bed. In some people, these hormonal fluctuations are severe enough to cause lethargy and depression.Can Seasonal Affective Disorder be Cured?While there is no easy cure for SAD, there are treatments that can reduce or prevent listlessness and depression during the winter. Many companies produce lamps for depression caused by Seasonal Affective Disorder. These lamps are compatible with bright light bulbs that can produce "full spectrum" light. This means that the light that is generated by these bulbs can effectively mimic the full range of visible light produced by the sun. Full spectrum lights can trick a SAD sufferer's brain into producing the proper chemicals required for a functional biological clock.These lights are most effective in the morning. Because many SAD sufferers have to rise before the sun, these bright lamps can mimic the feeling of natural sunlight in the morning. Some people who are vulnerable to Seasonal Affective Disorder choose to supplement this light therapy with oral doses of Vitamin D. This combination of full spectrum light and Vitamin D can reduce or eliminate moodiness and depression in the winter months.
An Ott light is a proprietary fluorescent bulb and/or lamp which produces something approaching a natural daylight spectrum. (See http://www.ott-lite.com/Cms/home.aspx.) Professional photographers often use them as a daylight standard for proofing their prints. It is also said to have some health benefits (reducing eyestrain, seasonal affective disorder, etc.).

The presentation of depression is often affected by environmental factors including miserable weather, or discomfort. This is common with normal depression, though some people who are severely affected by the amount of natural light may be diagnosed with SAD (seasonal affective disorder). Be aware however that just because you feel miserable on a gloomy day does not mean you have SAD. Natural sunlight stimulates the release of serotonin in the brain, a hormone that makes you happy.
Mood disorders, also called affective disorders, are a group of illnesses that have as their distinguishing characteristic an experience of mood that is unusual for the circumstances. Common mood disorders include bipolar disorder, depression, postpartum depression, cyclothymia, schizoaffective disorder, and seasonal affective disorder. Most mood disorders are at least somewhat treatable with drugs and psychotherapy.
