(NewsUSA)- As the gray days of winter continue to mount, it may seem natural for your mood to match the weather.
But if these feelings last for an extended period, or return year after year, you could be suffering from Seasonal Affective Disorder (SAD).
SAD is a type of depression believed to be related to the varying amount of daylight that occurs throughout the seasons. The most common type is winter depression. People typically experience symptoms as winter approaches and daylight hours become shorter. When spring returns, they experience relief from these symptoms and a return to normal mood and energy levels.
In fact, approximately 6 percent of people experience severe SAD, and another 10 to 20 percent may suffer from a mild version. Like other forms of depression, females are about four times more likely than males to develop SAD, as are people with relatives who have experienced depression.
Symptoms of SAD may include:
Changes in mood. Feelings of sadness, irritability and a sense of hopelessness or worthlessness for at least two weeks. Tendencies to be more self-critical and more sensitive than usual to criticism are also signs.
Lack of enjoyment. Loss of interest in things that are normally enjoyable, feeling like tasks can't be accomplished as well as before and feelings of dissatisfaction or guilt can be an indication of SAD.
Low energy. Unusual tiredness or unexplained fatigue can be a result of this illness.
Changes in sleep. Sleeping much more than usual is tied to the lower energy levels experienced by individuals suffering from SAD.
Changes in eating. SAD may also cause a tendency to overeat, especially when it comes to comfort foods and sweets, and can result in weight gain during the winter months.
Difficulty concentrating. If you are having more trouble than usual completing assignments on time or have a lack of motivation, SAD could be the culprit.
Less time socializing. Spending less time with friends at social or extracurricular activities is a symptom of this depression.
If a person experiences these symptoms, it is important to discuss it with a personal or family physician. There are a number of highly effective treatment options that can help relieve SAD sufferers of their winter woes.
