Changes can also be seen on people with bipolar disorder. For them, the spring and summer season can bring to them mania, rather hypomania, i.e. a less intense one. And for them, fall or winter can be a much depressed one.

Causes of SAD

There is no one particular reason behind the seasonal affected disease (SAD). Though any exact causes behind SAD is not yet understood properly, still there are some factors that can be taken under consideration

Circadian rhythm or body’s biological clock

Human body has its biological clock, which is associated with normal patterns of every day and night time. Any change in the biological clock can hamper individual’s lifestyle. During summer, people face long nights whereas on fall and winter people experience long nights and less sunlight. The decrease in the sunlight can in turn disrupt body’s biological clock, and hence leading them to have depression.

Production of serotonin

If the serotonin level drops, that will affect the mood. Serotonin is a type of hormone which is associated with a person’s mood. Reduction in sunlight can cause lower serotonin level, which in turn may affect mood, sleep and appetite. This can trigger depression.

Production of melatonin

Melatonin is associated with human’s sleep pattern. It is a hormone that can affect sleep. People with Seasonal Affective Disorder can produce higher melatonin levels than needed. And hence, it might make one feel more sleepy than usual.

There are risk factors involved in SAD. The disorder is seen more on women than on men. But no doubt, people irrespective of gender can be the victim of seasonal affective disorder (SAD). The risk factors increases if the person suffering from this has a family history i.e. have family members of same blood; or if that person is living far away from the equator, that person is likely to experience longer and shorter days and nights based on season and it will worsen if that person is suffering from bipolar disorder.

Treatment and Diagnosis

There are wide ranges of treatments for Seasonal Affective Disorder (SAD) available. It needs to be diagnosed if you notice that your depression is prolonged on that particular season and it is intensifying as the season is reaching its climax. There are various kinds of treatments done against this disorder. Such as:

The physician will have a thorough check on your day to day lifestyle. Measures will be taken on the exercise, management of stress levels and amount of natural sunlight you are getting.

Talking therapies like Cognitive Behavioural Therapy (CBT) and Counselling are needed to be done.

• Person suffering from Seasonal Affective Disorder (SAD) requires more sunlight than person not suffering from the same disease. Light therapy is used for the recovery. The patients might be exposed to a special kind of lamp, called a light box which stimulates exposure to the sunlight.

Antidepressant medications are also applied on the victims for a recovery.
