seasonal-affective-disorderDo you experience depression pangs only during summer or winter? Do you find your mood to be fluctuating only during the winter and summer months?

It occurs almost at the same time every year. The symptoms of SAD appear for some time and then fade off. The incidence of SAD is quite common ranging from 1.4% in Florida to 9.7% in New Hampshire. Norman E. Rosenthal and his colleagues, who belonged to the National Institute of Mental Health, did the formal recognition and naming of SAD.

What causes SAD?

Want to know what exactly causes SAD? Well, interestingly the process of hibernation is the main reason that causes Seasonal Affective Disorder. Of course, we do not hibernate like the animals do… But the tendency to hibernate is present in every species in a dormant manner. It becomes active as and when required. Activity decreases during the winter months because of the scarcity of food and the extreme weather conditions. Though you may find food to it during all the seasons, yet the environmental conditions may make you feel low and sloppy. Changes in the environmental conditions have a great influence on human body and behavior. It is often considered that SAD is the residual symptom of some remote ancestor who had a tendency of hibernation response.

Apart from this the presence of the amount of light and clouds in the atmosphere and environment also play a vital role in the development of SAD. It is more common in the Arctic region, Northern Finland etc. Lack of exposure to proper light influences the brain and body chemicals. If you are not exposed to proper light conditions then your circadian rhythm may also suffer, resulting in SAD.

Incidence Rate of SAD

Region Incidence
Arctic Region (e.g. Northern Finland) 9.5%
US Population 14.3%
Florida 1.4%

In a nutshell, light and weather conditions play a vital role in the incidence of SAD. Therefore, the treatment interventions of SAD are also based on this aspect.
