While doing research on this topic I stumbled upon many different reasons as to why my topic could be proven factual.

I chose to accept this topic because rarely so I hear anything about SAD let alone someone talking about it. WHAT IS SAD?

Seasonal affective disorder has not been long recognized as an official diagnosis. The term first appeared in print in 1985. Seasonal affective disorder is also sometimes called winter depression, winter blues, or the hibernation...
