S.A.D. or Seasonal Affective Disorder is a type of depression that occurs during the colder months of the year, and it may be caused from a lack of uninhibited sunlight.
This fact can be proven from other studies that suggest there are far fewer cases of S.A.D. in southern states, when compared to northern states.
What are the symptoms of S.A.D.? According to the Mayo Clinic, winter-onset seasonal affective disorder symptoms may include:
§ Feeling depressed or moody much of the time
§ Feelings of hopelessness
§ No energy - feeling tired all the time
§ Appetite changes & weight gain
§ Loss of interest in activities
§ Difficulty concentrating and more.
