S.A.D. or Seasonal Affective Disorder, is depression that occurs in a seasonal pattern, most commonly in the winter months, and sometimes it is called “winter depression” (1).
Additional symptoms may include fatigue, weight gain, increased appetite, oversleeping (1) occurring in a seasonal pattern.
SAD may often co-occur with a variety of other mental health conditions.
It can often occur as part of other mood disorders such as depressive disorders, bipolar disorder, etc (2).
What are some Treatment options for S.A.D.? (3)
- Vitamin D (5)
- Light therapy
- Other helpful strategies for improving depression may include : nutrition (6 ), exercise (7 ), and being socially active.
A recent study looked at the impact of light therapy on sleep and circadian rhythm.
What was the study?
The study authors (8) identified and reviewed 40 available studies on the subject.
What were the results?
- The study authors (8) found that while both bright light and SSRi’s helped mood, bright light therapy also helped with sleep wake cycle.
- Separately (9), an analysis of 3 randomized trials found that dawn simulation ( a type of light therapy delivered in the mornings) helped with mood and reduced difficulty awakening and reduced morning drowsiness (9).
What are some caveats?
While the treatments are beneficial:
- Light therapy can have side effects (10) such as mania, hyperactivity, irritability, headaches, etc.
- Other treatment options mentioned above can also have side effects.
For this reason, if you are experiencing a seasonal pattern of depression, please seek the help of a mental health professional to determine IF and how much and what type of treatment may be best for you.
