Seasonal Affective Disorder (SAD) affects more than 10 million people in the United States.
So as we ease into the beginning of Winter, it is important to understand what it is so we can take care of ourselves or support someone we care about.

What causes SAD?
Although scientists continue to research this, studies show it might be caused by one or more of the following things:
- Lack of sunlight
- Imbalance of a chemical or hormone in the brain
- Lower levels of Vitamin D
- Use of Melatonin or Overproduction of Melatonin
- Poor sleep patterns caused by changes in your circadian rhythm (biological clock) often caused by shorter daylight hours
- Low Serotonin levels
- Negative thoughts or feelings associated with a specific season
- Hot Temperatures when there are longer daylight hours (specifically for Summer Depression)

- Light Therapy or Phototherapy – exposure to special lights which can mimic outdoor light resulting in a chemical change in the brain (providing an exposure to 10,000 lux of light)
- Vitamin D Supplements – provides Vitamin D when the body is least likely to be creating it’s own Vitamin D due to lack of sun
- Psychotherapy, Talk Therapy
- Share how you are feeling with a trusted friend or family member
