Diminished light in the winter can result in what's known as Seasonal Affective Disorder or 'SAD'which is most commonly associated with depression in the late fall or the winter. Now, most people start feeling better in the spring. People who get sad may be genetically prone to the issue. But diet, stress, gender, and age are also being considered as factors. For now, we tend to see a higher rate of sad in those who already have an underlying mental illness such as anxiety, bipolar disorder, or add.
Now if you think might be suffering from Seasonal Affective Disorder, you need to seek treatment. Treatment options include light therapy, medication, counseling and a close follow up to monitor long term progress. I urge you to please seek treatment if you or someone you know may need assistance. I'm Dr. Janette Nesheiwat.
