Do you have seasonal affective disorder? How to tell — and what to do about it

Seasonal affective disorder (SAD) is a type of depression that's linked to changes in seasons, often starting in winter when daylight is shorter. Dr. Norman Rosenthal, who pioneered research on the topic, describes SAD as making people feel like "hibernating bears," with symptoms like fatigue, weight gain, and mood swings. Recognizing these signs is crucial because effective treatments like light therapy, talk therapy, and medication can help manage the condition. Understanding SAD can make a big difference in quality of life for those affected, especially as we navigate the darker, colder months.
