Shorter days and dark afternoons can trigger depression. Here's how to fight back

Key Points:

• Seasonal Affective Disorder (SAD), first described and named in 1984 by Dr. Norman Rosenthal, is a condition that affects more women than men and shares symptoms with depression, such as hopelessness and difficulty concentrating.
• Research indicates that people with SAD have reduced sensitivity to blue light, which is critical for activating brain centers related to mood and alertness, especially during shorter winter days.
• Light therapy, involving exposure to bright light (around 10,000 lux) for 30 minutes each morning, is an effective treatment for many with SAD and milder winter mood issues, though product quality varies and insurance may cover costs.
• Additional treatments include antidepressant medications, maintaining regular sleep schedules, outdoor activity, and cognitive behavioral therapy (CBT), which offers longer-lasting benefits by helping patients change negative thought patterns.
• Experts recommend combining these approaches and engaging in enjoyable, low-pressure activities to combat the effects of SAD and improve overall well-being during winter months.
