- Shorter daylight hours primarily affect the brain's circadian clock, leading to sleep disruption and fatigue.
- Daylight length is the strongest environmental factor, with temperature playing a minor role.
- Women are twice as susceptible as men, and living at higher latitudes increases risk.
- A family history of depression raises an individual's risk for developing SAD.
- SAD symptoms typically peak in January and February, often lasting about five months annually.
- Dr. Kelly Rowan identifies light therapy, antidepressant medications, and cognitive behavioral therapy (CBT) as effective treatments.
- Light therapy involves daily exposure to 10,000 lux artificial light to regulate circadian rhythms, simulating early dawn.
- CBT for SAD focuses on reframing negative winter thoughts and promoting active, joyful behaviors over passive hibernation.
