Do you have seasonal affective disorder? How to tell - and what to do about it
NPR • • health
Key Points:
- Seasonal Affective Disorder (SAD) affects about 1 in 20 people in the U.S., causing symptoms like depression, oversleeping, overeating, and low energy during darker months, typically lasting about 40% of the year.
- Light therapy using SAD lamps, which emit intense light mimicking natural sunlight, is a common and effective treatment; exposure for 20-30 minutes each morning can improve symptoms within two weeks.
- Managing diet by avoiding late-night eating and maintaining consistent meal times helps regulate the body's circadian rhythm, which is often delayed in people with SAD.
- Regular exercise during the active part of the day serves as a cue to the body's internal clock, helping to improve mood and energy levels despite cold and dark conditions.
- Reducing stress through methods like therapy, meditation, and making pleasurable plans is important, and medication may be necessary if symptoms significantly impact daily life or relationships.
