Do you feel more sluggish or withdrawn as the seasons change? You could be dealing with Seasonal Affective Disorder (SAD)—a form of depression linked to changes in daylight and temperature.
What Is Seasonal Affective Disorder?
SAD is a recurring type of depression that typically starts in the fall and lasts through winter, though some people experience symptoms in the spring or summer. It’s caused by disruptions in your circadian rhythm and changes in brain chemistry due to reduced light exposure.
Key symptoms include:
- Persistent low mood
- Fatigue and low energy
- Loss of interest in activities
- Trouble sleeping or oversleeping
- Appetite changes (especially sugar/carbohydrate cravings)
- Difficulty concentrating
- Feelings of hopelessness
Spring and summer SAD can include insomnia, irritability, or weight loss—making it important to track when your symptoms occur each year.

Causes of SAD
Reduced daylight plays a major role by disrupting your body’s internal clock (circadian rhythm) and altering serotonin and melatonin levels. You may be at greater risk if you:
- Live far from the equator
- Have a personal or family history of depression
- Are female (SAD is more common in women)
How Is SAD Treated?
There are several effective treatment options:
- Light Therapy: Daily use of a light box (10,000 lux) can improve mood and reset your sleep-wake cycle.
- Talk Therapy: Cognitive Behavioral Therapy (CBT) helps you identify and change negative thought patterns.
- Medication: Antidepressants may be prescribed, particularly if your symptoms are severe or long-lasting.
- Lifestyle changes: A healthy diet, regular physical activity, and stress reduction all support better mental health.
