Winter Depression: A Complete Guide to Seasonal Affective Disorder (SAD) Risk Assessment

What Is Seasonal Affective Disorder (SAD)?

Seasonal Affective Disorder (SAD) is a type of depression that follows seasonal patterns, typically worsening during winter. It affects 5% of adults in the U.S., with symptoms like low energy, mood swings, and difficulty concentrating. Our Winter Depression (SAD) Risk Calculator helps identify vulnerability through scientifically validated parameters.

Key Factors in SAD Risk Calculation

1. Sunlight Exposure

Definition: Hours of direct daylight exposure per day.
Why It Matters: Reduced sunlight disrupts circadian rhythms and serotonin production.

• Optimal: 1–2 hours daily

• High Risk: <30 minutes

2. Sleep Duration

Definition: Average nightly sleep hours.
Why It Matters: Irregular sleep worsens melatonin imbalance.

• Ideal: 7–9 hours

• Risk Factor: <6 or >10 hours

3. Family History

Definition: Genetic predisposition to mood disorders.
Why It Matters: 30% of SAD cases have familial links.

4. Previous SAD Episodes

Definition: History of seasonal depression.
Why It Matters: Recurrence rates exceed 50% without intervention.

5. Stress Levels

Definition: Self-reported mental strain (1–10 scale).
Why It Matters: Chronic stress amplifies seasonal mood changes.
