Seasonal affective disorder (SAD) is a type of depression that comes and goes in a seasonal pattern.
SAD is sometimes known as "winter depression" because the symptoms are more apparent and tend to be more severe during the winter.
The symptoms often begin in the autumn as the days start getting shorter. They're typically most severe during December, January and February.
SAD often improves and disappears in the spring and summer, although it may return each autumn and winter in a repetitive pattern.
Symptoms of SAD can include:
- a persistent low mood
- a loss of pleasure or interest in normal everyday activities
- feelings of despair, guilt and worthlessness
- feeling lethargic (lacking in energy) and sleepy during the day
- sleeping for longer than normal and finding it hard to get up in the morning
- craving carbohydrates and gaining weight
