SAD is sometimes known as “winter depression” because the symptoms are usually more apparent and more severe during the winter. Seasonal affective disorder (SAD) is a type of depression that comes and goes in a seasonal pattern. A few people with SAD may have symptoms during the summer and feel better during the winter.
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
