Seasonal affective disorder (SAD) - Symptoms
The symptoms of seasonal affective disorder (SAD) are like the symptoms of normal depression. But they occur repetitively at a particular time of year.
They usually start in the autumn or winter and improve in the spring.
The nature and severity of SAD varies from person-to-person.
Some people just find the condition a bit irritating. For others, it can be severe and have a significant impact on their day-to-day life.
Most people with SAD will feel depressed during the autumn and winter.
Signs that you may be depressed include:
- a persistent low mood
- a loss of pleasure or interest in normal everyday activities
- feeling irritable
- feelings of despair, guilt and worthlessness
- low self-esteem
- feeling stressed or anxious
- a reduced sex drive
- becoming less sociable
A small number of people have these symptoms in phases that are separated by "manic" periods. During these, they feel happy, energetic and much more sociable.
You may also:
- be less active than normal
- feel lethargic (lacking in energy) and sleepy during the day
- sleep for longer than normal and find it hard to get up in the morning
- find it difficult to concentrate
- have an increased appetite
These symptoms may make everyday activities increasingly difficult.
