What is seasonal affective disorder?
Recognising the signs and symptoms of SAD
Seasonal affective disorder, or SAD, is sometimes known as the winter blues or winter depression. It’s a mental health condition that mostly affects people during times of year when they are exposed to little natural sunlight.
SAD can make you feel low, tired, lethargic or as though you are wishing your time away. It can be difficult to wake up in the morning, or stay up late after dark. People who work nights or irregular shifts or nights can also experience a similar kind of depression.
