Seasonal affective disorder (or SAD) affects many of us, as our energy levels undergo a gradual change from summer to autumn. Dark, chilly mornings make it harder to get out of bed, and it’s common to feel more lethargic and crave comforting foods as we adjust to the change in seasons.
Some of us simply put this down to the ‘winter blues’ but, for others, the symptoms can be far more debilitating, preventing us from functioning normally for almost half the year.
Since the 1980s, this type of winter depression has been known as Seasonal Affective Disorder (SAD).
Figures suggest that around 2m people in the UK are affected by SAD every winter between September and April, with symptoms peaking in December, January and February.
