What is SAD?

SAD (Seasonal Affective Disorder) is a type of winter depression that affects an estimated half a million people every Winter between September and April, in particular during December, January and February.

It is caused by a biochemical imbalance in the hypothalamus due to the shortening of daylight hours and the lack of sunlight in winter.

For many people SAD is a seriously disabling illness, preventing them from functioning normally without continuous medical treatment.

For others, it is a mild but debilitating condition causing discomfort but not severe suffering. We call this subsyndromal SAD or 'winter blues.'
