Poor mood in winter is linked to lack of light
Scientists have pinpointed seasonal changes in brain chemistry which may cause some people to suffer from the winter blues.
Seasonal affective disorder, which can be debilitating, is linked to lack of light exposure on short winter days.
The latest study suggests this might make proteins which clear the brain of the mood-regulating chemical serotonin more active.
The University of Toronto study appears in Archives of General Psychiatry.
Seasonal affective disorder is linked to lack of energy, fatigue, overeating and a tendancy to sleep longer as well as depressed mood.
The condition affects thousands of people in the UK.
