Expert: The science behind seasonal mood changes
Seasonal Affective Disorder (SAD) is a type of depression linked to the changing seasons, particularly during fall and winter when daylight hours decrease. The reduced sunlight and lower vitamin D levels can lead to changes in mood, energy and sleep patterns. As well, the recent change back to standard time from daylight savings can disrupt circadian rhythms, with similar results.ÌýÌý
