SAD

SAD is a type of mood disorder in which the depressive symptoms show progression in a seasonal pattern, typically starting in the late autumn and early winter.


The exact cause of SAD is unknown, but researchers have found some biological clues related to a disruption of our circadian rhythms.

Circadian rhythms are metabolic, physical, mental and behavioural changes that follow a daily cycle. One of the most known is the sleep-wake cycle. Scientists believe that a shortage of light may have a negative effect on our sleep rhythms, because it disrupts the regulation of synthesis pathways of important neurotransmitters, such as serotonin and melatonin, as well as the production of Vitamin D.
