In Finland, there is a clear increase in the number of sick days taken due to depression, anxiety and sleep disorders in October and November, whereas the number of absences is lower than expected between June and September. In late autumn, the number of sick days taken is almost twice as high as in the summer and about a quarter higher than in early autumn. On the other hand, manic episodes related to bipolar disorder occur more frequently than expected during the spring and summer, when there are more daylight hours, and less frequently than expected during darker times of year.
The results can be found in a study funded by the Research Council of Finland. The study was conducted as a part of the Climate Change and Health research programme. The aim of the study was to investigate the connection between changing light levels and mental health. It is expected that due to climate change, winters in Finland will become darker while summers will become brighter.
