• To reduce symptoms of seasonal depression
• To have more energy and better mood during the months when the hours of sunshine are at their lowest.

Natural light bath

• Take some air at least 1 hour a day and a little longer on gray days, even in winter. Indoor lighting is very different from the light spectrum of the sun and does not have the same effect as outdoor light.
• Let in as much sunlight as possible inside of his home. Pale colored walls are sure to increase the brightness of a room. You can also place some mirrors in strategic places.

Physical exercise

If done outdoors in daylight, exercise helps prevent seasonal depression. The practice of winter sports also adds a note of pleasure.

Fish consumption

Among Icelanders, we observe little seasonal depression compared to other northern peoples. Some researchers attribute this to their high consumption of fish and fruits of sea². These are rich in omega-3 fatty acids, nutrients that seem to counter depression. Certain gene-related factors are also believed to help keep Icelanders further away from this form of depression.²⁷. These are still hypotheses. At this time, the effect that omega-3 consumption may have on symptoms of seasonal depression is not known.²⁸.
