Some scientists argue that SAD came about as a winter evolution mechanism in human beings, specifically a variation of hibernation in some distant ancestor. Theoretically, food was hard to come by during this time of the year and a tendency towards low mood may have been used adaptively to cut back on caloric intake.
Another possible explanation is that snow season naturally leads to drastic reduction of Vitamin D in the body, given that insufficient amounts of Ultraviolet-B rays are reaching the skin. This is believed to trigger depression in the long run.
Physical exercise is one of the most effective forms of treatment for this malady, particularly when combined with other alternative remedies such as bright light therapy. In a certain control test, patients who maintained a regular training regime of about 20 min per day witnessed faster recovery than the rest. Making scientists to conclude that regular training actually helps in curbing the effects of SAD.
Alternatively, -VE air ionization technique can be used instead of the above method. This technology is meant to mimic summer-like conditions by gradually supplementing the sparse winter ion ratio, the machine can be bought from authorized stores online.
Though some air-purifiers currently being sold in the market utilize negative ion dispensation, experts warn that average dosage of ions delivered by standard home purifiers are way too low to trigger any antidepressant effects.
