I can’t say - but, living in Alaska, especially in the winter months, and suffering from depression seem to go hand-in-hand for many people.
True..... and there's apparently a genetic component for certain types of depression, which would almost certainly be exacerbated by the months-long Alaskan winter night.
Lack of sunlight seems to exacerbate depression and is the main cause of one type of depression (seasonal affective disorder). Deficient production of “vitamin” D (actually a hormone) may be involved.
Good idea SoldierDad.
If ya’ve ever been to say North Idaho or Montana you know it can stay light or dark for 16 or 18 hours a day and in Alaska it can be even worse.
Some folks just can’t adjust to constant darkness.
Seasonal Affective Disorder (SAD).
This business of a lack of Vitamin D in the winter contributes to a condition called S.A.D.D. that goes along with spending little or no time in the sun (which you can’t in the winter months). Spending a bit of time (just ten min. or so a day) in the sun with a good bit of skin exposed makes the body produce Vitamin D. - I’m taking a Vit. D. pill (2000 mg.) every day in the cold weather, and will get out in the sunshine a bit when it gets past the cool and cold weather here. One CAN overdose on Vitamin D, so don’t overdo it. I can say that I do think it helps me to not be depressed.
