One hypothesis some suicide researchers have floated is that suicide has multiple aspects; the dark winters damage people emotionally while reducing energy, and then when the light comes flooding back, their energy levels recover before their emotions. Result: suicide. Apparently there&#x27;s some analogies in depression treatment where you&#x27;re briefly more likely to commit suicide after a treatment starts working. Here&#x27;s one paper on the topic: Vyssoki et al 2014 <a href="http:&#x2F;&#x2F;www.gwern.net&#x2F;docs&#x2F;2014-vyssoki.pdf" rel="nofollow">http:&#x2F;&#x2F;www.gwern.net&#x2F;docs&#x2F;2014-vyssoki.pdf</a> &quot;Direct Effect of Sunshine on Suicide&quot;. There might be something similar at play in Greenland.
