Constant Sunlight behind Greenland Suicides?/Seasonal affective Disorder

In Greenland, the summers are filled with incessant daylight and scientists say this is the very reason why there is a alarming rise in the number of suicides in that place.This comes from research data accumulated by the Karolinska Institute in Sweden, by a team led by Karin Sparring Bjorksten.which studied the seasonal variation of suicides in all of Greenland from 1968 to 2002.
This is very interesting data for those having an interest in suicidology. It was found that there was a concentration of suicides in the summer months and that the seqasonal effect was specifically more in the north of the country- an area where the sun doesn't set between the end of april and the end of august. In terms of seasonal light variation Greenland is the most extreme human habitat.Greenland is also reckoned to have the highest suicide rate in the world. The research document also records that suicides were almost exclusively violent and increased during periods of constant day. In the north of the country 82% of suicides occurred during daylight months (including astronomical twilight). Most suciides occurred in young men, 95% of the suicides occurred by using violent means like shooting, hanging and jumping from heights. The researchers speculated that light-generated imbalances in the turnover of neurotransmitter serotonin could lead to increased impulsiveness, which in combination with lack of sleep could explain the increased rate of suicides in the summer months in Greenland.
Sounds like seasonal affective disorder can lead to greater propensity to suicide. There are people who get affected by sunmmers, some by winters and some even by the monsoons. Seasons always have had a kind of affect(negative and positive) on the human psyche.People who call us also tell us the same. Of course almost everyone who calls a suicide helpline confesses to being affected by seasonal changes. In the monsoon the head feels heavy, mood is low and there's general malaise and disinterest.In the summer the feeling is of ennervation and lack of energy while in the winter feeling is of gloom and doom. A fragile mind finds it difficult to cope with these pervasive and invasive affectations and this leads to a fracture in the cope-ability of the person!
