Circadian countermeasures in the high arctic during summer / Michel A. Paul … [et al.].: D68-2/108-2014E-PDF

The study described herein found that regulating outdoor travel and unnecessary exposure to bright nocturnal light can have a positive impact on the sleep quality of Arctic residents. Given the small benefit that melatonin treatment had on several of the research subjects, the prescription of exogenous melatonin may be appropriate for individuals suffering from circadian rhythm misalignment and associated sleep difficulties arising from exposure to nocturnal light that is provocative to the human circadian system. While the improvement in sleep quality from melatonin treatment fell short of statistical significance, it is probable that restricted access to outdoor evening light resulted in relatively normal sleep in our current subjects. This is in stark contrast to the sleep hygiene of the subjects evaluated in June 2012. Improving sleep quality and minimizing insomnia among the military residents of the Arctic will have a significant positive impact on the cognitive effectiveness of these individuals.
