Other than a few months out of the year between “spring” and “fall” in Alaska, living here poses unique sleeping related to either receiving mostly (or only) daylight or mostly (or only) darkness. These extreme lighting conditions affect our lives in many different ways, most of which can be very disruptive towards sleep.
Extreme light conditions in Alaska can cause sociological, psychological, physiological, and habitual challenges.
These changes can make you two different people, which seems to be the case. Nearly everyone is different between winter and summer. It’s why you might sometimes hear the quip, “Living in Alaska means being two people.” Long winter nights, especially, can cause physical and social habit changes, as well as emotional and mental changes that lead to behavioral changes.
Unfortunately, negative responses to winter often end up either exacerbating or causing the onset of sleep disorders, such as circadian rhythm disorders and insomnia.
Insomnia is the persistent feeling that one cannot get to sleep, stay asleep throughout the night, or are waking up much earlier than desired. Circadian rhythm disorders are a family of sleep disorders affecting the timing of sleep (i.e., disorders affecting your “biological clock”).
Either way, the result is less sleep, and perhaps more fatigue. It’s counterintuitive that a long, dark, cold day could contribute to or worsen a sleeping disorders like insomnia or circadian rhythm disorders.
However, our ability to have a healthy biological clock and sleep pattern is largely regulated by external cues that are much harder to acquire in the long, dark Alaskan winters:
Maintaining a healthy biological clock requires a lot more effort during the winter that if unmanaged, can easily lead to a wonky sleep schedule which can lead to severe sleep deprivation.

Beyond this, other symptoms include [SleepEducation]:
These facts, coupled with the awareness that you are not getting the requisite hours of sleep, may require you to try and mitigate your sleep difficulties.
Many Alaskans use light therapy with great success in combating sleep disorders during the winter. This involves turning on a bright, light therapy lamp in the morning when you wake up and turning it off in the evening about 12 hours later.
Having a strict bedtime routine can help you cultivate the cues that prompt the secretion of melatonin. This could include a bath before bed, certain smells (i.e. essential oils), and a specific activity, such as reading.
Ensuring that you have a restful bedroom is likewise extremely important. This means having a policy about media use in the bedroom, removing your TV and other sources of blue light or distraction, and ensuring your room is quiet and comfortable.
