How to treat Alaskan Winter Insomnia

Why Alaska Winter Darkness Can Cause Insomnia

Alaskan winters mean extreme lighting conditions: mostly or entirely dark all day. Despite what you might immediately think, all this darkness is actually not good for sleep for many of us who live in Alaska. Transitioning to Alaska darkness from our summers means making big changes to our lives. Furthermore, there are natural hormonal changes that take place during the long dark winters that further inhibit our ability to get restful sleep.

Our lives tend to change drastically between summer and winter to the point where it may seem like we are different people. The winters can hit many of us particularly hard:

  • Anxiety
  • Depression
  • Restlessness
  • Feelings of isolation
  • Low levels of physical activity
  • Little time outside
  • Hormonal changes

These symptoms often end up either exacerbating or causing the onset of sleep disorders, most commonly insomnia. In addition to these natural responses to the darkness, our melatonin regulation can also be profoundly changed during all of the darkness.

Melatonin regulates our biological clock. It is produced in response to changes in light. The lack of light changes during winter can throw our melatonin regulation completely off, and combined with other factors, causes our sleep schedules to thrown off as well. This can lead to the development, or exacerbation of classic insomnia signs, including: 

  • Can’t fall asleep
  • Can’t sleep until a normal hour in the morning
  • Keep waking up throughout the night

Although you can't control the weather and the changes in light, there are steps you can take to ward off insomnia, including: 

Use Light Therapy

Light therapy is used to treat insomnia or sleep problems. Due to the fact that changes in light are extremely important for regulating sleep and combatting erratic sleep cycles, one of the best things to prepare for and prevent insomnia during Alaskan dark winters is to start using light therapy.

Light therapy is simply using a light box that includes:

  • Bright fluorescent light bulbs (about 10,000 lux)
  • A box to encase the light
  • A diffusing screen to make the light diffuse (like sunlight)

This simulates natural light exposure and is safe for the eyes. You can use this light box in virtually any capacity, such as:

  • Next to your computer at work
  • When you do you morning routine to get ready (read, eat breakfast, put on makeup, etc.)
  • Reading
  • Eating meals like dinner

The main idea behind light therapy is to simulate and control artificial sunlight. Timing is everything. You should:

  • Begin using light therapy when the amount of darkness is greater than light (in Anchorage, this starts in October)
  • Start exposing yourself to your light box in the morning when you wake up
  • Stop exposing yourself to your light box in the evening, just after dinner.

Here are some tips on light therapy:

  • Use this Alaska daylight hours calculator to see at what time of the year you should start using light therapy
  • Make sure to pay attention to the intensity of your light box
  • Less intense light boxes (i.e., 2,500 lux) will require more exposure

Change Lifestyle Habits

Lifestyle habits also play a role in preventing insomnia. A few areas where people are commonly successful in combating insomnia in the winter are:

  • Drinking habits (alcohol and coffee)
  • Exercise habits
  • Consistent routines

As far as drinking habits, try to practice the following, as they all will help prepare you for sleep:

While it’s easy to get outside in the summer, winter will require doing things differently. Namely, you should work hard to:

  • Find an outside activity that you enjoy in the winter and can do regularly
  • Do regular activities at a local gym, such as swimming, working out, basketball, etc.

Finally, consistent routines involves trying to change your habits and routines as little as possible between summer and winter. This will help avoid “shocking” your body by drastically changing your schedule and habits.

Create Perfect Bedroom for Sleeping

A restful bedroom is extremely important for ensuring that you have no distractions keeping you from sleep. The main ways to have a restful bedroom are:

  • Very dark room
  • Quiet room – use earplugs or white noise as necessary
  • Tidy room with relaxing decor
  • Clean room
  • Good smelling room
  • Electronics free room
  • Comfortable, high end pillow (can be acquired for about $35)
  • Comfortable sheets
  • Nice mattress or mattress topper

You want your room to give you that warm and fuzzy feeling, like walking into a spa, that will help condition you for sleep when you get into bed.

Develop Bedtime Routine

A bedtime routine is designed to queue your body’s melatonin production, nervous system relaxation, and mental relaxation – all of which condition your body to prepare for sleep. Your routine should:

  • Include the same activities every evening
  • Be at similar times every evening
  • Be practiced religiously

Some common routines include:

  • A warm bath before bed
  • Using same aromatherapy scent before bed
  • Performing a ritual activity, like mediation or stretching
  • Reading, or any other relaxing activity
  • Avoiding electronics at all cost

Consulting with a sleep specialist to express concerns, difficulties, or seek further guidance is also an extremely effective way of ensuring that your sleep preparation is curtailed to your unique sleep struggles.
