Medical science has shown that the short days and lack of sunlight in northern latitudes can have negative physical and emotional effects on some people. In fact, seasonal affective disorder, or SAD, is treated by doctors and therapists as a real and potentially life-threatening condition.

According to the online site American Family Physician by the American Academy of Family Physicians, roughly 4 to 6 percent of the population suffers from SAD, also known as “winter depression.”

Four times more common in women than in men, it often does not appear until a person is in their 20s, and its impact does decrease with age, according to Dr. Amy Movius at Eastern Maine Medical Center, who adds the chances of being hit with SAD increase the farther north a person lives.

“In Maine we are at risk because we have such short days,” Movius said. “It can be dangerous. It’s like any form of depression, but in this case people notice it seasonally when they feel down, lose interest in things, do not sleep well, their heads are all foggy and there can even be thoughts of suicide or self-harm.”

Symptoms can also include changes in appetite, with cravings for sweet and starchy foods, weight gain, a “heaviness” in the arms and legs, reduced energy levels, fatigue, a tendency to oversleep, difficulty concentrating, irritability, increased sensitivity to social rejection and a tendency to avoid going out at all.

Exposure to sunlight is important as it helps the release of the neurochemical serotonin in the brain which is associated with healthy moods. Serotonin levels impact sleep patterns, appetite, memory and learning and those levels can dip without enough sunlight exposure, resulting in SAD.

According to online weather data computed by the U.S. Navy, Bangor averages less than nine hours of sunlight per day in December, assuming there is no cloud cover, which can be the case about 50 percent of the time.

By March the amount of daylight in Greater Bangor is up to around 10 hours and continues to increase until the longest day of the year in mid-June, when there are more than 15 hours of daylight.

Those darker months can be a real issue for those affected by SAD.

But rather than doing like the bears and hibernating away the dreary months of winter, there are other, more healthy options.

“I am a huge believer in self-care,” Movius said. “Practice good nutrition, with a good diet, and try to get exercise and expose yourself to sunlight as much as you can.”

For those days when getting outside is an issue or when there is no sunlight, use of specialized light boxes that simulate sunlight is an alternative. These boxes can be purchased online through or at most major retail department stores.

When using so-called “light therapy,” an individual sits in front of a specialized light box for about 30 minutes per day during the late fall and through the winter. The best kind of light to use can be recommended by a therapist or doctor

Adding vitamin D, normally absorbed by the body from sunlight, via supplements can also help battle SAD.

“I’m a huge fan of vitamin D, it’s one of my favorite supplements,” Movius said. “At this latitude, we are all vitamin D deficient, even if you do get outside because of that lack of sunlight. Everyone in my family gets nagged daily to take their vitamin D.”

Vitamin D supplements are available over the counter. from most pharmacies and drug stores.

Movius stresses that if a person suspects they may be suffering from SAD that they should consult with a medical or mental health provider not try to go it alone.
