About 5% of American adults experience seasonal , also known as or S.A.D, and it usually lasts about 40% of the year, according to the American Psychiatric Association. .

"SAD is more than just 'winter blues.' The symptoms can be distressing and overwhelming and can interfere with daily functioning," the organization wrote. .

"Some of my clients have reported an increase in depression symptoms," said Dr. Shacunda Rodgers, a clinical psychologist in the Sacramento area. "There are other kinds of stressors, but I've noticed a trend in general that as fall and winter approach, I tend to get more calls versus in the spring and summer."

S.A.D. can occur in the summertime too, however at a lower percentage. According to a Time report, around 1% of the U.S. population experiences seasonal depression in the summer.

What causes seasonal affective disorder?

Specific causes of seasonal depression haven't been pinpointed yet, according to Mayo Clinic.

But with daylight saving time ending in early November, the change in the amount of during the day is a potential factor.

"This decrease in sunlight may disrupt your body's internal clock and lead to feelings of depression," it said on its website.

Reduced sunlight and the change in season can cause a drop in serotonin levels—which affect mood—and impact melatonin levels, important for sleep patterns, in the body.

Rodgers, the Sacramento area , said the fall and winter months can also evoke grief for some because of the holidays.

"Sometimes people's grief is more activated around this time, simply, because you know, they'll have to go through this holiday without that loved one," she said.

Rodgers said that some people may also have difficulty with this time of year because of complications with family relationships.

Risk factors of S.A.D.

Kimberly Miller, a practicing neuropsychologist and owner of Health Mind Sacramento Psychological Services, said that people who have prior depression or tendencies to have are likely to experience S.A.D.

"They might find themselves dealing with listless or low energy or just wanting to sleep more," Miller said, adding that these are symptoms of depression.

According to the Mayo Clinic, S.A.D. is also common among individuals who live further north or south of the equator due to less sunlight exposure in these areas in the winter and longer days in the summer.

Miller said that sunlight is directly tied to seasonal affective symptoms.

People get vitamin D from sunlight, she explained, which affects the chemicals in the brain that are related to mood.

Seasonal affective disorder symptoms range from difficulty concentrating, to changes in appetite and depressed mood, according to the American Psychiatric Association.

And Miller said some may choose cognitive behavioral therapy, which involves changing negative thought patterns into healthy, adaptable thoughts.

She also advised people to exercise.

"Exercise has been shown to be as powerful as taking an , in terms of its ability to improve people's mood," she said. "If you could exercise outside while it's nice, that would also be helpful in terms of getting that vitamin D in you."
