Many individuals are diagnosed with SAD during the winter months

Many regions of the country have been hit with above average amounts of snow this winter, and there are still approximately two months left in the season. Snow can not only be a travel inconvenience, but also a negative effect on mental health.

Rebecca Davis is one example of an individual who has suffered from depression while living in snowy areas of the country. She has lived in Minnesota, North Dakota and Michigan where snow falls throughout the winter months, according to HealthNews Daily. Eventually, Davis visited a medical professional who linked her depressive symptoms to the season. Now, she splits her time living in New York and Florida.

Seasonal affective disorder (SAD) is also known as the winter blues, which can occur as a result of a lack of sunlight. Although many people associate it with the cold weather season, experts say that it can occur during other times of the year as well. The cause is unknown, but light therapy has proven to be an effective form of treatment.

More than 20 million Americans age 18 and older suffer from mood disorders in the U.S. every year, according to the National Institute of Mental Health. Rehabilitation facilities may be able to help individuals manage their condition over time.
