It is that time of year when the days are shorter and the temperature drops. For some, this is a welcome change that brings the excitement that comes along with outdoor winter activities and the holiday season. For others, this time of year can be very tough and could result in Seasonal Affective Disorder (SAD)—a condition that many may or may not know they are dealing with.

Seasonal affective disorder consists of a subset of disorders that are caused by mood and biochemical disturbances that have a seasonal pattern. The most common form is seasonal depression. SAD can affect up to 5 percent of the population, but it can be as prevalent as 10 percent in northern latitudes where the weather is colder and sunlight is harder to come by. In northern regions with extended winter conditions, patients with SAD can have symptoms up to 40 percent of the year, greatly impacting their quality of life.

Symptoms of SAD can mirror typical symptoms of depression, which include sadness, guilt, hopelessness, lack of energy, fatigue, sleep problems, weight gain or loss, lack of interest in activities, and difficulty concentrating. However, with SAD, most people recognize or can trace a pattern to the seasons. For example, symptoms tend to arise in fall and winter and go away, even without treatment, in spring and summer. Others, although less common, experience symptoms in the spring and summer with remission in the colder months.

There are several treatment options for SAD, including phototherapy. This form of therapy promotes exposure to light for set periods of time using light boxes that can be purchased online or at local stores. This treatment, also known as light therapy, can significantly improve mood in one to two weeks. Other beneficial practices include exercise, relaxation techniques, and spending more time outdoors, especially during daylight hours. Sometimes treatment options include prescription medications and/or cognitive behavioral therapy. These treatments can be done alone or in combination with each other.

With the ongoing pandemic, these symptoms can be exacerbated as social isolation is worse than during a typical winter. People may also be experiencing more anxiety and stress as they cope with making it through this winter while attempting to remain connected to what matters most—people.
