# Why Does My Mood Change in the Fall? Understanding Seasonal Depression in Columbia, Maryland

Fall in Columbia brings cooler temperatures, changing leaves, and shorter days. For some people, it also brings an unexpected change in mood, energy, sleep, and motivation. Feeling a little different as the seasons change is common, but recurring depression during the fall and winter months can sometimes point to seasonal affective disorder.

Seasonal affective disorder (SAD) is a form of depression with a recurring seasonal pattern. According to the National Institute of Mental Health, winter-pattern SAD most often begins in late fall or early winter and improves during spring or summer. A less common form, sometimes called summer SAD, follows the opposite seasonal pattern.

If the arrival of fall consistently makes life feel harder, understanding the difference between the winter blues and seasonal depression can help you decide when it may be time to talk with a mental health professional.

## **Why Can Mood Change When Fall Arrives?**

Researchers are still studying exactly what causes seasonal affective disorder (SAD). What we do know is that winter-pattern SAD is linked to changes in daylight and biological systems that help regulate mood and sleep.

Less daylight can affect serotonin, one of the brain chemicals involved in regulating mood. Seasonal changes may also affect melatonin and the circadian rhythm, the body’s roughly 24-hour sleep and wake cycle. When that internal clock has difficulty adjusting to changes in sunlight, some people experience changes in sleep, energy levels, behavior, and mood.

That does not mean every difficult autumn day is seasonal depression. Stress from school schedules, work demands, holidays, family responsibilities, or other life changes can also affect mental health.

## **Winter Blues vs. Seasonal Affective Disorder**

The winter blues usually describe relatively mild changes in mood or energy as the days become shorter. You may feel less motivated, prefer staying home, or notice that winter feels harder, while still being able to manage your responsibilities.

Seasonal affective disorder is more significant. SAD is a type of depression in which depressive symptoms follow a recurring seasonal pattern and interfere with how a person feels, thinks, or functions. NIMH notes that symptoms generally last about four to five months of the year.

If symptoms are persistent, distressing, or interfering with work, relationships, responsibilities, or your quality of life, consider speaking with a mental health professional.

**If fall feels noticeably different for you every year, counseling can provide a place to understand those patterns. Focused Solutions offers individual therapy with licensed clinicians at our Columbia office. [Contact us today.](https://focused-solutions.com/contact-us/)**

## **What Are Common Seasonal Depression Symptoms?**

Seasonal depression includes many of the same symptoms associated with major depression. These can include a persistent depressed mood, loss of interest in activities, difficulty concentrating, feelings of hopelessness, fatigue, and changes in sleep or appetite.

Winter-pattern SAD can have additional symptoms, including oversleeping, social withdrawal, overeating, cravings for more carbohydrates, and weight gain. Someone may notice lower energy levels and feel as though they want to “hibernate” during the winter months.

Not everyone who experiences SAD will have all of these symptoms. Likewise, symptoms can look different from person to person.

## **When Should You Consider Talking to Someone?**

Pay attention to both the severity and the pattern of your symptoms. A few low-energy days in early fall are different from depression symptoms that repeatedly return at roughly the same time each year.

A diagnosis of seasonal affective disorder requires more than feeling down when the weather changes. NIMH explains that depressive episodes must occur during a particular season for at least two consecutive years and be more frequent during that season than at other times.

You do not need a diagnosis before asking for support, however. If changes in mood, sleep, motivation, or energy are making daily life more difficult, therapy can help you explore what may be contributing.

## **What Helps With Seasonal Depression?**

Seasonal depression treatment can involve several treatment options. The National Institute of Mental Health identifies light therapy, psychotherapy, antidepressant medications, and vitamin D as areas used or studied in SAD treatment. The right approach depends on an individual’s symptoms, health history, and clinical needs.

Talk therapy is one option that does not involve prescribing medication. Cognitive behavioral therapy has been adapted specifically for SAD. CBT-SAD helps people recognize unhelpful thoughts about the season and uses behavioral activation to encourage meaningful and enjoyable activities. NIMH reports that CBT-SAD and light therapy have both demonstrated benefits, with CBT showing potentially longer-lasting effects in follow-up research.

## **How Does Light Therapy Work?**

Light therapy is a common treatment for winter-pattern seasonal affective disorder. Light therapy involves sitting near a specially designed light box that produces bright light intended to compensate for diminished natural outdoor light.

NIMH describes using a 10,000-lux light box for about 30 to 45 minutes, usually first thing in the morning. NCCIH describes a typical range of 20 to 60 minutes each morning. A properly designed light therapy box filters potentially harmful ultraviolet light.

Light treatment is not appropriate for everyone. Certain eye conditions, medications that increase light sensitivity, and bipolar disorder may require additional medical guidance. If you are considering light therapy, discuss it with an appropriate health care provider rather than assuming any bright light or commercially available device is suitable.

## **Can Lifestyle Habits Help Manage Seasonal Depression?**

Lifestyle changes may support mental health alongside professional treatment. NIMH encourages spending time outside in sunlight for milder seasonal symptoms, while NCCIH identifies replacing diminished winter sunlight as part of the rationale behind light therapy.

Regular exercise, staying active, consistent sleep patterns, and healthy eating can also support overall wellness. Maintaining enough sleep and regular physical activity can be particularly useful when winter begins disrupting normal routines. Balanced meals, including foods with complex carbohydrates rather than relying primarily on highly sugary foods, can also support general health.

Natural daylight may still be worth seeking on cloudy days. Sitting near bright windows can feel pleasant, but ordinary indoor light is much dimmer than a therapeutic light box and should not be treated as a substitute for prescribed light therapy.

## **What About Vitamin D and Antidepressants?**

People with winter-pattern SAD may have lower vitamin D levels, but evidence on vitamin D supplementation as a treatment is mixed. NCCIH states that vitamin D is not considered an established primary treatment for SAD. If a deficiency is suspected, testing and supplementation decisions should be discussed with an appropriate medical provider.

Antidepressants can also be used in the medical treatment of SAD, including certain SSRIs and, in some circumstances, extended-release bupropion. These are prescribing decisions for a qualified medical provider. Focused Solutions provides counseling and psychotherapy and does not prescribe or manage antidepressants.

## **How Therapy Can Support You Through the Winter**

Therapy can provide practical support when seasonal changes begin affecting your thoughts, habits, relationships, and daily functioning. A therapist can help you identify patterns, address unmanaged stress, build coping strategies, and find ways to remain connected with activities and people that matter to you.

Focused Solutions’ Columbia clinicians provide evidence-based, individualized counseling for concerns including depression and anxiety. In-person, virtual, and hybrid therapy options are available through the Columbia location.
