Seasonal Affective Disorder (SAD)

What is Seasonal Affective Disorder (SAD)?

Seasonal Affective Disorder (SAD) is a type of depression linked to seasonal changes, most commonly developing during the fall and winter months when daylight hours decrease. Individuals experiencing seasonal affective disorder symptoms may notice changes in mood, energy, motivation, and sleep patterns as natural sunlight exposure declines.

Seasonal depression shares many similarities with Major Depressive Disorder, but follows a recurring seasonal pattern. Symptoms often return during colder, darker months and improve as the seasons change, making early recognition and seasonal affective disorder treatments especially important.

Seasonal Affective Disorder vs. the Winter Blues

Many people experience temporary fatigue or low motivation during colder months, often referred to as the “winter blues.” However, seasonal affective disorder symptoms are typically more severe, persistent, and disruptive to daily life. Individuals with SAD may experience symptoms such as:

• Significantly depressed mood
• Anhedonia: Difficulty enjoying things that one typically enjoys, or difficulty feeling positive emotions.
• Feelings of hopelessness
• Decreased confidence and lower self-esteem
• Crying spells
• Difficulty with focus and concentration
• Significantly lower energy and motivation
• Changes in appetite, or unexpected fluctuations with weight
• Decreased libido
• Disturbances with sleep (excessive sleeping, insomnia, or broken sleep)
• Suicidal thoughts
  • Call 911 or 988 if you experience suicidal thoughts
• Others

Seasonal Affective Disorder, and the episodes of depression that it causes, are treatable medical conditions – not just a desire to stay inside, when the climate isn’t ideal.

How Common is Seasonal Affective Disorder or Winter Depression?

• Millions of Americans (5% of the US population) experience seasonal affective disorder symptoms each year.
• SAD is more common in areas with long, dark winters and reduced sunlight exposure.
• Women and younger adults are more frequently affected by seasonal depression.
• While many people notice mild seasonal mood changes, SAD symptoms can significantly interfere with daily functioning and quality of life.

What are Risk Factors for Developing Seasonal Affective Disorder?

Several biological, environmental, and mental health factors may increase the likelihood of developing Seasonal Affective Disorder, including:

• A diagnosis of another mood disorder, such as Major Depressive Disorder (MDD) or Bipolar Affective Disorder (BPAD).
• A family history of Major Depressive Disorder, Bipolar Disorder, or SAD.
• Residing in latitudes far north, or south, of the equator (where there’s less natural sunlight) – or living in predominantly cloudy regions.
• Vitamin-D Deficiencies: Sunlight increases Vitamin D, and a lack of sunlight may reduce it, which can affect serotonin (a healthy neurotransmitter, that affects mood).

What is Photo-Therapy or Light Therapy for Seasonal Depression?

Light therapy, also known as phototherapy, is one of the most common seasonal affective disorder treatments. This approach uses specialized light boxes that mimic natural sunlight to help regulate mood, energy levels, and sleep cycles during darker months.

• Treatments are typically 30- 60 minutes most mornings.
• Recommended lights are 10,000 Lux (full-spectrum).
• Lights should have appropriate UV filters (to protect against skin cancer, eye-damage, and/or other health risks).
• Lights must typically be large and/or within close proximity (6- 24 inches) of a person’s face. Specific lights have specific requirements.
  • Use a reputable company, and follow all recommended instructions.
• The light must enter through the person’s eyes, triggering a decrease in melatonin production in the brain (pineal gland) and increasing healthy brain chemicals, such as serotonin.
• Lights should be used in the mornings or early in the day, as they could disrupt a person’s sleep-wake cycle and circadian rhythm.

*Light therapy is not without risks. We recommend that individuals are supervised or under the guidance of a mental health professional, when using these products, particularly if they have Bipolar Affective Disorder (BPAD) or an insomnia disorder.

**If an individual has moderate to severe symptoms of depression, we greatly advise that they consult with a mental health professional, as additional treatment beyond light therapy may be indicated.

Additional Seasonal Affective Disorder Treatments

Effective seasonal affective disorder treatments are personalized to each individual’s symptoms, lifestyle, and mental health needs. Treatment options may include:

• Medication Management: Such as SSRIs/ SNRIs/ Wellbutrin (Buproprion) and other anti-depressant medications.
• Psychotherapy
• Phototherapy / Light Therapy (discussed above)
• Behavioral Modification and activation: Such as recommendations for diet, exercise, additional time outside, sleep hygiene and others.

Regular physical activity may help reduce seasonal affective disorder symptoms by improving mood, energy, and sleep quality. Many individuals benefit from consistent aerobic exercise several days per week as part of a comprehensive treatment plan.
