SAD 2023

You may have noticed a change in your mood or energy levels now that the hustle and bustle of the holidays are over, the sun isn’t out, and the temperatures outside have dropped. If you find yourself feeling low energy, a lack of motivation, or poor concentration during a specific time of the year, you may be experiencing symptoms of seasonal affective disorder or SAD.

SAD is a diagnosable mental health condition that, if left untreated, can be detrimental to your overall health and well-being. We will look at SAD, including common symptoms, risk factors, prevalence, and treatment options.

What is SAD?

Unfortunately, it is impossible to avoid and prevent feelings of sadness and fatigue. Additionally, it is both normal and common to experience temporary feelings of sadness, low mood, or low motivation. However, when the symptoms of low mood become chronic and start to negatively impact your ability to function in different areas of your life, you may have a diagnosable condition known as seasonal affective disorder or SAD. SAD can impact the way you feel, act, and think. SAD is a form of depression that impacts many people.

SAD refers to a change in your behavior and mood that usually occurs during the late fall or early winter months and resolves during the spring months, and it is a form of depression. Researchers believe that the reduction in sunlight during late fall and early winter months is a catalyst for SAD to develop. Interestingly, SAD can occur during the spring and summer months, which is referred to as summer-pattern SAD.

Symptoms of seasonal affective disorder

SAD is not a distinct diagnosis from depression. Rather it is a form of depression that falls under the category of major depressive disorder or MDD.

Common symptoms of MDD include:

  • Feelings of guilt, hopelessness, or worthlessness
  • Having low energy
  • Feeling fatigued
  • Poor focus and concentration
  • Sleep problems including difficulty falling or staying asleep
  • Hypersomnia or oversleeping
  • Weight loss or weight gain
  • Overeating or undereating
  • Poor appetite
  • Agitation
  • Sluggishness
  • Recurring thoughts of suicide or death
  • Self-harming or suicidal behaviors
  • Anhedonia or loss of pleasure in once-enjoyable activities

Additional winter-pattern SAD symptoms can include:

  • Social isolation or social withdrawal
  • Weight gain
  • Chronic cravings for carbohydrates
  • Over-eating
  • Oversleeping or hypersomnia

Symptoms that are unique to summer-pattern SAD include the following symptoms:

  • Periods of violent behavior
  • Feelings of anxiety
  • Weight loss as a result of low appetite
  • Difficulty sleeping or insomnia
  • Irritability, agitation, or restlessness

Not everyone who has MDD has every symptom listed above. To be diagnosed with SAD, you must experience symptoms of MDD for at least 4-5 months throughout the year.

Risk factors for developing SAD

Like most mental health disorders, there isn’t one specific cause for SAD. However, researchers have identified risk factors that may make you more susceptible to developing SAD.

Risk factors for SAD are listed below:

  • Females are more likely than males to develop SAD.
  • Individuals who live far from the equator and experience cold, harsh winters are more likely to develop SAD than those living close to the equator in tropical climates.
  • Having a family history of depression may make you more likely to develop SAD.
  • Having a chemical imbalance of serotonin in the brain can increase your risk for SAD.
  • Your body making too little Vitamin D and too much melatonin can increase your risk for SAD.

Everyone who has the above-mentioned risk factors are not going to develop SAD. Additionally, researchers believe that sunlight is influential in the development of both patterns of SAD. Too much sunlight contributes to the development of summer-pattern SAD, and too little can contribute to the development of winter-pattern SAD.

Prevalence of SAD in the United States

SAD impacts many people across the United States. Statistics on the prevalence of SAD are listed below:

  • SAD impacts .5 to 3% of the general adult population in the United States.
  • SAD impacts approximately 10-20% of individuals who are diagnosed with MDD.
  • SAD impacts 25% of individuals who have bipolar disorder.
  • Among people with SAD, 10% have the opposite pattern of SAD, where the symptoms occur during the spring and summer months.
  • In roughly 40% of people with SAD, symptoms do not dissipate during the summer months, and they continue after winter has come to an end which would lead to a change in diagnosis.
  • 30 to 50% of individuals with SAD do not experience symptoms for consecutive years.
  • For individuals with SAD, symptoms exist for approximately 40% of the year.

Do I have seasonal affective disorder?

If you think you may be struggling with SAD, there are some things you can look out for. Some common ways symptoms of SAD present in your life may include:

  • You find yourself struggling with feelings or thoughts of low self-esteem or insecurity.
  • You have noticed a reduction in your social engagements, such as hanging out with friends or spending time with your family.
  • You are regularly experiencing cravings for carbohydrates, or you find yourself eating more pasta, bread, or other carbohydrates than during other times throughout the year.
  • You experience passive suicidal thoughts such as “life would be better if I wasn’t alive” or active suicidal thoughts such as “I could take my life by…”
  • You are reacting in anger to situations or circumstances that don’t warrant an anger response.
  • You have lower frustration tolerance than usual.
  • You are having difficulty finding joy in activities that you used to find enjoyable, such as cooking, painting, or exercising.
  • You find yourself feeling fatigued during abnormal parts of the day.
  • You have a hard time focusing on tasks within the home and at work.

Symptoms of SAD can look different for each person, and you should get help if you think you may be experiencing SAD symptoms. The severity of SAD symptoms can vary. If left untreated, SAD can significantly impact your health and overall functioning.

Treatment options for SAD

Talk to your doctor if you think you may be experiencing symptoms of SAD. Your doctor can provide you with an assessment to diagnose SAD, or they can refer you to a specialist who can. Your doctor may also be able to provide you with resources and supports to help manage and treat your symptoms. Remember that you are not alone and that depression of any kind is treatable.

Common treatment approaches for SAD and depression include a variety of interventions such as:

  • Psychotherapy
  • Light therapy
  • Vitamin D
  • Medications

Psychotherapies help you develop the skills necessary to cope with negative emotions and thoughts. Cognitive behavioral therapy, or CBT, is a common psychotherapy that is often used in the treatment of SAD. Treatment occurs in the group setting and includes a group CBT session every two weeks for six weeks.

Light therapy involves you sitting in front of a therapy light for approximately 30-45 minutes each day beginning in the fall and lasting through spring. Therapy lights can usually be found in stores on online retail platforms.

As previously mentioned, vitamin D deficiency has been thought to be a contributing factor to the development of SAD. Therefore, vitamin D supplements may help regulate and improve SAD symptoms. However, research on the efficacy of vitamin D shows mixed results, and it is unclear how effective it is in treating SAD symptoms.

Common medications used to treat SAD include selective serotonin reuptake inhibitors or SSRIs, which are also known as anti-depressants. Common SSRI medications prescribed to treat SAD include:

  • Sertraline
  • Fluoxetine
  • Citalopram
  • Paroxetine
  • Escitalopram
  • Bupropion, which is an extended-release form of anti-depressant

You and your doctor will develop a comprehensive treatment plan that addresses all of your unique needs. Everyone’s treatment plan is different, and interventions that work for one person may not be right for you.
