Written by Discovery Senior Living | Oct 17, 2025 4:00:13 AM

Knowing the signs of seasonal affective disorder can help you determine if it's time to seek treatment. Common winter depression symptoms include social withdrawal, overeating, and fatigue.

According to Mental Health America, about 5% of the US population experiences symptoms of seasonal depression. However, many people aren't familiar with the signs of seasonal affective disorder (SAD). Knowing how to spot senior mood changes can ensure you begin treatment before experiencing complications.

You don't have to spend the winter in Independence, IA, feeling down. Instead, read on to learn more about SAD and discover emotional wellness tips for seniors.

What Is Seasonal Affective Disorder?

Seasonal depression, or seasonal affective disorder (SAD), is a form of depression that's triggered by the change of seasons. People usually begin experiencing symptoms in the late fall. It may get worse as the weather gets colder.

Your winter depression symptoms may not improve until the days are sunnier, during the spring.

Some people experience a mild form of seasonal depression, the winter blues. As it gets darker, you may feel a little down.

According to the Cleveland Clinic, between 10 and 20% of people get the winter blues. However, a low mood isn't always indicative of SAD.

Though it's rare, some people experience summer depression. Their symptoms begin during late spring or early summer and don't improve until fall. 

Without treatment, SAD may begin affecting your daily life.You may notice changes to how you:

  • Think
  • Feel
  • Behave

Who Is At Risk of SAD?

You may experience winter depression symptoms if you:

  • Live far north or south of the equator, where there's less sunlight during the winter
  • Live in a cloudy or dark region
  • Having major depressive disorder or another mood disorder
  • Having relatives with depression, another mental health condition, or SAD
  • Are a woman
  • Are between the ages of 18 and 30

Signs of Seasonal Affective Disorder

Remember, SAD is a form of depression. You may experience mood changes and symptoms of major depressive disorder. Common signs of seasonal affective disorder include:

  • Feeling irritated or agitated
  • Craving carbohydrates or sugar
  • Weight gain
  • Anxiety
  • Extreme fatigue and a lack of energy
  • Feeling hopeless or worthless
  • Limbs feeling heavy
  • Oversleeping
  • Loss of interest in once pleasurable activities
  • Social withdrawal
  • Trouble remembering, concentrating, or making decisions
  • Feeling depressed most of the day, almost daily, for at least two weeks

Consult a mental health professional if you experience these symptoms. Don't self-diagnose.

These symptoms don't always indicate seasonal affective disorder. A professional may determine that you have an underlying mental health condition. For diagnosis, they'll determine if you have:

  • Symptoms of SAD or major depression
  • Depressive episodes that happen more frequently during a specific season (winter) than during the remainder of the year
  • Depressive episodes that occur during specific seasons for at least two consecutive years

Senior Mood Support Tips

Making lifestyle changes may improve your mental and physical health. Here are a few emotional wellness tips you can use while navigating SAD.

Soak Up the Sun

Sunlight exposure helps the body produce neurotransmitters related to mood. It can also help you maintain a healthy circadian rhythm (biological clock). Your circadian rhythm regulates your wake-sleep cycle.

Try going for a walk with friends each morning. You can join a walking group through your senior living community's fitness program.

Exercise may boost your serotonin and dopamine levels.These chemicals may help improve your mood and reduce stress. Explore indoor exercise classes, such as:

  • Yoga or chair yoga
  • Pilates
  • Tai chi
  • Weight lifting
  • Resistance training

Eat Nutritious Foods

Explore your senior living community's dining program for nutrient-dense dishes. Plant-based foods offer antioxidants that have neuroprotective properties that may benefit your mood. Look for dishes that feature:

  • Healthy fats
  • Lean proteins
  • Whole grains
  • Nuts and seeds
  • Fruits and vegetables
  • Legumes and lentils

Socialize

Loneliness and social isolation could make your depressive symptoms worse. Instead, explore your senior living community's events and activities calendar. Socializing can boost your mood and foster a sense of belonging. 

Seek Memory Care Support

You can rely on assisted living mental health services and lifestyle programs. Their professional services may reduce stress and improve your quality of life.

Frequently Asked Questions

How Is Seasonal Affective Disorder Treated?

A mental healthcare provider may recommend multiple treatments for seasonal affective disorder, such as:

  • Vitamin D supplements
  • Antidepressant medication
  • Bright light therapy
  • Cognitive behavioral therapy (CBT)
  • Spending time outdoors
  • Psychotherapy (talk therapy)

Sunlight exposure triggers the body's natural production of vitamin D. Vitamin D supports the stimulation of serotonin, a brain chemical linked with mood and sleep.

Let your doctor know if you're already taking medication or supplements. They'll ensure you avoid an interaction. 

Bright light therapy is an effective treatment for SAD. Treatment involves sitting in front of a device that emits 10,000 lux of light (20 times brighter than normal indoor lights). You can get treatment for 15 to 30 minutes each morning to ease depressive symptoms.

CBT is a form of talk therapy that can help you recognize your winter depression symptoms. You can learn how to navigate and manage your symptoms before they affect your quality of life. 

What Causes Seasonal Affective Disorder?

Researchers aren't certain of what exactly causes SAD. However, the lack of sunlight during winter may trigger:

  • Low serotonin levels/a brain chemical imbalance
  • Biological clock changes
  • Vitamin D deficiency
  • Increased melatonin production

Serotonin is a brain chemical (neurotransmitter) that influences mood. Sunlight helps the body produce vitamin D, which aids serotonin production.Low serotonin and vitamin D levels may contribute to your SAD symptoms. 

Melatonin is a chemical that influences sleep patterns and mood. Levels may increase during the darker winter months. Increased melatonin can make you drowsy or affect your mood.
