Seasonal Affective Disorder, also called SAD, is a type of depression that happens at certain times of the year. Most people feel it during the fall and winter when there is less sunlight. Some people may feel it in the summer, but that is less common.
This condition is more than just the “winter blues.” It can affect your mood, sleep, energy levels, and ability to enjoy life. SAD is a real mental health condition, and it should be taken seriously.
Why Does Seasonal Affective Disorder Happen?
Experts believe that SAD is caused by changes in light exposure. When the days become shorter and darker, it affects the body’s biological clock, also known as the circadian rhythm. This can lead to a drop in mood-regulating brain chemicals like serotonin and melatonin.
How Light Affects Mood
Sunlight helps regulate your body’s natural rhythms. It signals the brain when to feel awake or sleepy. Without enough light, the brain can become confused. This can result in symptoms like sadness, tiredness, and social withdrawal.
The Role of Serotonin and Melatonin
Serotonin is a chemical in the brain that affects mood, appetite, and sleep. Lower levels of serotonin are linked to feelings of depression.
Melatonin is another brain chemical that regulates sleep. When it gets dark earlier in the day, your body may produce too much melatonin, making you feel sleepy all the time.
Who Is Most Likely to Experience SAD?
Anyone can experience SAD, but some groups are more at risk than others.
Risk Factors for SAD
- People living far from the equator

Self-Assessment Tests for SAD
If you think you might have SAD, you can start by taking a simple self-test. These are not a replacement for professional diagnosis, but they can help you decide if you need to see a doctor.
Simple SAD Questionnaire
Answer the following questions with “Yes” or “No”:
- Do you feel more tired or low-energy during certain months of the year?
- Do you lose interest in things you usually enjoy during the winter or summer?
- Do you eat more (especially carbs) or gain weight during the winter?
- Do you sleep more than usual during the winter months?
- Do your symptoms return every year at the same time?
If you answered “Yes” to three or more, it might be time to speak with a mental health professional.
How Is Seasonal Affective Disorder Diagnosed?
Only a licensed mental health professional or doctor can diagnose SAD. They will look at your symptoms, medical history, and seasonal patterns.
Diagnostic Criteria
According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), SAD is diagnosed as a type of major depressive disorder with a seasonal pattern.
Professional Treatment Options
The good news is that SAD is treatable. Several options can help, and many people feel better with the right care.
1. Light Therapy
Light therapy is often the first treatment for SAD. It involves sitting near a special light box that mimics natural sunlight. Most people use it for about 20–30 minutes every morning during the fall and winter months.
Important: Always talk to a doctor before starting light therapy, especially if you have eye conditions or bipolar disorder.
2. Talk Therapy (Cognitive Behavioral Therapy)
Therapy is another effective treatment. Cognitive Behavioral Therapy (CBT) helps you change negative thoughts and behaviors. It can teach you how to manage your mood and cope with stress in healthier ways.
3. Medication
In some cases, antidepressants are recommended. These medicines help balance the brain chemicals that affect mood. Doctors often prescribe SSRIs (Selective Serotonin Reuptake Inhibitors).
Note: Medication should always be prescribed and monitored by a healthcare provider.
Simple Lifestyle Tips to Feel Better
Besides therapy and medication, there are many things you can do to support your mental health during tough seasons.
1. Get More Natural Light
Try to spend time outside every day, even when it’s cloudy. A short walk in the morning can help reset your body’s clock.
2. Stay Physically Active
Exercise boosts your mood. Aim for at least 30 minutes of movement a day. Walking, yoga, dancing, and swimming are great options.
3. Keep a Regular Sleep Schedule
Go to bed and wake up at the same time every day. Avoid long naps, and try to get 7–9 hours of sleep each night.
4. Eat Healthy Foods
What you eat affects how you feel. Choose more fruits, vegetables, whole grains, and lean proteins. Avoid too much sugar and caffeine.
5. Stay Connected
Isolation can make SAD worse. Try to spend time with friends and family. Even a phone call can make a difference.
6. Practice Relaxation Techniques
Try deep breathing, meditation, or gentle stretching. These help reduce stress and bring more calm to your day.
When to Seek Professional Help
If your symptoms last more than two weeks or interfere with your life, it’s time to talk to a professional. Don’t wait until it gets worse. Help is available, and you don’t have to go through this alone.
What to Expect From a Mental Health Visit
They may ask about your symptoms, how long they’ve lasted, and how they affect your life. You might also fill out a short questionnaire. Based on this, they’ll suggest a treatment plan.
Resources and Support Groups
You are not alone. Many people deal with SAD. Talking to others who understand can make a big difference.
Where to Find Help
- National Institute of Mental Health
- Psychology Today – Find a Therapist
