Seasonal Affective Disorder

As the leaves turn and the days shorten across Western Pennsylvania and West Virginia, many people look forward to sweaters, football, and the holidays. For others, the same change brings a heaviness that is hard to explain: mornings feel impossible, favorite activities lose their spark, and it seems easier to pull away from everyone. If that happens to you around the same time each year, you may be dealing with seasonal affective disorder (SAD). It is real, it is common, and it is treatable.

What is seasonal affective disorder?

Seasonal affective disorder is a form of depression marked by a recurring seasonal pattern. According to the National Institute of Mental Health (NIMH), symptoms typically last about four to five months of the year. The most common form is winter-pattern SAD, which begins in late fall or early winter and eases in spring and summer. A less common summer pattern also exists.

SAD is more than “not liking winter.” To be diagnosed, depressive episodes must recur during the same season for at least two consecutive years and occur noticeably more often then than at other times of the year. Only a licensed medical or mental health professional can make that diagnosis, but knowing the pattern can help you put words to what you are feeling.

Signs and symptoms of SAD

SAD shares the core symptoms of depression, including a persistent sad, anxious, or “empty” mood for at least two weeks, hopelessness, irritability, guilt, loss of interest in activities you used to enjoy, fatigue, trouble concentrating, and changes in sleep or appetite. Winter-pattern SAD often adds a few distinctive signs:

Why it happens and who is at risk

Researchers do not know the exact cause of SAD, but reduced sunlight in fall and winter appears to play a central role. Mayo Clinic describes three likely contributors:

• Your internal clock. Less daylight can disrupt your circadian rhythm, leaving you feeling out of sync.
• Serotonin. Reduced sunlight may lower serotonin, a brain chemical that affects mood.
• Melatonin. Seasonal changes can shift melatonin levels, which affect sleep and mood.

SAD is diagnosed more often in women and younger adults. Risk is also higher for people who live farther from the equator (shorter winter days are a reality here in the Mid-Atlantic), people with a family history of depression, people living with major depression or bipolar disorder, and people with low vitamin D levels.

Winter blues or SAD?

Almost everyone has a few gray days in January. The difference is in how long, how strong, and how disruptive the symptoms are. The “winter blues” are mild and pass quickly. SAD lasts for weeks, returns year after year, and makes it hard to work, parent, stay connected, or care for yourself. If you are not sure which you are experiencing, a counselor can help you sort it out without judgment.

Treatments that work

The encouraging news is that SAD responds well to treatment, and many people use more than one approach:

Light therapy

Light therapy uses a special light box, typically 10,000 lux, that filters out UV rays. NIMH notes it is usually used for 30 to 45 minutes each morning from fall into spring. Check with your doctor before starting, especially if you have an eye condition or take medications that increase light sensitivity.

Cognitive behavioral therapy for SAD (CBT-SAD)

CBT-SAD helps you notice and challenge the discouraging thoughts that tend to surface in winter (“I can’t do anything until spring”) and uses behavioral activation, scheduling meaningful and enjoyable activities even when motivation is low. According to NIMH, CBT-SAD works about as well as light therapy, and one long-term study found its benefits lasted longer.

Medication

Some people benefit from antidepressants prescribed by a physician or psychiatric provider. Your counselor can coordinate with your medical team and help you process questions or feelings about medication.

Vitamin D

Vitamin D supplements may help some people, though research results are mixed. Ask your provider before starting any supplement.

Everyday steps that help

• Get morning light. Open blinds as soon as you wake and step outside for even 10 minutes during daylight hours.
• Keep a steady rhythm. Wake, eat, and go to bed at consistent times, even on weekends.
• Move your body. A brisk walk, especially outdoors at midday, can lift energy and mood.
• Plan small joys. Put enjoyable, connecting activities on your calendar before symptoms start, not after.
• Stay connected. Say yes to small group, coffee with a friend, or a phone call, even when you would rather stay in.
• Start early. If SAD returns each year, talk with your counselor or doctor in early fall about a plan to begin before symptoms peak.

Faith in a dark season

Scripture reminds us that “for everything there is a season” (Ecclesiastes 3:1). Winters, literal and spiritual, are part of life, and they do not mean God has left you. The psalmists were honest about despair and still reached for hope, often in the same breath. Struggling with depression is not a sign of weak faith. It is a health concern that deserves care, just like any other.

Many Christians find that small, steady spiritual practices help during SAD season: a short morning Scripture reading paired with light therapy, praying with a trusted friend, worship music on a winter walk, or simply telling God the truth about how you feel. Faith and good clinical care work together.

Frequently asked questions about SAD

When does seasonal affective disorder usually start?

Winter-pattern SAD typically begins in late fall or early winter and improves in spring and summer. Symptoms usually last about four to five months.

Is SAD the same as depression?

SAD is a type of depression with a seasonal pattern. It shares core depression symptoms and often adds oversleeping, carbohydrate cravings, and social withdrawal in winter.

Does light therapy really work?

Light therapy is one of the main treatments for winter-pattern SAD. It usually involves sitting near a 10,000-lux light box for 30 to 45 minutes each morning. Talk with your doctor before starting.

Can counseling help with seasonal depression?

Yes. Cognitive behavioral therapy adapted for SAD has been shown to work about as well as light therapy, and its benefits may last longer. A counselor can also help you plan ahead for future seasons.

Is it wrong for a Christian to struggle with depression?
