How to Combat Seasonal Depression

Back to Thea Times

When the days get shorter and the sunlight disappears before dinner, it’s normal to feel your mood dip. Many students experience what’s commonly known as seasonal depression or Seasonal Affective Disorder (SAD), a type of depression linked to seasonal changes, especially in late fall and winter. 

But the good news is this: there are practical, evidence-supported ways to manage seasonal depression and protect your mental health during darker months. And even small actions can make a real difference in your daily mood, focus, and overall well-being. 

This guide breaks down the science behind seasonal depression, why students may feel it more intensely, and what you can do to start feeling better. 

What causes seasonal depression? 

Seasonal depression has been linked to several biological and environmental factors: 

1. Reduced sunlight exposure Less daylight disrupts your circadian rhythm, the internal clock that regulates sleep, energy levels, and mood. When this rhythm gets thrown off, motivation and focus often go with it. 

2. Changes in serotonin Serotonin, a neurotransmitter that stabilizes mood, tends to drop when sunlight decreases. Lower serotonin is associated with sadness, fatigue, irritability, and depression-like symptoms. 

3. Increased melatonin With more darkness, your brain produces more melatonin. This can make you feel tired earlier, struggle to wake up in the morning, and feel less alert throughout the day. 

4. Stress + academic pressure Midterms, finals, shorter days, and colder weather can create a mental “perfect storm.” For many students, winter is the hardest season to stay motivated and emotionally balanced. 

Signs you might be dealing with seasonal depression 

Seasonal depression looks different for everyone, but common symptoms include: 

• Low energy or persistent fatigue 

• Feeling sad, numb, or “disconnected” 

• Oversleeping or struggling to get out of bed 

• Cravings for carbs or comfort foods 

• Trouble concentrating or remembering information 

• Loss of interest in activities 

• Feeling overwhelmed more easily 

• Increased anxiety during colder months 

If these symptoms are affecting your daily life, it’s important to take them seriously and use strategies that help, not just temporary distractions. 

Science-backed ways to beat seasonal depression 

Below are the most effective, research-supported strategies to help you manage seasonal depression, especially when your schedule is packed with classes, studying, and finals. 

1. Get as much natural light as possible 

Natural sunlight has a powerful impact on mood. Even 10–20 minutes of morning sunlight can help regulate your circadian rhythm, boost alertness, and improve serotonin levels. 

Try: 

• Sitting near a window while studying 

• Going for a short walk between classes 

• Opening blinds immediately when you wake up 

• Moving your desk setup to the brightest part of your room 

If you live in an area with very little daylight, consider the next strategy. 

2. Try light therapy (it’s one of the most researched treatments) 

Light therapy lamps mimic natural sunlight and have been shown in multiple studies to reduce seasonal depression symptoms in as little as 1–2 weeks. 

Tips for using light therapy safely and effectively: 

• Look for a 10,000-lux lamp 

• Use it for 20–30 minutes in the morning 

• Sit about 16–24 inches away from the light 

• Keep it angled toward your face, not directly into your eyes 

Students often use light therapy while doing morning flashcards or reviewing notes; a simple habit with a big payoff. 

3. Keep a consistent sleep schedule 

Seasonal depression often disrupts sleep, but an irregular schedule can make symptoms even worse. 

Sleep researchers recommend: 

• Going to bed and waking up at the same time every day 

• Limiting naps to 20–30 minutes 

• Avoiding screens 30–60 minutes before bed 

• Getting sunlight within the first hour of waking up (huge circadian boost) 

Good sleep hygiene helps your emotional regulation, memory, and cognitive performance, all essential during heavy study seasons. 

4. Move your body, even lightly 

You don’t need a full workout plan to see benefits. Research shows that low-to-moderate physical activity helps increase serotonin, endorphins, and overall mood. 

Simple options that work: 

• A 10-minute walk 

• Stretching before you start studying 

• A quick YouTube workout 

• Light yoga or pilates in your room 

• Dancing to a few songs 

When you’re dealing with seasonal depression, aim for consistency, not intensity. 

5. Keep your academic load manageable 

Seasonal depression can make studying feel heavier than usual. Instead of pushing harder, try structuring your work in ways your brain can handle: 

• Break studying into short, manageable sessions 

• Prioritize active recall over rereading 

• Create a daily “must-do” list of 2–3 items 

• Use timers to prevent burnout 

• Study in bright, well-lit spaces 

If you use Thea, this is a great time to lean on study tools that reduce effort: 

• Run a Smart Study session when you don’t have the energy to plan 

• Use flashcards with spaced repetition for quick, effective reviews 

• Try games and bite-sized practice when you need lighter study methods 

• Use Study Kits to stay organized without extra work 

Little adjustments like these help prevent seasonal depression from turning academic stress into a bigger emotional burden. 

6. Social interaction matters more than you think 

When you're feeling low, isolating yourself feels easier... but it often makes seasonal depression worse. 

Try to: 

• Study with a friend, even silently 

• Join a campus club or attend student events 

• Call or text someone you trust 

• Do weekly “micro-hangouts” (coffee for 20 minutes, a walk, a study date) 

You don’t need long, energy-draining social outings. You just need small points of connection that remind your brain you’re not alone. 

7. Eat foods that support stable mood and energy 

Seasonal depression often triggers carb cravings, which can cause energy spikes and crashes. 

Instead, aim for steady, nourishing foods like: 

• Complex carbs (oatmeal, whole grains, sweet potatoes) 

• Healthy fats (nuts, seeds, avocado, olive oil) 

• Protein (eggs, yogurt, chicken, beans) 

• Omega-3–rich foods (salmon, walnuts, chia seeds) 

• Fruits + vegetables for micronutrients 

You don’t have to overhaul your whole diet. Even one balanced meal a day can help. 

8. Build tiny rituals that protect your mental health 

Rituals give your day structure, which is powerful when sunlight and motivation feel unpredictable. 

Try adding one or two of these daily “anchor habits”: 

• Make tea every morning 

• Do 5 minutes of journaling 

• Use a sunrise alarm clock 

• Read for pleasure before bed 

• Light a candle during your study session 

• Keep a gratitude or “good moments” list 

Tiny rituals can remind your brain of normalcy, comfort, and progress, all things that protect mental health during seasonal depression. 

9. Know when to ask for help 

If your symptoms last more than two weeks, are getting worse, or affect your ability to function, it’s important to reach out. 

You deserve support. Seasonal depression is common and treatable, and reaching out is a sign of strength, not weakness. 

Consider talking to: 

• A campus counselor 

• A therapist or doctor 

• A trusted adult, professor, or mentor 

If you ever feel hopeless or overwhelmed, please seek help immediately — you never have to navigate this alone. 

Final Thoughts: You’re not “just being dramatic,”  winter is hard 

Seasonal depression is real, and for many students, winter brings a mix of academic pressure, lack of sunlight, and emotional fatigue. Be patient with yourself, be consistent with small habits, and build routines that help your brain function even when motivation is low. 

And remember: you don’t need to beat seasonal depression with perfection. You just need enough consistency to support your mental health and keep going. Even one small step at a time! 

If you want to make studying easier during the winter slump, Thea can help you stay organized, stay focused, and get more done in less time—so you can spend more energy taking care of yourself.
