Light Therapy for Seasonal Affective Disorder: How to Bring the Sun Indoors
As the days grow shorter, your body feels the shift—even if you try to power through. For many people, especially Black women balancing multiple roles, reduced sunlight can trigger Seasonal Affective Disorder (SAD). One powerful way to reset your body's rhythm is through light therapy.
("Not sure if what you're feeling is SAD? Start with our guide on Recognizing and Managing Seasonal Affective Disorder.")
What Is Light Therapy?
Light therapy uses a special lamp that mimics natural sunlight to regulate mood, energy, and sleep patterns. When winter arrives and daylight hours shrink, your brain produces less serotonin—the neurotransmitter responsible for mood regulation—while increasing melatonin production, which makes you feel sleepy and sluggish.
Light therapy boxes emit bright light that signals your brain to reduce melatonin production and boost serotonin levels, effectively resetting your circadian rhythm.
This treatment has been extensively researched and is considered a first-line intervention for SAD by mental health professionals.
The therapy works by delivering light that's significantly brighter than typical indoor lighting—usually around 10,000 lux compared to standard room lighting of about 100-300 lux.
The Science Behind the Light
Your body's internal clock, or circadian rhythm, is heavily influenced by light exposure. During shorter winter days, this natural rhythm gets disrupted, leading to the symptoms of SAD: fatigue, mood changes, difficulty concentrating, and changes in appetite or sleep patterns.
Light therapy helps restore balance by providing your brain with the light cues it needs to maintain healthy hormone production and sleep-wake cycles.
Research shows that light therapy can be as effective as antidepressant medications for treating seasonal depression, with the added benefit of minimal side effects and relatively quick results—many people notice improvements within one to two weeks of consistent use.
How to Use Light Therapy Effectively
Timing is everything. Use your light therapy box within the first hour of waking up, ideally between 6 AM and 8 AM. This morning timing helps regulate your circadian rhythm most effectively. Avoid using the device late in the day, as it can interfere with your ability to fall asleep at night.
Create a routine. Place the lamp on your desk during morning routines—while drinking coffee, checking emails, or reading. The key is consistency; use it at the same time each day for maximum benefit.
You don't need to stare directly at the light; having it in your peripheral vision while you go about your morning activities is sufficient.
Choose the right device. Look for a UV-free device with at least 10,000 lux of light intensity. The lamp should be positioned about 16-24 inches from your face, depending on the manufacturer's instructions.
Smaller, less intense lights require you to sit closer and use them longer.
Start gradually. Begin with 15-minute sessions and gradually increase to 20-30 minutes as your eyes adjust to the bright light. Some people experience mild headaches or eye strain initially, but these symptoms typically subside within a few days.
Why It Matters for Black Women
The intersection of being Black and female creates unique mental health challenges that are often overlooked. Systemic racism, cultural expectations of strength, and the pressure to excel professionally while managing family responsibilities can amplify the effects of seasonal depression.
Too often, Black women are expected to "push through" depression or fatigue without tools or support, leading to burnout and emotional exhaustion.
Light therapy offers a tangible, accessible way to prioritize wellness without requiring significant time investment or major lifestyle changes. It's a form of self-care that can be incorporated into existing routines, making it particularly valuable for women juggling multiple responsibilities.
Additionally, there's evidence suggesting that people with darker skin may be at higher risk for vitamin D deficiency during winter months, which can compound mood-related symptoms.
While light therapy doesn't replace vitamin D supplementation, it addresses the circadian rhythm disruption that contributes to seasonal mood changes.
Making It Work for Your Life
Consider investing in a portable light therapy device if you travel frequently or want flexibility in where you use it. Some people find desk lamps more convenient than larger boxes, while others prefer wearing light therapy glasses during their morning commute.
Track your mood and energy levels in a journal to monitor your progress. Note any changes in sleep quality, motivation, or overall well-being. This information can be valuable if you're also working with a therapist or healthcare provider.
Light therapy isn't a cure-all, but it's a powerful first step in reclaiming your energy during darker months. By giving your body the light it craves, you're taking an active role in maintaining your mental health and honoring your need for wellness—even when the world expects you to simply endure.
Remember: prioritizing your mental health isn't selfish; it's essential. Light therapy offers a scientifically-backed way to support your well-being during the challenging winter months, helping you show up as your best self for all the important people and responsibilities in your life.
