Everything You Need to Know About Using a Home Light Box
If you’ve found yourself searching for “home light box,” you’re likely wondering how these light therapy devices work and whether one would benefit you. As winter brings shorter days with less natural sunlight, many people struggle with low mood, fatigue, and lack of motivation—all symptoms commonly referred to as the “winter blues” or seasonal affective disorder (SAD). A light box is a treatment option designed to mimic the effects of natural sunlight and help regulate your body’s internal clock.
How Do Light Boxes Work?
Light boxes emit very bright light that is similar to natural sunlight. The intensity is around 10,000 lux, which is significantly brighter than typical indoor lighting or sunlight on an overcast day. When this bright light enters your eyes, it triggers signals to your brain that help regulate hormones related to mood, energy levels, and your circadian rhythm. Specifically, light exposure stimulates the release of serotonin, a neurotransmitter that helps lift your mood, and suppresses the secretion of melatonin, the hormone that makes you feel tired and promotes sleep.
By optimizing your body’s production of serotonin and melatonin, light therapy aims to reduce winter blues symptoms like low mood, fatigue, anxiety, sleep problems, and cravings for carbohydrates. Most experts recommend using a light box for 30 minutes within 1 hour of waking up each morning. For best results, look directly into the light without squinting or looking away for the entire session.
Types of Light Boxes
There are a few different types of light boxes available:
- Desktop light boxes – Small and portable units intended for desk or tabletop use. These produce around 10,000 lux and are convenient to use at home or work.
- Floor light boxes – Larger units that stand on the floor close to eye level for a more natural viewing position. Floor models typically offer higher light intensities of around 10,000-20,000 lux.
- Light visors – Head-mounted devices that direct bright light up towards the eyes. Some find visors more comfortable than staring directly into a box.
No matter the style, look for a medical-grade light box or light therapy lamp with full-spectrum bulbs that produce both bright white light and broader UV/infrared light similar to sunlight. Additional features like a timer, adjustable light intensity, and an easy on/off switch make light boxes more user-friendly. Reputable brands include Verilux, Carex, Beurer, and Northern Light Technologies.
When Should I Use a Light Box?
Light therapy is most effective during specific seasons and times of the day:
- Winter months (September – April in the northern hemisphere) – This is when daylight hours diminish and SAD symptoms typically surface.
- Morning hours – Exposure to light first thing in the morning sets your body clock for the day and lifts mood before depressive thoughts and behaviors emerge.
- Non-sunny or overcast winter days – Even on brighter winter days, sunlight may not be intense enough to trigger the same therapeutic responses as a light box.
Some research indicates that using a light box 30-45 minutes each morning, 5-7 days per week provides adequate treatment duration to observe improvements in mood, energy levels, sleep quality, and appetite. However, you may only need to use it for 15-30 minutes once SAD symptoms dissipate in spring.
Potential Benefits of Light Therapy
Numerous clinical studies show light boxes can effectively treat SAD symptoms for many who use them as directed. Some potential benefits include:
- Reduced sad or depressed mood
- Increased motivation and energy levels
- Better quality of sleep
- Improved appetite and weight maintenance
- Reduced anxiety and irritability
- Regulated circadian rhythms and melatonin/serotonin production
While results vary between individuals, light therapy is considered a very safe treatment option with minimal side effects like eye strain. It provides an alternative to antidepressant medications and allows you to independently manage your SAD symptoms each winter season.
Tips From My Experience with Light Therapy
Here are a few tips I’ve picked up from using a light box successfully for the past 3 winters:
- Be consistent – Shoot for using it around the same time daily to establish a regular light-dark cycle.
- Slowly work up duration – Don’t overdo it at first by sitting too close or for too long to avoid eyestrain.
- Combine with other activities – Read, eat breakfast, or do light chores facing the light box.
- Track your progress – Note changes in mood, symptoms, and energy levels to evaluate benefits.
- Adjust settings as needed – You may require different duration, times of use, or light intensity each season.
- Consider a travel light box – A portable version helps if you work somewhere without windows or have to travel during winter.
Light therapy takes consistency and a bit of trial and error to figure out your individual needs. But it’s basically free after the initial light box purchase and can keep SAD symptoms at bay each winter without medications. That’s pretty amazing if you ask me!
Potential Downsides of Light Therapy
While light boxes are quite safe, a few minor downsides to be aware of include:
- Eye strain – Bright light can sometimes cause temporary eyestrain, redness, or headaches, especially if you have sensitive eyes.
- Discomfort looking at the light – Avoidance behaviors may undermine therapeutic effects.
- Mild skin irritation – Some report mild sunburn-like sensations on face from full-spectrum bulbs.
- Inadequate response – A minority may still require medication or additional counseling for severe symptoms.
- Cost – Light boxes range from $50-300 depending on size and features. In the long run though, it’s cheaper than meds.
Overall, the risks are quite low compared to lifestyle improvements and symptom relief achievable from consistent light therapy use. And most side effects cease once the session ends.
When Should I Consider Medical Advice?
While light boxes are very safe as standalone treatment for mild-moderate SAD, it’s a good idea to consult your doctor if:
- Symptoms are severe or include psychosis, mania, or suicidal thinking
- You have eye conditions like macular degeneration or retina damage
- You take medications that increase photosensitivity
- Symptoms persist or worsen after adequate light therapy trials
- You experience concerning side effects from light exposure
In some cases, antidepressents, psychotherapy, or specialized light boxes may provide better outcomes. Your medical provider can help evaluate severity and tailor the safest and most effective treatment plan for your individual needs.
