When to Stop Using SAD Light?
Symptom Improvement
You might notice your mood lifting after using your SAD Light for a few days or weeks. Many people feel better quickly, sometimes even after just one session. Here’s a quick look at how fast some studies found people improved:
|
Study |
Findings |
Duration of Light Therapy |
|---|---|---|
|
Sher et al. (2001) |
Significant improvement in SAD scores after 1 hour |
1 hour |
|
Virk et al. (2009) |

20-40 minutes |
|
Goel and Etwaroo (2006) |

If you feel your energy coming back and your mood stays steady for a few weeks, that’s a good sign. You may be ready to think about stopping your SAD Light soon. Keep track of how you feel each day. If your symptoms return, you can always start using your light again.
Seasonal Changes
Most people use their SAD Light from early fall until spring. As the days get longer and you see more sunlight, your body starts to adjust. Seasonal Affective Disorder usually follows a pattern. Symptoms show up in autumn and winter, then fade away in spring or summer. This means you can often stop using your light when natural daylight increases.
-
Use your SAD Light from early fall until spring.
-
Keep using it until you notice more daylight outside.
-
If you stop too soon, your symptoms might come back.
Tip: Try going outside in the morning as spring arrives. Natural sunlight helps your body wake up and feel better.
Mood Stability
You want your mood to stay steady before you stop using your SAD Light. Doctors often use special scores to measure mood changes. If your mood stays strong for two weeks in a row, you’re probably ready to stop.
|
Measurement Method |
Threshold for Discontinuation |
|---|---|
|
SIGH-SAD Scores |
Increase of 12 points or more over pre-treatment score for 2 consecutive or nonconsecutive weeks |
You can pause your SAD Light for a day or two to see how you feel. If your mood drops or you feel tired again, start using your light right away. Most people find that stopping for a short time is safe, but symptoms can return after a few days.

Medical Advice
Doctor Recommendations
You should talk to your doctor before changing your SAD Light routine. Your doctor knows your health history. They can help you decide when to stop or change your therapy. If you take antidepressants, checking with your doctor is even more important. Stopping light therapy too soon can make your symptoms come back. Your doctor can help you notice these changes. They will guide you on what to do next.
-
Talk to your doctor before changing light therapy, especially if you take medicine.
-
Ask your doctor if your light box is good for your symptoms.
-
Sometimes, patients and doctors are not sure when to stop using a SAD Light. It is normal to have questions.
Tip: Always read the instructions that come with your light box. The manufacturer’s guide can tell you if your device is safe and works for SAD.
Special Considerations (e.g., Bipolar Disorder)
If you have bipolar disorder, you need to be extra careful with light therapy. Light therapy can help with depression. But sometimes it can cause manic symptoms. Doctors often suggest a special plan for people with bipolar disorder. You might use the light around midday, between 12:00 PM and 2:30 PM. Start with 15 minutes. Add 15 minutes each week until you reach one hour per day.
-
Begin with 15 minutes of light at midday.
-
Add 15 minutes each week, up to one hour.
-
If you notice signs of mania, like feeling too energetic or not needing sleep, call your treatment team right away. Cut back on your light time.
The risk of switching to mania during light therapy is very low - less than 1%. The chance of switching to hypomania is a little higher, but still rare. These rates are even lower than with placebo treatments. Doctors in the Netherlands use a special plan to keep you safe and make sure the therapy works well.
Note: If you have bipolar disorder, always follow your doctor’s advice about using a SAD Light. Never change your routine without talking to your care team.
Discontinuing SAD Light
Gradual Reduction
You might feel ready to stop using your SAD Light as spring arrives or your mood stays steady. Instead of quitting all at once, try cutting back slowly. Use your light every other day for a week. If you still feel good, drop to two or three times a week. This gentle approach helps your body adjust. If you notice your mood slipping, you can always go back to daily use for a while. Some people find that tapering off makes the change easier and lowers the chance of symptoms returning.
Tip: Keep a simple journal. Write down how you feel each day as you reduce your light sessions. This helps you spot changes early.
Monitoring Symptoms
Pay close attention to your mood and energy as you cut back. Watch for signs like feeling tired, sad, or losing interest in things you enjoy. If these symptoms come back, start using your SAD Light again. You do not have to wait for things to get worse. Early action can help you feel better faster. If you feel unsure, talk to your doctor. They can help you decide what to do next.
-
Notice changes in sleep, appetite, or mood.
-
Ask family or friends if they see changes in you.
-
Do not ignore small warning signs.
Adjusting Routine

-
Wake up and go to bed at the same time every day.
-
Get outside in the morning for natural sunlight.
-
Eat meals at regular times.
-
Avoid caffeine and screens before bedtime.
-
Make time for hobbies or relaxing activities.
These habits support your body’s natural clock and help you feel your best. If symptoms return, you can always restart your light therapy or talk to your healthcare provider about other options.
After Stopping SAD Light

Possible Symptom Return
You might feel great after you stop using your SAD Light. Sometimes, though, symptoms can sneak back after a few days or weeks. You may notice your mood dropping, feeling tired, or losing interest in things you enjoy. This is normal for many people. In fact, studies show that only about 41% of people keep using light therapy regularly after their first treatment. Even fewer use it enough to get the full benefit. If you start to feel low again, you are not alone.
Tip: Keep track of your mood for a few weeks after you stop. A simple mood journal can help you spot changes early.
Next Steps
If your symptoms return, you have options. You can start using your SAD Light again, just like before. Most people use it for 30 minutes in the morning with a 10,000 lux light box. You can also talk to your doctor about other treatments. Some people try antidepressants like SSRIs or bupropion. Others find that getting outside for natural sunlight or making small lifestyle changes helps a lot.
Here are some steps you can take if your symptoms come back:
-
Restart your light therapy in the morning.
-
Ask your healthcare provider about medicine or therapy.
-
Try to spend more time outdoors, especially in the morning.
