Does Bright Light Therapy Help Hospitalized Teens with Severe Depression?
A randomized clinical trial published in JAMA Psychiatry examined whether the effects of adolescent psychiatric inpatient treatment as usual for major depressive disorder can be enhanced by simultaneous use of morning bright light therapy. This study of 224 adolescents found that 4-week inpatient treatment as usual augmented by bright light therapy was not superior to treatment as usual plus placebo red light. Both groups showed significant reductions in depressive symptoms, and there were no serious adverse events during the trial caused by light-related interventions.
Dr. Kumar’s Take
This JAMA Psychiatry study addresses an important question about enhancing treatment for severely depressed adolescents who require hospitalization. While the results show that bright light therapy didn’t provide additional benefits beyond standard inpatient care, this is still valuable information. It tells us that the comprehensive inpatient treatment these teens receive is already quite effective, with both groups showing significant improvement. The safety data is reassuring - no serious adverse events from light therapy means it’s a safe intervention to try. For teens with severe depression, we need every tool available, and while light therapy may not be a game-changer in the inpatient setting, it might still have value in outpatient or maintenance treatment.
Study Snapshot
This randomized clinical trial enrolled 224 adolescents with moderate to severe depression receiving inpatient psychiatric treatment. Participants were randomly assigned to receive either bright light therapy or placebo red light as an add-on to their standard inpatient treatment over a 4-week period. The study measured depressive symptoms and safety outcomes to determine whether bright light therapy could enhance the effectiveness of comprehensive inpatient psychiatric care.
Results in Real Numbers
The trial found that 4-week inpatient treatment as usual augmented by bright light therapy was not superior to treatment as usual plus placebo red light in reducing depressive symptoms. Both groups showed significant reductions in depressive symptoms over the 4-week treatment period, indicating that the standard inpatient treatment was effective for both groups.
Importantly, there were no serious adverse events during the trial caused by light-related interventions, demonstrating that bright light therapy is safe for use in adolescents with severe depression. The lack of additional benefit from bright light therapy suggests that the comprehensive nature of inpatient psychiatric treatment may already address the circadian and mood regulation mechanisms that light therapy typically targets.
The significant improvements seen in both groups highlight the effectiveness of intensive inpatient treatment for adolescents with moderate to severe depression, regardless of the addition of light therapy.
Who Benefits Most
While this study didn’t show additional benefits from bright light therapy in the inpatient setting, adolescents with depression who have prominent circadian rhythm disturbances or seasonal patterns might still benefit from light therapy in other treatment contexts. The safety profile supports its consideration as a low-risk intervention.
Teens with depression who are receiving outpatient treatment or those in maintenance phases after inpatient care might find light therapy more beneficial than those receiving intensive inpatient interventions. The intervention may be particularly relevant for adolescents with delayed sleep phase or other circadian rhythm disorders commonly seen in this age group.
Safety, Limits, and Caveats
The study demonstrated that bright light therapy is safe for adolescents with severe depression, with no serious adverse events related to the light interventions. However, the lack of additional benefit in the inpatient setting suggests that light therapy may not be necessary when comprehensive psychiatric treatment is already being provided.
The study was conducted in an inpatient setting where patients receive intensive, multimodal treatment, which may have masked potential benefits of light therapy that might be more apparent in less intensive treatment settings. Individual responses to light therapy may vary, and some adolescents might still benefit even when group-level effects are not significant.
Practical Takeaways
- Understand that bright light therapy is safe for adolescents with depression, even in severe cases requiring hospitalization
- Recognize that comprehensive inpatient treatment is highly effective for teen depression, with significant improvements expected regardless of additional interventions
- Consider that light therapy may be more beneficial in outpatient settings or for specific circadian rhythm problems rather than as an add-on to intensive inpatient care
- Discuss light therapy options with healthcare providers, particularly for teens with sleep-wake cycle disturbances or seasonal depression patterns
- Focus on the comprehensive treatment approach rather than expecting single interventions to provide dramatic additional benefits in severe depression
What This Means for Adolescent Mental Health
This study provides important safety data for bright light therapy in adolescents and demonstrates the effectiveness of comprehensive inpatient treatment for severe teen depression. While light therapy didn’t provide additional benefits in this intensive treatment setting, it remains a safe option for consideration in other contexts.
The research also highlights that adolescents with severe depression can achieve significant improvement with appropriate intensive treatment, providing hope for families facing these challenging situations.

FAQs
Is bright light therapy safe for teenagers with depression?
Yes, this study demonstrated that bright light therapy is safe for adolescents with severe depression, with no serious adverse events related to the light interventions.
Why didn’t bright light therapy help in this study?
The comprehensive nature of inpatient psychiatric treatment may already address the mechanisms that light therapy typically targets, making additional benefits difficult to detect.
Should teens with depression still try light therapy?
While it didn’t provide additional benefits in intensive inpatient settings, light therapy may still be valuable for outpatient treatment or specific circadian rhythm issues in adolescents.
Bottom Line
Bright light therapy is safe for adolescents with severe depression but didn’t provide additional benefits beyond comprehensive inpatient psychiatric treatment. This highlights the effectiveness of intensive treatment while providing safety data for light therapy use in teens with depression.
