Is there light at the end of the dark tunnel of depression?
a Report issued by the Centers for Disease Control and Prevention Last year, it was revealed that nearly one in five adults in the United States has been diagnosed with depression.
Doctors commonly prescribe antidepressants, but these drugs can cause alarming skin conditions and “emotional dulling,” where the drugs numb all sensations, including joy, not just during hard times. It comes with a huge list of possible side effects.
But experts now say a drug-free solution to depression could be as simple as flipping a switch.
It is well established that light exposure affects human mood and cognitive function. A recent study that found a 40% remission rate for non-seasonal depression in patients treated with Bright Light Therapy (BLT) proves this point.
supported by research from National Institutes of Health The study found that patients with seasonal affective disorder achieved symptom remission when they received bright light therapy over a four-week period, and the researchers found that the same therapy could be used in non-seasonal depressive disorder. I was interested in how it could be used to alleviate symptoms in those who suffer.
Published in JAMA PsychiatryThe study featured data from 858 participants diagnosed with depression.
These patients were instructed to sit in front of a fluorescent light box that emitted bright white light at an intensity of 10,000 lux for at least 30 minutes each day.
The research team observed that the remission rate in patients treated with BLT (40%) was significantly higher than in the control group treated with antidepressants alone (23%).
The research team said, “These findings suggest that bright light therapy is an effective adjunctive treatment for non-seasonal depressive disorder, and that adding bright light therapy can improve initial treatment. “This suggests that reaction times may be improved.”
Researchers argue that BLT has the potential to be an accessible and cost-effective supplement or alternative to antidepressants, potentially offering a ray of hope to people suffering from depression. are.
“While the cost of outpatient treatment with antidepressants varies widely, exposure to external light generally has no cost or limit. For this reason, bright light therapy is an effective adjunct treatment for non-seasonal depressive disorder. “This reinforces the need to establish a
Since 2005, American Psychiatric Association recommends BLT As a treatment option for patients with major depressive disorder.
How does light exposure affect mood and cognition?
According to forbesWhen humans are exposed to bright light, the light enters the retina. Activated neurons known as retinal ganglion cells.
These neurons transmit information between the retina and the brain and are directly involved in regulating mood.
This latest study adds to the growing body of evidence linking BLT to improved mental health; Experts warn home treatment is dangerous Also, commercially available light boxes may not be as effective as light boxes used by medical professionals. For best results, consult your provider to determine the appropriate light intensity and duration.
