Discover how Dreaming of Light Therapy mimics sunset hues and natural red light to boost melatonin, regulate circadian rhythms, and help children sleep peacefully without blue light disruption.
Light therapy is useful for more than one condition; it can serve as a broad health and wellness tool. By supporting mitochondria, it may improve cell activity in targeted areas and help with skin concerns such as acne, wrinkles, and eczema.
Light therapy is also being studied for sleep. Sleep disorders are increasingly common, and even people without a diagnosed disorder often report un-refreshing sleep. Daily stress, anxiety, and evening screen use can disrupt normal sleep patterns, yet restorative sleep remains central to overall health.
While there are many kinds of sleep disorders—including insomnia, sleep apnea, restless legs syndrome, and narcolepsy—bright-light therapy has shown promise for some of these conditions. Research is also exploring its role in Parkinson’s disease-related sleep disruption.
Sleep-onset insomnia, the difficulty of falling asleep at a conventional hour, can be linked to mis-timed circadian rhythms. Light therapy may help shift these rhythms earlier or later, depending on the timing of exposure.
In advanced sleep phase disorder, evening sleepiness arrives between 6 p.m. and 9 p.m., leading to very early wake times. Evening light sessions can delay the body clock and push bedtime later.
Delayed sleep phase disorder keeps people awake well past midnight, with late wake-up times that shorten the day. Morning light therapy, used shortly after waking, can advance the internal clock and encourage earlier evening sleepiness.
A 2012 study of elite female basketball players found that 14 consecutive nights of 14–30 min light-therapy sessions acted as a non-pharmacological way to improve sleep quality. Participants also showed higher evening melatonin levels and reported better endurance performance.
Later work, including a 2013 Taiwanese study that recorded electroencephalography before, during, and after light exposure, suggested that light therapy can be beneficial for people with certain sleep disorders, although more research is needed.

A study on cognitive function in people with traumatic brain injury found that light therapy may support cognitive performance. Participants also reported fewer post-traumatic stress disorder (PTSD) episodes and improved sleep.
Recent University of Arizona Health Sciences work suggests that green-light therapy may improve sleep and possibly reduce migraine frequency; subjects reported fewer headaches and more restful nights.
The pandemic has added new stressors, and many people notice more disturbed sleep and vivid, unsettling dreams. Experts note that pandemic-related bad dreams are increasingly common.
Early evidence indicates that properly timed light therapy may help some users fall asleep faster, stay asleep longer, and wake feeling more refreshed. By gently reinforcing natural circadian cues, light treatment might also ease daily tension that feeds stress-related dreams.
