The surprising connection between Red Light Therapy and better sleep.
If you've ever had a night where you tossed and turned, stared at the ceiling, or woke up feeling like you barely slept, you're not alone.
Quality sleep affects nearly every aspect of our health, from energy levels and mood to exercise recovery, immune function, and mental clarity. While most of us know the basics of good sleep hygiene (put your phone away, keep your room cool, avoid late-night caffeine), many people are looking for additional, drug-free ways to improve their sleep.
One option that's gaining attention is red light therapy.
Can simply spending 20 minutes under red and near-infrared light really help you sleep more deeply?
The answer is promising, but nuanced. Here's what the science says:
How Does Red Light Therapy Affect Sleep?
Unlike blue light from phones and tablets, well known to suppress melatonin production, red light behaves very differently.
Red and near-infrared wavelengths don't appear to interfere with your body's natural sleep signals the way blue light does. Researchers believe red light may instead support the body's natural recovery processes, reduce inflammation, promote relaxation, and in some cases even influence melatonin production.
Scientists are still working to understand exactly how these mechanisms interact, but one theory centers around the mitochondria, the tiny energy-producing structures inside every cell.
When red and near-infrared light are absorbed by the mitochondria, cells may produce energy more efficiently. This can support normal tissue repair, reduce oxidative stress, and help your body recover from the physical and mental demands of the day.
For many people, better recovery leads to better sleep.
The Research: Red Light Therapy and Sleep Quality
Researchers divided the athletes into two groups. One group received 30 minutes of whole-body red light therapy every evening for 14 days, while the other received a placebo treatment.
At the end of the study, the red light group demonstrated:
Improved overall sleep quality
Higher morning melatonin levels
Better endurance performance during exercise
Researchers also found that athletes whose melatonin increased the most experienced the greatest improvements in sleep quality. While this was a relatively small study in a very specific population, it provided encouraging early evidence that evening red light therapy may support more restorative sleep.
Better Recovery Often Means Better Sleep
Sleep and recovery go hand in hand. If you've ever had sore muscles after a hard workout, you know how uncomfortable recovery can sometimes feel. The same is true for physical stress from long workdays, parenting, travel, or simply everyday life.
Red light therapy has been widely studied for its ability to:
Support muscle recovery
Increase local circulation
Temporarily relieve minor muscle and joint aches and pains
Promote relaxation
When your body feels better, falling asleep, and staying asleep, often becomes easier. Many Barre West members enjoy pairing a barre class with a red light therapy session as part of their recovery routine before heading home for the evening.
Does Red Light Therapy Increase Melatonin?
This is where the research gets especially interesting. Melatonin is the hormone your body naturally produces as it prepares for sleep.Unlike bright blue or white light, which can suppress melatonin when you're exposed to it late in the evening, red light does not appear to have this same disruptive effect.
In the athlete study, researchers observed higher circulating melatonin levels following two weeks of evening red light therapy.
However, it's important to note that scientists still don't fully understand whether red light directly stimulates melatonin production or whether improved recovery and reduced physiological stress simply allow the body's natural sleep processes to function more efficiently.
Red Light Therapy Isn't a Sleeping Pill
One of the biggest misconceptions is that you'll climb into a red light therapy bed and immediately feel sleepy. That's usually not how it works. Instead, many people describe feeling:
More relaxed
Less physically tense
Mentally calmer
Better recovered after workouts
More prepared for sleep later that evening
Think of red light therapy as something that helps create the conditions for better sleep, not something that forces your body to fall asleep.
Why We Use LightStim at Barre West
At Barre West, we use the FDA-cleared LightStim ProPanel and LED Pro Bed, which deliver clinically researched red and near-infrared wavelengths through professional-grade LED technology. Unlike tanning beds, LightStim devices do not emit ultraviolet (UV) light, meaning there's no tanning and no UV exposure.
The LightStim system combines multiple wavelengths, including 630 nm, 660 nm, 855 nm, and 940 nm, to support healthy skin, circulation, muscle recovery, and overall wellness. Many clients choose to schedule a session in the evening as part of a relaxing bedtime routine or after a workout to support recovery before sleep.
Creating the Perfect Evening Routine
While red light therapy can be a valuable addition to your wellness routine, it works best alongside healthy sleep habits. For the best chance of improving your sleep, consider pairing red light therapy with:
Consistent bedtimes
Limiting screen time before bed
Keeping your bedroom cool and dark
Regular exercise
Mindful breathing or meditation
Limiting caffeine later in the day
Think of red light therapy as one piece of a larger sleep-support strategy.
The Bottom Line
The research on red light therapy and sleep is still evolving, but early studies are encouraging.
Current evidence suggests that evening red light therapy may improve subjective sleep quality, support recovery, and may even influence melatonin levels in some individuals. At the same time, larger studies in broader populations are still needed before researchers can make stronger recommendations.
If you're looking for a non-invasive, relaxing addition to your wellness routine, red light therapy may be worth exploring. Especially if your sleep challenges are related to stress, muscle soreness, or recovery from an active lifestyle.
At Barre West, we believe that great sleep is one of the foundationss one of the foundations of good health. Whether you're coming in after a workout or simply carving out quiet time for yourself, our LightStim ProPanel and LED Bed are designed to help you relax, recover, and support your body's natural rhythms.
