Benefits of Red Light Therapy for Sleep

If you’re tossing and turning at night, you’re not alone. Many people in Tucson struggle with poor sleep and look for natural ways to rest better. Red light therapy has become a popular option for improving sleep. But does gentle red light at night truly help you fall asleep faster or reset your internal clock? Here’s how red light therapy at Greentoes North might affect your sleep and circadian rhythm, including answers to common questions so you can decide if it’s right for you.

Does red light therapy improve sleep?

Red light therapy shows promise in improving sleep quality for many people. Although research is ongoing and limited, some small studies suggest red light exposure may help you sleep better and wake up feeling refreshed.

One study involving athletes found that 30-minute sessions of whole-body red light therapy each night led to better sleep and increased melatonin levels. Melatonin is the hormone your body naturally produces to signal sleep. Participants also felt more alert and less tired the next morning. This suggests red light at bedtime might help you fall asleep more easily and have more energy upon waking.

Early evidence and anecdotal experiences generally point toward improved sleep.

Red light therapy may help you sleep by:

• Increasing melatonin production naturally in the evening.
• Relaxing your body by gently warming your skin, promoting easier sleep.
• Reducing pain or discomfort at night by improving circulation and easing inflammation.
• Replacing sleep-disruptive blue light from screens or bright bulbs.

While individual results vary, adding red light therapy to your bedtime routine could help you sleep more soundly when combined with other healthy sleep habits.

Is red light therapy good before bedtime?

Red light therapy is generally beneficial before bedtime. Evening is the best time because red light is gentle on your eyes and does not signal your brain to stay awake, unlike blue or white lights from screens and devices.

Blue light tells your brain it’s daytime, suppressing melatonin production and making sleep harder. In contrast, red wavelengths don’t disrupt melatonin. Using red light therapy around 30 minutes before bed can help your brain recognize it’s nighttime, encouraging relaxation and sleepiness.

Additionally, red light therapy might increase serotonin, a hormone that stabilizes mood, and lower cortisol, a stress hormone that interferes with sleep. Many people find that sitting quietly with a red light device makes them feel calmer and more ready for bed.

For optimal results, dim other lights or turn them off completely during your red light session. You could read a book under soft red lighting instead of a traditional lamp, further minimizing disruptive blue light exposure. This method creates a calm environment that encourages your body to unwind and prepare for sleep naturally.

Can red light therapy reset the circadian rhythm?

Your circadian rhythm is your internal clock that regulates sleep and wakefulness over a 24-hour period. Modern life, especially late-night screen time and irregular schedules, often disrupts this rhythm, causing insomnia or fatigue. Red light therapy might help reset or regulate your circadian rhythm by sending proper nighttime signals to your brain.

Using red light therapy in the evening replaces harmful blue light, preventing confusion in your internal clock. Over time, consistent red-light exposure can help your body recognize night and day clearly again.

Some research shows that controlled red light exposure, combined with regular light patterns, can directly support circadian rhythm alignment. Participants in one study felt more alert in the afternoon after regular red light use, suggesting a stabilized internal clock.

However, red light therapy alone isn’t typically strong enough to fully correct serious circadian rhythm disorders or extreme night-owl tendencies. Morning bright light therapy is usually more effective for major shifts. Still, red light therapy remains valuable as an evening routine to maintain or improve circadian health. Using red light regularly at night gradually trains your body to recognize bedtime naturally again.

How long before sleep should you use red light therapy?

Proper timing maximizes the sleep benefits of red light therapy. Generally, using red light therapy about 20 to 30 minutes before bedtime is most effective. A practical example is including a 10- to 20-minute red-light session as the final part of your evening routine, about half an hour before sleep.

For instance, if bedtime is 10 PM, begin your red-light session around 9:30 PM. During this time, keep other lights off or dim and avoid screens. After your session, transition calmly to bed in a dim or darkened room to maintain the benefits.

Why this timing? Twenty to thirty minutes gives your body enough exposure without becoming inconvenient. It mimics a natural sunset, signaling clearly to your brain that nighttime has begun. This approach aligns well with most research and user recommendations.

Always follow the instructions provided with your specific red-light device. Some products recommend shorter or longer sessions. If you’re new to red-light therapy, start with shorter durations of around 10 to 15 minutes and adjust as needed to find what feels best for your sleep.

Consistency matters most. Regular nightly use helps your body associate red-light exposure with bedtime, reinforcing your internal signals and supporting a healthier sleep schedule.
