Quality sleep is one of the most important foundations of good health, yet it’s also one of the most overlooked. Busy schedules, screens, stress, and disrupted routines can make it harder for your body and mind to wind down at night.
If you're getting 7-8 hours but still waking up tired, or if falling asleep feels like a nightly struggle, the issue might not be how long you're sleeping, it's how well your body is preparing for rest.
That’s why more people are turning to red light therapy as a gentle, natural way to support deeper, more restorative sleep. Unlike blue light, which overstimulates the brain and suppresses melatonin, red and near-infrared wavelengths help calm the nervous system, balance circadian rhythms, and prepare your body for rest.
And with powerful at-home devices like the JNH Lifestyles LT-100 and LT-300, creating a nightly sleep-supporting routine has never been easier.
The Science: How Red Light Therapy Supports Better Sleep
1. Supports Natural Melatonin Production
Your circadian rhythm - your internal body clock - is highly sensitive to light. Blue light (from phones, TVs, and LEDs) signals your brain to stay alert and suppresses melatonin production. Red light does the opposite.
Wavelengths in the 630–850nm range don't disrupt melatonin like other light sources do. Research shows that red light exposure in the evening can support healthy melatonin levels, helping your body recognize it's time to wind down.*
- Lowers Cortisol and Calms the Nervous System
Chronic stress keeps cortisol elevated, making it difficult to relax at night. Studies have shown that red and near-infrared light therapy can help:
- Reduced cortisol levels
- Lower heart rate variability associated with stress
- Activate the parasympathetic nervous system (your "rest and digest" mode)*
This creates the physiological conditions your body needs to transition into deep, restorative sleep.
3. Enhances Cellular Repair During Sleep
Sleep is when your body does its most important work:
- Repairing tissue
- Regenerating cells
- Clearing metabolic waste
- Rebalances hormones
Red light therapy boosts ATP (cellular energy) production, which means your body has more resources to recover efficiently through the night. Better cellular function during sleep translates to waking up feeling more restored.*
How to Use Red Light Therapy for Better Sleep
For the best results:
- Use 10 - 20 minutes before bed (ideally 30 - 60 minutes before sleep)
- Position yourself 6 - 12 inches from the panel
- Dim or turn off surrounding lights
- Keep devices and screens away during your session
- Breathe deeply and allow your body to settle
Important timing note: Red light won't keep you awake like blue light does. The wavelengths used in therapy (630–850nm) are specifically chosen because they support relaxation rather than alertness. Many users find the session itself becomes a calming pre-sleep ritual.
JNH Red Light Panels for Better Sleep
LT-100: Compact Nighttime Therapy
Wavelengths:
- 660nm (Red)
- 850nm (Near-Infrared)
Why it works for sleep:
- Compact enough for a nightstand or bedroom setup
- Targeted coverage perfect for a focused evening routine
- Delivers therapeutic wavelengths without overwhelming brightness
- Easy to incorporate into a 10-minute wind-down ritual
Ideal for: Individuals wanting a simple, effective nighttime routine or those with limited space.
LT-300: Full-Body Evening Relaxation
8 therapeutic wavelengths: 610nm, 630nm, 660nm, 810nm, 830nm, 850nm, 940nm, 1060nm
Why it improves sleep:
- Full-body coverage for comprehensive nervous system support
- Deeper wavelength penetration helps release physical tension
- More powerful calming effect for those with high stress or demanding schedules
- Supports whole-body recovery while you sleep
Ideal for: Those seeking maximum sleep support, athletes needing recovery, or anyone dealing with chronic stress or tension.
Both panels deliver the key wavelengths shown to support melatonin production and nervous system balance, with the LT-300 offering expanded coverage and deeper therapeutic benefits.
Why Red Light Therapy Works Better Than Other Sleep Solutions
Unlike pills, supplements, or sleep aids, red light therapy works with your body’s natural rhythms, not against it.
No drowsiness or grogginess: You're supporting natural sleep cycles, not forcing them
No dependency: Your body learns to regulate itself more effectively over time
No side effects: Just gentle wavelengths that support your biology
Long-term improvements: Consistent use helps restore healthy sleep patterns naturally
Addresses root causes: Rather than masking symptoms, red light helps regulate the systems that control sleep quality
Create Your Nighttime Ritual
Support deep sleep, balanced mood, and next-day energy by creating a soothing evening routine with red light therapy. Consistent use over 2–4 weeks typically yields the most noticeable improvements in sleep quality and morning energy.
