Here's why.
1. Regulating circadian rhythm
Red-light wavelengths (around 630–700 nm) have minimal impact on melanopsin, the light-sensitive protein in the eyes that responds strongly to blue light.
- Blue light suppresses melatonin production (the sleep hormone), but red light does not.
- Evening exposure to red light can actually help signal to the brain that it’s time to wind down, supporting a healthy circadian rhythm.
2. Boosting melatonin production
Some studies show red and near-infrared light can increase natural melatonin levels:
- By reducing oxidative stress in the pineal gland (which produces melatonin)
- By promoting nitric oxide release and better blood flow, supporting hormonal balance
3. Enhancing relaxation via mitochondrial support
Red-light therapy boosts ATP production in brain and muscle cells, improving cellular efficiency.
- This may reduce nighttime muscle discomfort, headaches, or stress that can interfere with falling asleep.
4. Research evidence
- Zhao et al., 2012 (Journal of Athletic Training) – Female athletes exposed to red-light therapy before bed for 14 days had improved sleep quality and increased melatonin levels.
- Figueiro & Rea, 2010 – Found that exposure to low-level red light before bedtime did not suppress melatonin, unlike blue or white light, and supported better circadian alignment.
- Huang et al., 2019 – Demonstrated that photobiomodulation reduced oxidative stress and improved hormonal regulation, potentially enhancing sleep quality.
✅ In short: Red-Light Therapy may improve sleep by supporting circadian rhythm, boosting natural melatonin production, reducing nighttime discomfort, and promoting overall relaxation—helping the body and mind wind down for restful sleep.
