Product description

670nm Red Light Sleep Aid Lamp

The top center circle area is the touch area, which can be lightly touched to change the light mode, and long pressed to adjust the brightness.

Potential benefits of 670m red light for sleep

Promote melatonin secretionReduce sleep disturbancesAssist in regulating biological rhythms

1. Promote melatonin secretion

The inhibitory effect of red light (wavelength 600-700m) on melatonin is significantly lower than that of blue light. Some studies have shown that exposure to red light before bedtime may slightly increase melatonin levels, such as:

Experiments on female basketball players found that exposure to 670mm red light for 30 minutes every night for 14 days resulted in higher levels of melatonin in the experimental group compared to the control group;Animal experiments have also shown that red light may indirectly affect melatonin secretion by regulating the suprachiasmatic nucleus (biological clock center).

2. Reduce sleep disturbances

Replacing blue light: Blue light (400-480m) from electronic devices strongly inhibits melatonin, while red light has almost no such effect and is more suitable for nighttime use,Reduce neural excitability: Red light can slow down brainwave activity, induce the brain to enter a relaxed state, and shorten sleep time.

3. Assist in regulating biological rhythms

Regular exposure to red light may help synchronize circadian rhythms, especially for insomnia caused by light disturbances (such as shift workers).

Analysis of the mechanism of 670nm red light sleep aid

Retinal signal transductionActivation of mitochondrial energy metabolismNeuroendocrine regulationPsychological and behavioral effects

670nm red light mainly affects sleep through the following biological pathways

1. Retinal signal transduction: The intrinsic photosensitive retinal ganglion cells (ipRGCs) in the retina are sensitive to blue light, while red light, due to its longer wavelength, has weaker activation and therefore transmits fewer “wakefulness signals” to the brain, reducing interference with sleep.

2. Activation of mitochondrial energy metabolism: Red light can penetrate tissues, be absorbed by cellular mitochondria, promote adenosine triphosphate (ATP) synthesis, and enhance cellular activity:

In the fundus, improve retinal metabolism, alleviate visual fatigue (indirectly promote relaxation);Whole body irradiation may regulate energy metabolism pathways related to sleep.

3. Neuroendocrine regulation

Melatonin pathway: Red light may inhibit the interference of blue light on the pineal gland or directly stimulate the synthesis of melatonin precursors;Cortisol control: Some studies suggest that red light may lower nighttime cortisol (stress hormone) levels.

4. Psychological and behavioral effects: Warm toned red light creates a soothing environment, reduces anxiety, and creates a “sleep ritual” that promotes sleep from a psychological perspective.

Attention：No built-in battery，Timer available only if light is on

670nm red light may assist sleep through a dual pathway of reducing melatonin inhibition and promoting physiological relaxation, but it is not a universal solution.

The effectiveness depends on individual differences and usage methods. It is recommended to use low-intensity devices with precise spectra as part of comprehensive sleep management.

Red Light Therapy for Sleep: 670nm wavelength red light simulates the warm red light at sunset, mainly by promoting melatonin secretion, blocking blue light, reducing nerve excitement, lowering cortisol (stress hormone) levels, relieving visual fatigue, creating a soothing environment, and reducing anxiety to improve sleep.
Natural Sleep Aid Lamp: This red light sleep aid device uses clinical grade LED beads to ensure pure red light with a wavelength of 670nm. The light intensity ≤ 40 lux at 4 feet, making it suitable for bedroom who are sensitive to light and have irregular sleep patterns to improve their sleep. Create a relaxing atmosphere before bedtime, during meditation, and yoga.
4 Modes Red Nightlight: The top circular area is the touch effective area, Single tap touch on the effective area can switch between 4 lighting modes: 670nm red light, 2700K warm white light, 4000K natural white light, and 6000K cool white light. This product has no built-in battery and does not provide a power adapter. We provide a Type C Power cord and have a built-in USB port for charging the phone.
Dimmable, Timeable: The top circular area is the touch effective area, long press the top effective area to achieve stepless brightness adjustment between 10% and 100%. Timer available only if light is on, it can be timed for 0.5 hours, 1 hour, 2 hours, and set the time to promote your sleep and relaxation according to your sensitivity to light.
Healthy Gift: The exquisite packaging box contains a red night light, Type C Power cord(59inches, 1.5m, No built-in battery for better sleep aid effect ), instruction manual. It is a healthy gift for yourself, family, and friends to improve sleep, and to create a relaxed and pleasant atmosphere for bedtime, meditation, yoga, relaxation, reading, and other activities.
