2. Product Functions

When it comes to discovering the potential benefits of red light therapy, you can actually thank NASA. In 1995, the second U.S. Mir/Gravity Laboratory mission (STS-71 Columbia) first used red light sources for plant growth experiments in space. During this experiment, astronauts noticed that small scratches on their hands healed faster than expected. This phenomenon caught NASA's attention, leading to extensive research on the applications of red light in treatment. These studies found that exposing the skin to low levels of red or near-infrared light could provide therapeutic benefits. These wavelengths of light can penetrate the skin and be absorbed by cells, leading to:

• Increasing Cellular Energy: Red and near-infrared light stimulate the mitochondria within cells to produce more ATP (adenosine triphosphate), thereby raising the energy levels of the cells and making them more active.
• Improving Blood Circulation: Red light therapy can enhance local blood circulation and increase blood flow in the treated area. Enhanced blood circulation can deliver more oxygen and nutrients to tissues while accelerating the removal of metabolic waste, aiding in tissue repair and regeneration.
• Reducing Inflammation: Red and infrared light can reduce inflammatory responses through various mechanisms. It can lower the levels of pro-inflammatory cytokines and increase the production of anti-inflammatory cytokines, helping to alleviate inflammation and swelling. This is particularly beneficial for treating inflammatory conditions such as arthritis and muscle soreness.

Applicable symptoms include, but are not limited to:

• Pain Relief: Alleviating chronic pain, including arthritis, joint pain, and muscle soreness.
• Wound Healing: Accelerating the healing of wounds, cuts, and burns.

To achieve the best results, we recommend:

• Wearing Method: Wear the red light therapy pad on the area needing treatment, ensuring the light source is in direct contact with the skin. Note that wearing different clothes or different thicknesses may cause some light to be blocked, reducing the effect. Effectiveness: Minimal, no obstruction > thin, transparent clothes. Minimal skin thickness, transparent clothing of other colors.
• Usage Duration: Each session should last about 20 minutes. Adjust the settings according to personal needs and comfort. Beginners should start with the lowest setting and gradually increase.
• Frequency: Use on the same area 1-2 times a day. Continuous use over a period of time is required to achieve the best results. Avoid overuse.

The expected effects may vary with different durations of continuous use: Short-term effects: After the initial use, you may feel localized warmth and comfort, which is normal. Mid-term effects: After 1-2 weeks of continuous use, you may find that pain and discomfort have lessened, and muscle fatigue recovers more quickly. Long-term effects: After 4-6 weeks of continuous use, you may notice improved skin quality, faster wound healing, and significant relief from chronic pain.

8. Troubleshooting

Here are some common questions about this product and its solutions, if you can't find the solutions to your question here, please contact the after-sales service: service.help@comfytemp.com

1. After using for a period of time, the device shuts down.

Cause: This product has a default timer setting, in the absence of selecting a timer via the app, the product will shut down after 20 minutes.

Solution: You can restart the device for further use. However, we do not recommend using it multiple times on the same body part. According to scientific evidence, longer usage does not necessarily yield better results; scientific evidence indicates diminishing returns. It's sufficient to use it for 20-30 minutes. Prolonged use increases the likelihood of cellular dehydration.

2. When using the NIR mode, I found that the lights are not on.

Cause: In the NIR mode, the lights emit 850nm near-infrared light, which is invisible to the naked eye. Therefore, it's not that the lights are not on; it's just that our eyes cannot perceive this wavelength.

Solution: By checking the indicator light in the battery case, we can observe that it is still on, indicating that the device is still active. Additionally, after using this mode for a while, one can feel the heat generated by the device.

3. During the first use, apart from feeling warmth, there seems isn't any other feedback.

Cause: The red light therapy works in two ways, through photobiomodulation and thermal effects. Photobiomodulation mainly stimulates mitochondria within cells, accelerating cellular metabolism, promoting cellular activity, and stimulating the formation of collagen in the skin. This aspect takes some time before noticeable effects occur. On the other hand, the thermal effect is immediately perceptible. The generated heat is felt within the body, unlike heating pads, which primarily affect the skin surface.

Solution: Abundant scientific data indicates that using it for 20 minutes per day can yield noticeable results as early as three weeks.

9. Attention Points

Absolute Contraindications for Red Light Therapy

• Red light therapy should not be used on burns that occurred within the last 24-48 hours unless it has been cleared by the doctor providing treatment for the burn, as red light therapy may add heat to the overheated tissues, causing further thermal damage.
• Malignant Cancers, especially carcinomas. Theoretically, red light therapy can speed the growth or spread of cancerous cells by encouraging cell proliferation, it should not be used.
• Hyperthyroidism (Neck and Upper Chest Only). When red light therapy is used over the neck and upper chest, it is likely that light will reach the thyroid, increased stimulation of the thyroid may cause a worsening of symptoms caused by an already overactive thyroid. Those with hyperthyroidism should not use red light that may reach the thyroid without the permission of their endocrinologist.
• Epilepsy. People with epilepsy may be susceptible to flicker in red light panels and could experience a seizure if the flicker is severe or if they are particularly sensitive.
• Pregnancy (Abdomen Only). Development during pregnancy involves a delicate balance of many complex biological processes. Anything that could potentially affect this process should be approached with great care. For this reason, red light therapy during pregnancy should generally be avoided if it could reach the developing fetus.
• Eye Disease (Eye Only). While the effect of red light therapy on healthy eyes is still being debated, it should never be used on those who have an eye disease.

Relative Contraindications for Red Light Therapy

• Fever or infection. During fever and infection the body temperature is elevated. There is a risk that the increased heat created by red light therapy may contribute to temperature elevation throughout the body. While this risk is relatively benign, as it is unlikely that the heat created by red light therapy will significantly raise body temperature during a fever.
• Someone who has a severely elevated body temperature should discuss the risks and benefits of red light therapy before using it.
• Systemic Lupus Erythematosus (SLE). Systemic Lupus Erythematosus (SLE) is an autoimmune condition in which the body's immune system attacks connective tissue through the body. People with SLE may be more susceptible to damage from light, with a skin rash caused by sunlight being common with this condition.
• Severe Bleeding or Blood Loss. Red light therapy should not be used when serious bleeding is occurring unless it has been cleared by a doctor.

Additional Considerations for Red Light Therapy

• Tattoos - Tattoos, especially ones that use red ink, may be prone to fading when exposed to intense red light. The tattoo ink may also cause uneven absorption of red light, causing therapy to be less uniform.
• Dark skin pigmentation - The effect of skin pigmentation on red light therapy is still being studied. Those with darker skin tones may find that their skin absorbs more light, making it warmer than those with lighter skin tones would experience. A smaller amount of red light may actually reach deeper tissues, however, its effect is not likely to be large.
• Dark hair - Darker colors of hair may absorb more light, causing increased warmth and decreased penetration of red light. This effect is not likely to be large.
• Melasma / Hyperpigmentation - Our own product study showed improvement from red and NIR light on hyperpigmentation, particularly when paired with a high antioxidant serum. However, in rare instances users can experience the opposite effect. We suggest starting slowly and using red light only if this is a concern.
