Understanding Near Infrared Light
Near infrared light is a type of electromagnetic radiation that is invisible to the human eye. The wavelengths of near infrared light range from about 750 nanometers to 2500 nanometers, sitting just outside the visible red end of the light spectrum. Although we cannot see near infrared light, it offers many potential therapeutic benefits.
How Near Infrared Light Works
When near infrared light is absorbed by human cells, it stimulates cellular processes and boosts ATP (adenosine triphosphate) production. ATP is the key source of energy that powers many important biological processes in the body. By increasing ATP levels, near infrared light can improve cell health, vitality and function.
Scientists believe that near infrared light may also stimulate the mitochondria. The mitochondria are the powerhouses within our cells that take nutrients and turn them into cellular energy. By activating the mitochondria, near infrared light promotes improved overall cell functioning.
Benefits of Near Infrared Light
Although research is still emerging in this exciting field, studies suggest many purported benefits of near infrared light therapy:
- Reduced inflammation and chronic joint pain
- Faster wound, bone, muscle and nerve healing
- Enhanced skin health and appearance
- Increased circulation and tissue oxygenation
- Elevated mood and improved sleep quality
- Protection against oxidative stress and damage
Let's explore some of the current evidence surrounding these potential therapeutic uses of near infrared light.
Near Infrared Light for Inflammation and Pain
Chronic low grade inflammation is believed to underlie many modern health conditions. As an anti-inflammatory agent, near infrared light may help mediate inflammatory pathways that contribute to chronic joint pain or disorders like arthritis, fibromyalgia and back pain.
In one double blind trial on people with rheumatoid arthritis, near infrared light therapy significantly reduced pain and morning stiffness compared to placebo treatment after only four weeks. Studies have also shown decreased inflammation and pain levels in patients with dysphonia and oral mucositis after near infrared light therapy.
Wound and Injury Healing
By increasing circulation and oxygenation while stimulating ATP production, near infrared light can accelerate healing for many types of injuries and wounds such as burns, ulcers, bone fractures and nerve damage. Human and animal studies demonstrate faster wound closure times, enhanced skin graft survival and improved nerve regeneration and functionality when treated with near infrared wavelengths.
Anti-Aging Effects on Skin
Near infrared light is believed to stimulate collagen production while reducing inflammation and redness in skin cells. This results in an anti-aging effect, with improvements seen in skin complexion, smoothness, fine lines/wrinkles and hyperpigmentation disorders such as melasma. Regular application may also enhance skin moisture and elasticity for an overall more youthful appearance.
Is Near Infrared Light Safe?
Near infrared light therapy is considered very safe as long as appropriate parameters and dosages are utilized. There are generally no adverse side effects. However, its recommended to consult your doctor or healthcare professional before beginning treatment if you have any specific health conditions or concerns.
At-Home Near Infrared Light Devices
There are many at-home near infrared light therapy devices available to provide convenient, non-invasive treatment. These typically use LEDs (light emitting diodes) to deliver therapeutic wavelengths that can penetrate skin and tissue.
Some popular types of in-home near infrared devices include:
- Near infrared heating pads
- Near infrared lamps or light panels
- Portable near infrared wands or sticks
- Near infrared intranasal devices
When shopping for at-home near infrared light products, always look for reputable brands that disclose wavelength, power density and dose settings. Follow manufacturer instructions carefully.
The Future of Near Infrared Light
Human clinical studies continue to elucidate the promising health and anti-aging effects of near infrared light therapy. However, specific treatment parameters for medical conditions still need optimization.
Moving forward, near infrared light is poised to become an innovative, non-invasive and drug-free therapy option for improving wound healing, reducing pain and inflammation, reversing skin aging and more as the supporting evidence continues to build.
FAQs
What are the main benefits of near infrared light therapy?
Research indicates near infrared light therapy may help reduce inflammation and chronic joint pain, accelerate healing of wounds and injuries, enhance skin health and appearance, increase circulation and tissue oxygenation, elevate mood and improve sleep quality.
Is near infrared light treatment safe?
Yes, near infrared light therapy is considered very safe as long as appropriate parameters and dosages are used. There are typically no adverse side effects, but you should consult your doctor before beginning treatment if you have any specific medical conditions.
How often should I use my near infrared light device?
Most manufacturers recommend using near infrared devices about 3-5 times per week for best results. Daily use is fine as well for shorter sessions. It's important not to exceed dosage recommendations.
How soon will I notice benefits from near infrared therapy?
Some users report an immediate temporary reduction in joint or muscle pain after near infrared light treatment. However, more lasting anti-inflammatory, wound healing and anti-aging benefits emerge after several weeks to months of consistent sessions 2-3 times per week.
