Why does the LZR Ultrabright combine red light with infrared (IR) light therapy?

Infrared light therapy, often used alongside or in conjunction with red light therapy, offers a range of additional benefits due to its ability to penetrate deeper into the body’s tissues. The 810nm wavelength is considered the sweet spot for combining maximum depth of penetration with a positive photo-chemical reaction. For optimal photobiomodulation (PBM), 810nm is the primary and most desired wavelength according to top laser research doctors and scientists. European laser specialists such as Dr. Weber and Dr Hamblin promote 810nm as the optimum wavelength because it is said to produce the maximum interaction with the mitochondria, which is the powerhouse of the cell and responsible for converting the photonic energy from the light into ATP. Due to the deep penetration of 810nm combined with beneficial effects throughout the entire musculoskeletal system, joints, spine and all soft and hard tissues, patients tend to experience long term healing with a treatment regimen of 6-12 treatments.

Here are some of the additional benefits of infrared light therapy:

  1. Improved Circulation: Infrared light therapy enhances blood flow and vasodilation, leading to improved circulation. This can help with the delivery of oxygen and nutrients to cells and promote overall cardiovascular health.
  2. Pain Relief: Infrared light therapy is effective in reducing pain and discomfort associated with various conditions, such as muscle aches, joint pain, and chronic pain syndromes. It works by increasing blood flow, relaxing muscles, and reducing inflammation.
  3. Muscle Recovery: Athletes and fitness enthusiasts often use infrared therapy to accelerate muscle recovery after intense workouts. It helps reduce muscle soreness, stiffness, and the risk of injury.
  4. Detoxification: Infrared therapy can aid in the detoxification process by eliminating toxins and heavy metals from the body through the skin.
  5. Wound Healing: Infrared light therapy can enhance wound healing by stimulating tissue regeneration and collagen production, making it beneficial for both acute and chronic wounds.
  6. Relaxation and Stress Reduction: Infrared light therapy sessions are often calming and soothing. They can help reduce stress, improve sleep quality, and promote relaxation.
  7. Immune System Support: Some research suggests that infrared therapy may have immune-boosting effects, potentially enhancing the body’s defense mechanisms against infections.
  8. Skin Health: Infrared light can improve skin elasticity and reduce the appearance of scars and stretch marks. It may also help with conditions like cellulite.
  9. Arthritis and Joint Health: Individuals with arthritis often find relief from pain and increased joint mobility through infrared therapy and the corresponding reduction of inflammation that it is known to help with.
  10. Metabolism and Weight Management: While not a replacement for diet and exercise, infrared therapy can support weight management by increasing metabolism and promoting the breakdown of fat cells.
  11. Neurological Health: Emerging research suggests that infrared therapy may have neuroprotective effects and could be beneficial for conditions like Alzheimer’s disease and traumatic brain injury. However, more research is needed in this area.
  12. Cognitive Function: Some studies have explored the potential cognitive benefits of infrared light therapy, including improved memory and cognitive function. Again, more research is needed to establish these effects conclusively.

It’s important to note that the specific benefits of infrared light therapy can vary depending on the wavelength used and the target area. The therapy should be used under the guidance of a healthcare professional or in accordance with the manufacturer’s recommendations to ensure safe and effective treatment.
