Red Light Therapy: A Solution to Help Alleviate Pain and Inflammation

Red Light Therapy: A Solution to Help Alleviate Pain and Inflammation

Red Light Therapy (RLT), also known as photobiomodulation, low-level light therapy (LLLT), and cold laser therapy, has emerged as a promising solution for pain management and inflammation control [1]. This therapeutic technique harnesses low-level wavelengths of red light, a practice rooted in a serendipitous discovery made by Endre Mester in 1967, which found that certain light could promote healing and hair growth in rats [1].

Considering the effectiveness of RLT in promoting wound healing, enhancing blood circulation, and facilitating tissue repair, its applications extend to addressing conditions such as osteoarthritic pain and tendinitis, improving muscle tissue health [1]. Scientific research continues to reveal the benefits of red light therapy and its potential as a non-invasive treatment option for various health issues[1].

Understanding Red Light Therapy

Red Light Therapy (RLT) is a modern treatment approach that utilises low wavelength red light to not only enhance skin appearance but also to address a variety of medical conditions [2].

The core mechanism behind RLT involves the absorption of light by cells, particularly the mitochondria, which are known as the powerhouse of the cell. This absorption stimulates the mitochondria to produce more adenosine triphosphate (ATP), which is the energy currency of the cell, thereby promoting cell repair and healing [4]. The process includes:

  • Exposure: The skin is exposed to low levels of red and near-infrared light, typically penetrating the skin sufficient to reach targeted cells and tissue structures[1].
  • Mitochondrial Activation: The primary aim is to boost the mitochondria within the cells, potentially increasing the efficiency, rejuvenation, and repair of cells [1].
  • LED Technology: Light Emitting Diodes (LEDs) are preferred for this therapy due to their nonablative and nonthermal properties, which can potentially increase blood flow, reduce inflammation, and enhance collagen production [1].

    RLT is unique in its approach as it does not rely on heat, nor does it expose the skin to harmful UV rays, positioning it as a safe treatment option for people [4]. The therapy is known to stimulate fibroblasts in the skin, improving cellular function and boosting collagen production, which is vital for skin and muscle tissue repair [6]. Both red and infrared light wavelengths are employed in RLT, each offering distinct benefits for skin and tissue repair [6].

    While RLT is generally considered safe for short-term use when applied as directed, and there are no known side effects [5].

 

Benefits of Red Light Therapy for Pain and Inflammation

Red Light Therapy (RLT) has been recognised for its ability to alleviate pain and inflammation, offering hope for those suffering from chronic conditions. Here are some of the ways RLT can be beneficial:

  1. Muscle Healing and Joint Mobility:
    • RLT promotes muscle healing, which can be particularly beneficial after intense physical activity or muscle strain [7].
    • In cases of osteoarthritis, RLT has been successful in reducing pain by over 50%, significantly improving the quality of life for patients [7].
    • Joint mobility improvements have been noted, allowing for greater comfort and range of motion [7].
  2. Collagen Production and Tissue Repair:
    • By stimulating collagen production, RLT helps maintain healthy cartilage and joint tissue, which are essential for pain-free movement [7].
    • The therapy's ability to stimulate cellular activity leads to anti-inflammatory responses, aiding in the recovery process of various tissues [8].
    • RLT has shown promise in reducing inflammation across numerous animal disease models, suggesting its broad applicability in human health [8].
  3. Energy Production and Tissue Health:
    • An increase in ATP production means that the body has more energy to facilitate tissue repair, contributing to pain and inflammation relief [2].
    • RLT's role in combating oxidative stress and aiding in the treatment of periodontitis highlights its versatility in addressing different inflammatory conditions [2].
    • Chronic wound healing is another area where RLT has shown potential, encouraging new skin growth and the formation of blood vessel networks [2].

      Additional benefits of RLT include improved skin elasticity due to increased collagen production, aiding in tissue repair through fibroblast production, and enhancing circulation between blood and tissue cells [9]. These effects not only contribute to pain management but also offer aesthetic advantages, such as improved facial texture and reduced wrinkle severity [9]. While RLT is being explored for a variety of medical uses, from reducing chemotherapy side effects to preventing cold sores, it is important to remember that ongoing research is crucial to fully understand its capabilities and limitations [9][3].

 

How to Use Red Light Therapy for Best Results

To harness the full potential of Red Light Therapy (RLT) for pain relief and inflammation reduction, it's essential to follow a few key guidelines:

  • Dosage Matters:
    • For skin-related treatments, an optimal dose of 4-6 Joules/cm2 is recommended, while deeper tissue issues may require a more robust dose ranging from 50-100 Joules/cm2 [11].
    • To achieve maximum benefits, ensure the use of LED lights that provide clinically proven red-light wavelengths between 630-680nm and near-infrared light waves between 800-880nm. Devices with a low EMF output are also preferable [11].
  • Consultation and Usage:
    • Always consult with a healthcare provider before starting RLT to ensure it's appropriate for your specific health needs [1].
    • For effective results, use an RLT device 2-3 times a week for 15-25 minute sessions. However, depending on your specific needs and desires from therapy, clinics offering RLT may use panels that have much higher energy output than home use ones therefore treatment will need to be tailored to the individual [6].
    • Consistency is crucial; maintain regular sessions to start seeing the desired outcomes [6].

Remember, while RLT is generally safe with no significant side effects when used as directed, it's not an instant solution. Patience and dedication are required as it takes time to build collagen, heal tissues, and stimulate cell regeneration [13]. Following these guidelines can help you maximise the therapeutic benefits of Red Light Therapy in your wellness routine.

Possible Risks and Considerations

While Red Light Therapy (RLT) is recognized for its therapeutic benefits, it's essential to be aware of the possible risks and considerations before undergoing treatment:

  • Improper Use and Overexposure Risks:
    • Tissue and cell damage can occur if RLT is used improperly or if there's overexposure to the light [4].
    • Damage to unprotected eyes are potential risks, highlighting the importance of following usage guidelines and wearing eye protection [4] [1].
  • Cost and Accessibility:
    • Treatments can vary significantly in price, ranging from ￡30 to over ￡80 per session, with at-home devices costing from ￡120 to several hundred pounds [2].
  • Safety and Effectiveness:
    • The scientific community has not reached a consensus on RLT's effectiveness and safety, particularly in relation to cancer treatment [1].
    • People with cancer or a history of cancer, as well as those with sensitive skin, diabetes, or who are pregnant, are advised to consult with their healthcare provider before using RLT [1] [2].

      It is crucial to consult a healthcare professional before beginning any new treatment and to utilise RLT devices.
