Redlight and Near-Infrared Light Therapy: Rejuvenate Your Wellness
Red light therapy (RLT) and near-infrared light therapy (NIR) are forms of low-level light therapy (LLLT) that use specific wavelengths of light to stimulate various biological processes in the body. They are often used for therapeutic and cosmetic purposes due to their ability to penetrate the skin and affect cells and tissues.
Red Light Therapy (RLT):
Wavelengths: Typically uses light in the range of 620–750 nanometers (nm).
Penetration: Red light can penetrate the skin at shallow depths, typically around 2-5 mm.
Uses:
- Stimulates collagen production (which can improve skin elasticity and reduce wrinkles).
- Improves circulation and wound healing.
- Reduces inflammation and pain.
- Treats conditions such as acne, eczema, psoriasis, and rosacea.
- Used in muscle recovery, joint pain, and overall skin health.
Benefits:
- Anti-aging: Helps reduce wrinkles, fine lines, and sagging skin.
- Wound healing: Speeds up the repair of skin and soft tissue injuries.
- Pain relief: Reduces muscle and joint pain.
- Reduced inflammation: Both therapies can significantly reduce inflammation.
- For high-performance athletes (and those who train like them) LED light therapy can help accelerate muscle repair following fatigue and injury. Mitochondria within cells are particularly responsive to LED light therapy, and muscle cells are exceptionally rich in mitochondria. LED light therapy may also stimulate stem cells, further assisting in muscle recovery.
Near-Infrared Light Therapy (NIR):
Wavelengths: Usually operates in the 700–1200 nm range.
Penetration: Near-infrared light can penetrate deeper into the body, up to 5 cm or more, reaching muscles, joints, and even bones.
Uses:
- Increases cellular energy (ATP production) by stimulating the mitochondria.
- Promotes tissue repair and regeneration.
- Reduces inflammation in deeper tissues, muscles, and joints.
- Assists in recovery from injuries or surgeries.
- Improves circulation and helps with muscle recovery and pain management.
How It Works:
Both red and near-infrared light therapies work by promoting the production of adenosine triphosphate (ATP) in the mitochondria of cells. This increased energy allows cells to repair and regenerate more efficiently, which aids in healing and reduces inflammation. These therapies also increase blood flow, which further supports tissue repair and reduces pain.
Safety and Side Effects:
These therapies are generally considered safe, non-invasive, and free of significant side effects when used appropriately. Overexposure or improper use of devices, however, may lead to temporary skin irritation or discomfort.
Near-Infrared (NIR) Light Benefits
Near-infrared (NIR) light reduces overall inflammation in the body by decreasing the presence of inflammatory markers. This reduction can help ease the symptoms associated with joint pain, sore muscles, autoimmune diseases, arthritis, traumatic brain injuries, and spinal cord injuries.
