Science behind Red light and Infra light therapy
Carpal Tunnel Syndrome occurs when the median nerve—which runs through a narrow passageway called the carpal tunnel in the wrist—becomes compressed or irritated. This nerve controls sensation and movement in the thumb, index, middle finger, and part of the ring finger.
Because the carpal tunnel is a confined space, even small changes such as inflammation, swelling, fluid retention, or thickened tendons can increase pressure on the median nerve.
What Causes This Nerve Compression?
- Repetitive hand and wrist movements (typing, cooking, care giving, doing dishes)
- Inflammation of surrounding tendons (tenosynovitis)
- Poor wrist posture or prolonged flexion/extension
- Fluid retention (often influenced by hormones)
- Tissue irritation from overuse or micro-injuries
As pressure builds, the nerve begins to conduct signals less efficiently, leading to:
- Tingling or numbness in the fingers
- Wrist or forearm discomfort
- Weak grip strength
- “Electric shock” sensations
- Night-time symptoms due to wrist position
CTS often progresses gradually, and early care can help reduce strain on the nerve and improve wrist function.
How Infrawrap Helps: Red & Infrared Light (650 nm + 850 nm)
Infrawrap combines 650 nm red light with 850 nm near-infrared (NIR) light, two wavelengths widely studied for their supportive effects on tissue health, circulation, and inflammation.
Both wavelengths penetrate the skin at different depths, making them complementary for wrist and nerve-related discomfort.
650 nm Red Light (Surface–Level Benefits)
Red light at 650 nm primarily targets skin-level and superficial soft tissues:
✔ Supports micro-circulation
Improved blood flow helps deliver oxygen and nutrients to strained tendons and ligaments in the wrist.
✔ Aids recovery of irritated soft tissues
This wavelength supports the mitochondria in cells—helping them produce energy more efficiently, which can assist the natural healing processes in overused tendons or connective tissues.
✔ Reduces surface-level stiffness
Many users experience “warming relief,” which helps loosen tight wrist structures that may contribute to median nerve pressure.
850 nm Near-Infrared Light (Deeper Penetration)
Near-infrared light penetrates much deeper—reaching the tissues inside the carpal tunnel area.
✔ Helps decrease deep-tissue inflammation
850 nm NIR is associated with helping calm inflammation around the flexor tendons, which is a major contributor to median nerve compression.
✔ Supports nerve comfort
Some studies suggest that NIR light may help improve nerve cell metabolism and conductivity, supporting the median nerve’s ability to function smoothly.
✔ Promotes deeper circulation
This helps reduce stagnant swelling and encourages fluid movement, which can help reduce pressure in tight spaces like the carpal tunnel.
Why Infrawrap Is Helpful for Carpal Tunnel Syndrome
Infrawrap delivers light exactly over the carpal tunnel region, where tight tissues, swollen tendons, and nerve compression occur.
How It Supports Wrist Comfort:
- Encourages better blood flow to irritated tendons
- Supports natural anti-inflammatory processes
- Helps relax tight or overworked wrist structures
- Supports the median nerve by reducing surrounding pressure
- Provides soothing warmth that can ease stiffness and tension
While Infrawrap is not a medical treatment for CTS, it can be a helpful, non-invasive wellness tool for busy mums experiencing wrist discomfort from overuse, inflammation, or repetitive strain.
