How does light therapy work?

Light interfaces with chronic complaint biology via two main pathways:

• Mitochondrial & cellular modulation
  LEDs in the red to near-infrared range boost mitochondrial electron transport, increase ATP production, and reduce reactive oxygen species. In fibromyalgia patients, whole-body LED PBM (660/850 nm) improved pain scores, suggesting systemic mitochondrial support (Navarro-Ledesma et al., 2023). Navarro-Ledesma et al., 2023
• Inflammation & cytokine regulation
  LED PBM modulates inflammatory pathways including NF-κB, cytokine release (IL-6, TNF-α) and nitric oxide balance. In a study of LED treatment in osteoarthritic joints, 850/940 nm LEDs reduced IL-6 and cartilage degradation markers (Choi et al., 2023). Choi et al., 2023

In practice, this implies combining regular LED exposure to support systemic cellular resilience with localized sessions to ease persistent tissue stress—all within a wellness framework.

Applications for chronic complaints

• Fibromyalgia / widespread pain
  Whole-body LED PBM (660/850 nm) in a triple-blind RCT produced significant reductions in pain and fatigue over weeks. Navarro-Ledesma et al., 2023
• Osteoarthritis / joint degeneration
  LED (850/940 nm) treatment in joint models reduced inflammatory markers and preserved cartilage structure. Choi et al., 2023
• Chronic joint pain / swelling
  Clinical LED intervention showed improvement in symptom scores and joint comfort in hand OA patients over multiple weeks. Kim et al., 2023/2024

Key benefits at a glance

• Lower pain and improved daily function — Clinical LED in hand OA and fibromyalgia showed symptom reductions. Navarro-Ledesma et al., 2023 Park et al., 2023/2024
• Reduced inflammation markers — 850/940 nm LED reduced IL-6 and cartilage degradation metrics. Choi et al., 2023
• Enhanced cellular resilience — Systemic LED PBM improves mitochondrial capacity and fatigue tolerance. Navarro-Ledesma et al., 2023
• Safe & well tolerated — Studies report no adverse events with LED use in chronic settings. Navarro-Ledesma et al., 2023 Kim et al., 2023/2024

Who can benefit?

Individuals with persistent pain, low-grade inflammation, or slow tissue recovery—especially in joints or soft tissue—who seek a gentle, evidence-based adjunct to lifestyle, movement, and rest. This content is informational, not a medical prescription.

How to use it in practice

Local application:
10–20 minutes, 3–5 times per week, at a distance of 10–30 cm.

Target zones:
Joints, tissues with discomfort or stiffness, or regions with sluggish recovery.

Consistency over intensity — regular use over weeks supports cumulative effects on circulation, pain relief, and resilience.

Scientific context

Recent LED-based evidence supports use in chronic conditions:

• Whole-body 660/850 nm LED PBM improved symptoms in fibromyalgia (RCT). Navarro-Ledesma et al., 2023
• 850/940 nm LED reduced inflammation and preserved cartilage in OA models. Choi et al., 2023
• High-density LED in hand OA improved joint comfort over weeks. Kim et al., 2023/2024

These findings support LED PBM as a wellness-connected tool, not a substitute for medical or rehabilitative care.

Why redtreat

• Wavelengths aligned with LED clinical evidence (≈ 660/850 nm options)
• Designed for safe, repeatable delivery over soft tissues and joints
• Swiss-designed reliability and precision for home or clinical use
