The Science Inside KYMIRA Infrared

What it is
KYMIRA’s patented KYnergy® infrared textile embeds a matrix of bioceramic minerals into each fibre. These minerals capture body heat and convert it into far infrared (FIR) light in the 6–14 µm range, a wavelength shown in clinical literature to penetrate tissue and stimulate beneficial biological responses that support circulation, oxygenation, energy production, and recovery.

How it works (step by step the headlines)

1. Energy conversion: Body heat → absorbed by mineral matrix → re emitted as FIR (6–14 µm).
2. Nitric Oxide Activation → Vasodilation
FIR exposure is linked to increased nitric oxide availability, promoting local vasodilation and improved micro circulation.
3. Enhanced Oxygen Delivery (tcPO₂)
Independent tcPO₂ studies show that FIR garments raise tissue oxygenation, supporting aerobic energy pathways at a lower physiological cost.
4. Mitochondrial efficiency: FIR accelerates cellular energy (ATP) production, aiding sustained output and reduced fatigue.
5. Improved Biological Signalling (Adaptation Support): Exercise studies show FIR garments activate signalling pathways related to mitochondrial biogenesis and angiogenesis
6. Thermal Comfort & Temperature Balance
FIR helps stabilise micro temperature during and after exercise, while the textile maintains breathability and moisture management.

Why it matters for performance

- Increased Power, Strength & Endurance Capacity
Improved oxygen delivery, faster aerobic system activation, and more efficient ATP energy production, combined with reduced oxygen consumption requirements, support higher sustained intensities and greater total work output, increased average power, stronger muscles, better neuromuscular efficiency, increased explosive power, coordination. In clinical trials by the University of Loughborough, wearing KYMIRA Infrared has been shown to improve athletic performance by up to 8.7% from first wear.

- Better Movement Quality & Soft Tissue Readiness
Enhanced local circulation and oxygenation help prime muscles to be stronger and more flexible, improving mobility, reducing stiffness, and supporting more consistent movement patterns during sessions. Clinical trials show users have better control and stability during high-speed movements, alongside increased jump height and grip strength.
Greater acute skeletal muscle adaptive responses during exercise, with increased mitochondrial and angiogenic signalling. Leading to quicker training adaptions biologically.

- Rapid in-session recovery: The same mechanisms support repair — removing waste products like lactic acid quicker, reducing muscle micro-tears that create DOMS, reducing in-session fatiguing and inflammation marker metabolites, and activating the pain and inflammation modulating pathways, reducing feelings of soreness.

Why KYMIRA Supports Injury Prevention
Enhanced local circulation and oxygenation help prime muscles to be stronger and more flexible, improving mobility, reducing stiffness, and supporting more consistent movement patterns during sessions. Clinical trials show users have better control and stability during high-speed movements. This prevents the creation of micro muscle tears that contribute to DOMS, and to larger soft-tissue injuries.

- Improved oxygenation supports efficient muscular contraction and reduces fatigue related injury risk.

- Cellular energy support (enhanced energy ATP production), reduced aerobic pathway and oxygen use, greater endurance and reductions in fatiguing metabolites in session, supports stable movement patterns and reduces compensatory mechanics from tiredness.

- Temperature regulation helps prevent cold related tightness and maintains muscle compliance.

- Accelerated recovery mechanisms, reductions in fatiguing metabolites, and reductions in inflammatory markers during and between sessions, reduce cumulative tissue stress experienced in session.

Increased angiogenic signalling and mitochondrial angiogenesis support quicker training adaptions for safer movements.


Why it matters for recovery

- Faster post exertion neuromuscular restoration & readiness
Peer reviewed athlete research shows that recovering in KYMIRA FIR garments can deliver highly significant neuromuscular recovery improvements at 24–48 h, compared to placebo. Objective markers of readiness to perform again after the prior session, show next athletic performance is significantly better following recovery in KYMIRA Infrared. Wearers are in a better biological state and have reduced physiological stress in objective measures.

- Reduced feelings of DOMS, soreness and inflammation.
Peer-reviewed research shows using KYMIRA Infrared significantly reduces athletes experiences of DOMS, and modulates pain relief and anti-inflammatory pathways, actively reducing both, with natural effects.
Passive, non powered recovery you can wear immediately after training, during travel, and overnight—no settings, no sessions to book—drives consistent use and better outcomes.

- Increased Circulation, Oxygenation & Quicker soft-tissue Repair
The observed tcPO₂ rise within 30–90 min aligns with the post session window when tissues need oxygen for remodelling and waste clearance, supporting reduced next day heaviness and smoother movement quality. This acceleration of recovery processes, continues as long sa your wear KYMIRA.

- Acute Skeletal Muscle Adaptive Responses During Recovery
Clinical studies show significantly increased mitochondrial and angiogenic signalling showing increased angiogenesis, neuromuscular training adaption results.
