The Science Inside KYMIRA® Recovery Baselayer

What it is
KYMIRA’s patented KYnergy® infrared textile embeds a matrix of bioceramic minerals into every fibre. These minerals capture body heat and convert it into far‑infrared (FIR) light in the ~6–14 µm band—wavelengths reported in peer‑reviewed research to penetrate tissue and stimulate beneficial biological responses that support circulation, tissue oxygenation, cellular energy (ATP) production, and recovery.

How it works — step by step

1. Energy conversion
Body heat → absorbed by the bioceramic matrix → re‑emitted as FIR (6–14 µm) to the skin and underlying tissue.
2. Nitric oxide (NO) availability → vasodilation
FIR exposure is associated with increased NO signalling, promoting local vasodilation and improved micro‑circulation, an important precursor for recovery.
3. Enhanced oxygen delivery (tcPO₂)
Independent, placebo‑controlled human trials show FIR garments increase transcutaneous oxygen (tcPO₂) by ~5–8% within 30–90 minutes versus control, supporting oxygen‑dependent repair processes.
4. Mitochondrial & angiogenic signalling (ATP support)
Exercise and recovery studies report up‑regulation of mitochondrial and angiogenic signalling with FIR garments—mechanisms tied to ATP production, vascular adaptation and long‑term tissue support.
5. Lower physiological cost in steady work
Sport physiology research has observed reduced oxygen cost (VO₂) at submaximal intensities when wearing FIR apparel, indicating greater efficiency at a given pace—useful in back‑to‑back sessions and blocks.
6. Thermal comfort & moisture management
The fabric’s knit structure balances breathability and thermoregulation, helping stabilise micro‑temperature during cool‑downs and travel, while wicking moisture away from the skin.


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.
