KYMIRA infrared garments consistently demonstrate increases in Nitric Oxide and local oxygenation (tcP0@), as Nitric oxide acts as a vasodilator, relaxing and widening blood vessels.

This has numerous benefits from increasing the volume of oxygen and nutrient rich blood to our muscle cells, to accelerating the rate at which waste products, like lactic acid and other fatiguing and inflammatory metabolites are transported away from them. This supports reducing swelling during inflammatory responses, reduces stiffness and DOMS.

(Gordon et al, 2019).

In randomized double blind repeated measures studies, KYMIRA® products increased tissue oxygen levels (tcP02) by 20% on average, compared against a host of control garments that used standard fabrics and/or compression. This increase was a building increase that both peaked and maintained after 70-90 minutes of continuously wearing the KYMIRA® products. 

(Gordon et al, 2019).

The chemical unit of energy that powers our cells is Adenosine Triphosphate (ATP). When you wear KYMIRA® Infrared products, the infrared activates a molecule called Cytochrome C-Oxidase, a transmembrane protein in our mitochondria which mediates the production of ATP. Mitochondria are the power plants of our cells, where ATP is produced, and Cytochrome C-Oxidase is one of the gateways that allow workers through the power plant. By opening the gateway, ATP production is increased, and your cells have more fuel and energy. Practically, this translates to higher work output, improved neuromuscular efficiency, and better power‑endurance.

Nitric oxide also supports muscle contraction and glucose uptake, which improves muscle velocity and power output.

(Quirk, 2020, Worobets et al, 2015).

Studies observe a reduced oxygen cost at matched workloads and faster activation of aerobic pathways— meaning output performances at the same intensity with less physiological required effort. This allows athletes to sustain effort with less physiological strain and improved endurance performance.

(Worobets, 2015).

Neuromuscular recovery improves significantly with KYMIRA Infrared technology. Clinical trials show enhanced countermovement-jump (CMJ) height, faster take-off velocity, and higher modified Reactive Strength Index (mRSI) at 24–48 hours post-exercise compared to placebo. These benefits indicate accelerated restoration of explosive strength, neuromuscular efficiency, and joint stability, supporting quicker recovery and readiness for subsequent performance bouts.

[Lever et al., 2025].

Nitric Oxide has been well documented to cause skeletal muscle tissue relaxation that enhances joint motion and muscle elasticity. These in turn, are both shown to assist in athletic warm-up and lower acute soft-tissue injury risk.

Wearing KYMIRA infrared garments 30–90 minutes pre‑session is shown to prime tissues for high‑velocity and eccentric
demands.
(Lever et al, 2025).

Studies show KYMIRA Infrared technology can significantly improve functional strength. Healthy adults experienced about a 12% increase in grip strength after just 90 minutes of wear, while individuals with chronic wrist and elbow pain saw a 16.8% improvement over two weeks. These benefits are linked to enhanced blood flow, oxygen delivery, and neuromuscular efficiency through increased nitric oxide activity.

(Gordon et al, 2021).

Short Term

Infrared exposure activates the Cyclic Guanosine Monophosphate pathway (cGMP) downstream of Nitric Oxide, inhibiting the nociceptive signalling in pain receptors and alleviating pain while wearing KYMIRA infrared.

Longer Term 

Utilising KYMIRA infrared products for 48 hours after athletic exertion to exhaustion, showed a significant perceived reduction in DOMS at 24 hours, compared to the control.  

Once our products are removed, DOMS does not return, and this is believed to be because exercising in KYMIRA® Infrared products reduces the physiological causes of the DOMS itself such as reducing micro muscle tears and speeding up their healing.

(Gordon et al 2021, Gonzalez et al, 2025).

Nitric oxide acts as a powerful antioxidant, neutralising free radicals and promoting the formation of glutathione, which helps reduce inflammation and oxidative stress post-exercise. As a vasodilator, nitric oxide also promotes accelerated blood circulation, accelerating the rate at which waste products and pro-inflammatory mediators, like lactic acid, are transported away.

Clinical and preclinical research shows reductions in inflammatory and immunoregulatory markers and improved symptom profiles for musculoskeletal stress and induced arthritis models.

(Djuretic et al, 2021).

KYMIRA infrared fabrics warm faster and retain heat longer in cold conditions (+63%), while drying markedly quicker (+65%) in heat, complemented by circulatory improvements for effective thermoregulation, and heat distribution.
KYMIRA Infrared products help to regulate temperature in a different way to standard clothing. Due to the enhanced circulation and oxygenation, this supports the body to efficiently transport and distribute heat, or promote cooling, to all areas, resulting in a regulating effect.

Our customers wear KYMIRA base layers in all-weather environments and the products have been used to great effect to regulate in temperatures ranging from -35 to +48 degrees (Celsius). 

Increasing nitric oxide (NO) supports altitude adaptation by counteracting the natural decline in NO levels under low-oxygen conditions. At high altitude, NO promotes vasodilation—widening blood vessels—to enhance oxygen delivery. This effect is driven by the NO → sGC → cGMP pathway, which plays a critical role in maintaining vascular function and microcirculation.

Our technology contains the mineral Quarts Dioxide. This is not included for infrared purposes, but rather its ability to absorb shorter wavelengths of UV light which is harmful to us. Once absorbed, it converts UV into a longer wavelength which is then more harmful to microbes. This dual effect gives our products a minimum rating of SPF 35, and a natural antimicrobial effect to keep you fresh.
