How Does Infrared Energy Impact TcPO2?

Can you improve your health and performance naturally by understanding TcPO2 and harnessing the power of infrared energy? In this article, we will explore TcPO2 and why it’s important, the synergy between TcPO2 and infrared energy, as well as how to incorporate infrared light therapy into your daily life, including bio-responsive fabrics featuring CELLIANT® infrared technology. 

What is transcutaneous oximetry (TcPO2)?

Transcutaneous oximetry (TcPO2) is a non-invasive diagnostic method used to measure the oxygen level (partial pressure) in the tissue beneath the skin. TcPO2 involves placing sensors on the skin’s surface to assess the oxygenation status of these tissues, which plays a key role in our overall health and well-being.  

By attaching a small sensor to the skin, typically on the arm or leg, TcPO2 monitors can provide real-time data on how well oxygen is being delivered and utilized in specific areas of the body. This process is particularly important for individuals looking to optimize their physical performance, as well as for those seeking to increase blood flow. Understanding your body’s TcPO2 levels can also be a vital step in enhancing recovery from physical fatigue, helping to ensure your tissues are functioning as optimally as possible. TcPO2 is a powerful tool in the health enthusiast’s toolkit, offering a window into the body’s intricate oxygen distribution system without the need for invasive procedures. 


TcPO2, or transcutaneous partial pressure of oxygen, is a versatile diagnostic tool with applications extending beyond traditional medical uses. While it is known for its role in assessing tissue oxygenation in patients with vascular conditions, TcPO2 is also making strides in the health and wellness sector and the world of athletics and sports. From medical diagnostics and patient care to fitness monitoring and performance optimization, TcPO2 provides valuable insights that drive innovation and efficacy across various fields. 


TcPO2 testing is commonly used in clinical or medical settings, including for: 


TcPO2 provides value in non-medical settings as well, such as for athletes and individuals interested in physical fitness or biohacking. Applications include:

Outside of medical and athletics contexts, TcPO2 has the potential to offer key insights relevant to industrial health and safety, aerospace and aviation, sleep research and more. There are even tools that help people track biomarkers like TcPO2 on their own, rather than needing to do it in a professional or clinical setting. The Moxy Monitor System, for example, is a battery-powered, super small sensor that measures oxygenation levels in muscle tissues to provide real-time physiological feedback.


There are environmental, physiological and lifestyle factors that can impact TcPO2, including: 

Additionally, external interventions can significantly affect TcPO2, such as infrared light therapy. Let’s take a closer look at infrared energy and how it interacts with TcPO2.

Exploring the Synergy Between Infrared Energy and TcPO2

Infrared energy, when applied to the skin, has a unique ability to enhance TcPO2 levels, creating a beneficial synergy for optimal tissue function. This process primarily occurs because infrared light increases local circulation and enhances cellular oxygenation, key factors in boosting TcPO2. 


Electromagnetic Light Spectrum

Infrared energy, or infrared light, forms part of the electromagnetic spectrum, just beyond red visible light. Infrared’s unique characteristic lies in its ability to penetrate deep into the body’s tissues, promoting a cascade of natural biological processes. The physiological benefits of infrared light therapy include: 

As noted, the increases in local circulation and cellular oxygenation derived from exposure to infrared light can play a role in boosting TcPO2. 


There are many ways to get the benefits of infrared energy in your daily life. One popular method is the use of infrared saunas. These saunas use infrared heaters to emit light, which is experienced as radiant heat and is absorbed directly into the human body. 

Additionally, clothing and bedding made from infrared fabrics can provide you with the benefits of infrared energy while you sleep or go about your day. These materials are designed to reflect the body’s heat in the form of infrared energy, so it can be absorbed into the skin, tissues and muscles. 

CELLIANT infrared technology is a wellness ingredient that can be embedded into (or printed on) fibers, yarns and fabrics to create bio-responsive textiles. These bio-responsive textiles harness all of the benefits of traditional infrared light therapy and incorporate them into the fabrics of our daily lives, from clothing and footwear, to upholstery and bedding, and more.


There is a vast existing body of research on infrared energy and how it impacts the body, as innovators and scientists have been exploring the effects on infrared light throughout history. As leaders in infrared technology, the CELLIANT team continues to work in tandem with our Science Advisory Board to investigate the benefits of CELLIANT, including how it interacts with TcPO2. To date, there are 10 peer-reviewed, published studies that collectively demonstrate the efficacy of CELLIANT infrared technology. Several of these clinical trials have TcPO2 as a key endpoint: 

We’re committed to expanding our body of research and embarking on further clinical trials to further validate the science behind CELLIANT infrared technology.
