What is Recovery Sleepwear?


Have you ever thought, “I wonder if there are pajamas that could make me a better athlete?” If you said no then you fall into the 99 percentile of people who have never heard of recovery sleepwear, and yes, I said pajamas. At the beginning of 2017 Under Armor launched a brand new product, “Athlete Recovery Sleepwear, inspired by TB12”, that claimed to promote better sleep, and help your body recover faster. This new innovation claims to harness the power and benefits of FIR.

What is FIR (Far Infrared Radiation)?

It common for most people to assume that radiation is a bad thing, but not all radiation is. Far infrared is a form of radiation felt as heat to the human body. FIR is absorbed by our human bodies, but is also released by our bodies in a form called “black body radiation”. FIR is produced by the sun and is classified as being one of the three divisions in the infrared radiation band. Those divisions pricey as Near Infrared, Mid Infrared, and Far Infrared. Among those FIR is the only one that transfers energy purely in the form of heat.

Different Types of FIR Recovery

When describing the benefits of FIR it must be first understood that FIR can be applied in two ways. The first recovery method for FIR is, “Heating FIR”: implemented with the use of heat lamps or saunas. The second method of recovery is “Non-Heating FIR”: implemented by weaving FIR emitting nanoparticles and microparticles into a fabric. This is the method used in Athlete Recovery Sleepwear. Both of these methods have very similar benefits but retain slight differences.

Benefits of fabric woven FIR (Athlete Sleepwear)

Although the benefits of fabric woven FIR are still in early stages of development, what little research has been done can give us a basic understanding of this fairly new technology. Through various studies, FIR has appeared to display benefits such as:

  • Reducing inflammation caused by arthritis
  • Lowering of body fat
  • Enhancing sleep quality
  • Increasing blood flow
  • Acceleration in developing ATP (energy)
  • Improvement of oxygen consumption
  • Promoting long term healing, anti-inflammatory aid, and pain relief.
  • Reduces time-consuming recovery sessions


After reading numerous reviews on this product it seems as though the common response to the sleepwear is very good. Most of the reviews claimed to notice several benefits from the sleepwear, after being worn for the first week. Surprisingly one of the most frequent praises of the sleepwear was their comfort, some even claiming that they were the most comfortable pajamas they’ve ever worn.


After scanning the reviews and studying the research these pajamas seem like a great buy, the only con I can find in buying these pajamas is the price. Ringing up around $100 dollars these pajamas come in on the pricey side. Although I myself have not been able to try out these fancy pajamas it seems as though the advantages are promising, and if you are a dedicated athlete, looking for ways to enhance your recovery this appears as a great way to do just that.
