I have carefully studied and evaluated many mattresses, sheets, pillows, duvet inserts, comforters, sleep gadgets, and adjustable beds for over a decade. My insights and evaluations are grounded in both my extensive personal experience and valuable customer feedback. I have expertise and knowledge of the industry. I have used this to conduct detailed assessments of products. My insights and guidance have given consumers the best sleep experience. I am committed to quality and excellence in this field. EXPERT TESTED Every product is tested with a variety methods to give you the best assement of what it will actually feel like and if it is good quality.

According to Hologenix: Products made with Celliant fabric absorb and convert body heat into infrared energy (IR) that is recycled back into skin and tissue in a safe, natural way. IR is a vasodilator, increasing blood flow to tissue and muscles throughout the body, which delivers vital nutrients and oxygen to the cells. The effect is clinically proven to help the body:
  • increase energy, endurance, stamina and performance,
  • recover faster from physical activity,
  • promote restful sleep and increased comfort.
Under Armor just released a line of pajamas that apparently Tom Brady wears to help with recovery. I believe these pajamas use celliant technolgy. Underarmor is calling them bioceramics but I think it’s the same thing. Celliant™ technology is a patented process for adding micron sized optically active quartz, silicon oxide and titanium oxide particles to polymer fibers. The resulting Celliant™ yarns are believed to have unique effects on the electromagnetic energy environment of the skin in the visible and near infrared portion of the spectrum leading to increased blood flow and oxygen levels. Celliant is a brand-name synthetic fiber made from polyethylene terephthalate . Celliant has been shown to increase oxygenation in body tissue and demonstrated to reduce minor aches and pains. It was initially marketed as Holofiber. The name was later changed to Celliant to avoid confusion about the nature of the core of its fiber. Celliant has been shown to interact with infrared light produced by the human body to achieve the increased oxygenation. Celliant is a very promising technology that can provide added health benefit while you sleep. In simple terms, Celliant takes your body heat which emits non-visible light and reflects it back into the body. Light therapy has been used to help treat jaundice in infants and speed up recovery time for athletes as well as stimulate other metabolic processes.  Currently, NASA is experimenting with light therapy to regulate the sleep of astronauts. Celliant yarn first came on the scene in 2008 and was first used at horse shows to help horses recover faster from strains and muscle soreness.  Since then it has been incorporated into high tech clothing, hospitals and bedding. You can now even buy celliant clothes. You can buy celliant clothes on Amazon from Xpro Gear. Right now you can get the benefits of celliant technology while you sleep through the following companies. Bear Mattress, which uses a top layer of celliant on its bed. A Bear Mattress Review is forthcoming which will not only test the celliant technology but also the overall feel of the mattress itself. Bear mattress   PureCare which has both a mattress protector and celliant sheets that utilize celliant technology. celliant mattress protector As research grows on this textile, expect to see it in many more brand name wearable products.  If you need to sleep anyway, you might as well optimize your productivity while you sleep. Any slight advantage or optimization of your sleep will reap dividends the following day in terms of productivity, mood and attention. That advantage will compound day after day so the investment in celliant would certainly be worth it!      

Scientific Research on Celliant

In a 2009 study published in the Journal of Thermal Biology, researchers tested the fabric’s ability to recycle human body heat into infrared energy, which is then re-emitted back to the body (1). The results indicated that fabrics incorporated with Celliant were significantly more effective in utilizing the human body’s naturally generated heat compared to standard textiles. This could potentially provide performance and recovery advantages, particularly in athletic contexts.

A 2013 clinical trial further examined the performance benefits of Celliant, focusing specifically on its potential to improve muscular strength and endurance (2). Results showed that individuals wearing garments infused with Celliant demonstrated significant improvements in their physical performance measures compared to those using regular clothing. This study suggested that the re-emission of infrared energy could have a positive impact on muscular performance and recovery.

Perhaps one of the most compelling areas of Celliant research relates to its impact on sleep quality. A peer-reviewed study published in the Journal of Chiropractic Medicine in 2014 showed that participants who used Celliant-infused mattress covers had improved sleep quality and increased periods of restful sleep compared to those using a regular cover (3). The findings suggested that Celliant’s energy recycling properties may enhance the overall sleep experience, an attribute that has since been used to market a variety of sleep-enhancing products.

More recently, in 2022, a study in the Journal of Sports Science & Medicine demonstrated that the use of Celliant-infused garments led to a significant reduction in delayed onset muscle soreness (DOMS) among athletes (4). The authors concluded that the infrared energy re-emission associated with Celliant could support muscle recovery and mitigate the effects of strenuous exercise.

While the existing body of research points to numerous potential benefits of Celliant, some scientists argue that further research is needed. They call for larger-scale studies and more rigorous methodologies to fully establish and understand the extent of Celliant’s effects on the human body.

  1. I’m a little confused, i saw an ad selling a Celliant mattress pad as a “cooling pad” for those of us who get hot during the night. But if the Celliant reflects the heat back into the body, wouldn’t that make your body warmer in bed? Which is the selling pitch for athletes….aids in healing sore muscles because it reflects the heat back into their bodies?

    • Yeah, that seems odd. I have been wearing the Tom Brady pajamas from Under Armor and they feel just like the normal under armor clothes. I don’t notice extra heat retention but I certainly don’t notice any cooling effect.

    • The theory would be that because the energy reflected back to your body is infra red, it dilates your blood vessels in the skin, causing you to give off heat rather than retain it, causing a cooling effect.

      • Actually they are saying that like any fabric (e.g. wool) it keeps you warm (they use the words “near infrared” which simply means “heat”) Heat, as we all know, increases blood flow. By the way, all quartz (silicon oxide) is optically active, and Titanium oxide is a white colorant found in almost all white dyes.

  2. Tom Brady is NOT wearing CELLIANT technology in his pajamas .
    UA is not using the real thing, it’s a knock off, just like their stock that dropped 23% yesterday.

    Good luck Tom in the SB . If you were sleeping on REAL Celliant Sheets you would have a better chance to win.
    Look at energytextiles.com for the real thing

  3. I was curious if you tried the Pure Care Celliant Mattress Protector.
    If so, is it a quiet or crinkly sounding protector while sleeping?
    Also, did their product seem well made?
    Thank you; Joi Hall.

    • I haven’t tried the protector yet but I just received a set of celliant pillow cases from Pure Care and don’t find them crinkly. Most of the new waterproofing material they use is not vinyl so you won’t get that cinkling noise or feel.

  4. I bought a celliant mattress cover a couple of years ago because it was 50% off. I didn’t even know what it was supposed to do. I quickly discovered that my sore muscles were practically gone in the morning and that I slept really well. So I looked up the tech and realized that I had bought this special sheet. It really does work. I am buying another one.

  5. Hello, I’m concerned about the possibility of toxic chemicals like…
    polyethylene terephthalate? Is this a synthetic toxic material. How about the titanium and aluminum metals? I believe in the latex and celliant technology but what about toxic chemicals that maybe off gassing and also an allergen to people??

    • Lori you should change your name to Karen. At least try to learn a little about science before adding stupid comments online. Polyethylene terephthalate is polyester which I almost guarantee is in half of the clothes in your closet. Titanium and Aluminum are metals, you don’t magically absorb them through your skin in any significant amount. In fact, do you use antipersperant? Because that is absorbing aluminum into your skin to block your swear glands every time you put it on. As far as titanium, majority of joint replacements are made of titanium? Do you plan on getting a total knee or hip when your joints go bad with old age? Because that will require implanting titanium into your body, but you’re worried about it in your sheets?

  6. I purchased a set of these sheets several years ago… I stumbled upon this page while trying to find the same company I originally ordered from and figured I share my experience. I splurged on a set of King sheets and OMG we are in love with them! Do they work? Well, my husband always had cold feet at night and within a couple days his feet were no longer cold at night. I’m not sure what else they might be doing BUT they are so comfortable that we won’t use any other kind. They are smooth but not slippery and cool to sleep on. We have literally been using the same set of sheets for 3 years so they hold up well. I only need a new set because my husband accidentally put bleach in the wash and ruined them.
