The Science of Celliant Simplified

We often hear questions from Celliant users curious about what our apparel is doing to influence the physiology of their bodies.  We’ve asked Dr. Michael Coyle to explain the science behind Celliant in the simplest possible terms in our third conversation with Celliant’s Chief Science Officer:

“The Celliant story starts with the heart. The heart pumps blood through tubes called blood vessels. Blood vessels vary in size, getting smaller the farther away from the heart that they go. In fact, they get extremely small. Interestingly, some blood vessels can relax or tighten (i.e. vasodilate or vasoconstrict) depending on certain physiological conditions; these vessels open and close depending on how much blood needs to go to whichever muscle or muscle group is active. What controls whether they are open or closed? All kinds of chemicals control whether the smallest blood vessels, called capillaries, open or close. For example, exercise is a signal that more blood needs to come to a muscle. Light energy, too, is something that can cause the capillaries to relax.”


“The type of light that can cause the capillaries to open is light that we cannot see. The spectrum of light that the eye can see is only a small band within the entire light spectrum, but there is also a whole spectrum of invisible light, from infrared to ultraviolet. This light that we cannot see, specifically infrared (IR) light, can penetrate into the skin and cause capillaries to open up, which means that more blood flow can come to the skin and tissue under the skin. This has some major benefits. For example, increased blood flow to a wound or a cut would make it heal faster.”


The primary tenet of Celliant products, explains Dr. Coyle, focuses on utilizing these properties of light to enhance blood flow.

“What does that mean?” he continues. “Instead of wearing a Band-Aid, you could wear a bandage made of Celliant that increases blood flow and helps the wound heal faster. That’s what Celliant does.”

“Inside the fabric, there are several minerals that are ground up more finely than the human eye can see. The minerals within the yarns reflect the light (that you can’t see) back into the skin, interacting with the capillaries and causing them to relax or open.  This process allows greater blood flow to that area.”

This, of course, is only a basic version of the work Celliant is doing for your body, even on a microscopic level.  What other questions do you have?  What else can we clarify?  Tweet us your questions @Celliant.
