HEAL SMART YARNS™ offers a natural, effective, and safe solution for internal healing.

Founded by Science of Apparel’s Roberto Crivello, HEAL SMART YARNS™ is a platform of advanced infrared yarn technologies designed to promote health and wellness through textile innovation. These yarns harness and convert the body’s natural heat into beneficial infrared energy, including Far Infrared (FIR), which is reflected to enhance blood flow, oxygenation, and recovery through a process called biomodulation.

The platform supports a range of infrared yarn solutions, each engineered to meet specific performance, comfort, and wellness goals across activewear, bedding, therapeutic garments, and everyday apparel.

Why Infrared Yarns Are Safe

Passive Emission from Body Heat

Most infrared yarns, including those in HEAL SMART YARNS™, work by absorbing the body’s natural heat and re-emitting it as infrared energy, especially Far Infrared (FIR). There’s no electricity, radiation, or external power involved, making the process inherently safe and non-invasive.

Far Infrared (FIR) is Biocompatible

FIR is a non-ionizing form of energy, meaning it doesn’t damage DNA or cells. It has been used safely for decades in medical therapies, saunas, and recovery products to promote circulation, reduce inflammation, and aid in healing.

No Chemicals or Additives (in many cases)

When infrared properties are embedded at the fiber or yarn level using specialized materials (like ceramics or other FIR-emitting particles), they don’t require topical coatings or chemical treatments, further enhancing safety and durability.

Regulatory Alignment

FIR textiles have been studied and used in regulated markets, such as medical textiles, sports science, and sleep technology, often under standards set by ISO or FDA (for specific claims), or textile safety certifications like OEKO-TEX, ensuring biocompatibility and non-toxicity.

🚫 What to Be Cautious About (Generally Speaking)

Quality of Materials: Not all infrared yarns are equal. Inferior products may use fillers or treatments that degrade over time or may not be tested for long-term skin contact.

Unsupported Health Claims: Safety isn’t the same as efficacy. Products should avoid making unverified medical claims unless they are backed by clinical validation.

Infrared yarns work by capturing body heat and converting it into infrared energy, particularly Far Infrared Radiation (FIR), which is then re-emitted back into the body. This process is passive, safe, and continuous, making it highly suitable for integration into wearable textiles.

Mechanism of Action

Body Emits Heat (Infrared Radiation)

The human body constantly radiates heat, much of it in the infrared spectrum. Infrared yarns are designed to interact with this natural process.

Infrared-Responsive Materials Embedded in the Yarn

The yarns are infused or constructed with infrared-emitting agents such as:

Bioceramics

Mineral oxides

Specialty polymers

These materials can absorb heat energy from the body and re-radiate it as FIR.

Re-Emission of FIR into the Skin and Tissue

The yarns emit Far Infrared Radiation (wavelengths typically 4–20 μm) back into the body.

FIR penetrates the skin and interacts with water molecules and cellular structures.

Biomodulation Begins

This triggers physiological effects known as biomodulation, such as:

Vasodilation (expansion of blood vessels)

Improved microcirculation

Increased oxygen delivery

Enhanced cellular repair and recovery

Currently, the team at HEAL SMART YARNS™ can supply custom orders of knit and woven yarns, fabrics, or finished products with very low minimums or unlimited capacity according to industry standards.

Infrared energy is part of the electromagnetic spectrum and is divided into three categories based on wavelength: near-infrared (NIR), mid-infrared (MIR), and Far-Infrared (FIR). Each type has unique properties and applications:

Near Infrared Rays

-  Short in length

-  Surface level

-  Closest to visible light

-  About 0.7 - 1.1 microns

-  No warmth

-  Used in remote control devices

-  Improve skin health

-  Accelerates wound healing

Mid Infrared Rays

-  Average in length

-  Targets deeper layers

-  Used for thermal imaging

-  About 3 - 5 microns

-  Improving circulation

-  Aiding muscle recovery

Far Infrared Rays

-  Long in length

-  Penetrates even deeper

-  Closest to microwaves

-  About 7 - 14 microns

-  Emits thermal energy

-  Used in saunas and fabrics

-  Easily absorbed by the body

- Provides overall therapeutic effects such as pain relief and detoxification

Far Infrared Rays (FIR) are the most beneficial for health and wellness because the human body readily absorbs their wavelength (7-14 microns). FIR energy can penetrate the skin and tissues to improve circulation, boost oxygenation, and promote recovery.

No. HEAL SMART YARNS™ technologies are noninvasive and safe.

As a platform of advanced infrared yarns, HEAL SMART YARNS integrates multiple FIR-based textile technologies designed to support the body’s natural healing processes without introducing risk. Infrared textile products, including those utilizing Far Infrared (FIR), are classified by the FDA as nonsignificant risk and do not require warning labels—even for infants, nursing mothers, or expectant mothers.

There are no known side effects associated with using these yarns. Some users may experience a gentle warming sensation, which is a normal response to improved circulation and a sign that the infrared technology is active. As with any wellness product, we recommend consulting a healthcare professional if you have specific medical conditions or concerns.

No. The particles are permanently embedded in the fibers of HEAL SMART YARNS™, ensuring that the far-infrared benefits remain effective throughout the product's life, even after frequent washing and long-term use.

Far Infrared energy emitted from clay silicates and minerals was accidentally discovered in 1970 at an ancient ceramic factory in China. Medical tests of some workers showed significantly better levels of health than expected, even though they were working in what was considered mucky and "poor" conditions.

Tests of the muddy clays around the factory revealed high levels of the 33 essential minerals the human body needs. Specific combinations of these minerals were shown to emit far-infrared energy waves, which led to further exploration of their health and wellness applications.

Yes. HEAL SMART YARNS™ products should be worn directly with your skin for optimal results. The closer the fibers are to your body, the more effective the FIR energy emission will be.

Yes! HEAL SMART YARNS™ technology is powered by your body’s natural heat, so it works as effectively in the dark.

Currently, our products are not universally covered by insurance. However, some customers have successfully submitted claims for reimbursement. Check with your insurance provider for more details.

Biomodulation is a process that modifies biological processes using light or other low-energy stimuli. It can be used for medical, aesthetic, and lifestyle purposes. Light penetrates the skin and mitochondria of cells, stimulating chemical reactions that restore cellular function. 

Biomodulation can treat or manage conditions like arthritis, chronic fatigue syndrome, sports injuries, and burns. 

Biomodulation can improve skin texture and health by promoting collagen and elastin production. 

Biomodulation can help athletes recover from injuries like hamstring pulls, plantar fasciitis, and muscular sprains. 

Biomodulation may help prevent neurodegenerative disorders like Alzheimer's, Parkinson's, and Motor Neuron Disease. 

Biomodulation is also known as photobiomodulation (PBM), which is a combination of the words "photo" (light), "bio" (life), and "modulation" (change). 

HEAL SMART YARNS™ Is 100% Natural, Safe, and Non-Invasive.It is the Application of Red or Near-Infrared Wavelengths Over Diseased Areas, Injuries, Sores, or Wounds to Promote Healing and Reduce Inflammation and Pain.

Multiple peer-reviewed studies and positive user testimonials have validated the effectiveness and safety of HEAL SMART YARNS. Users reported significant improvements in conditions such as neuropathy, plantar fasciitis, and recovery from surgeries without mentioning any adverse side effects. 

Numerous published studies showcase the significant benefits of FIR light therapy, also known as photobiomodulation, on cellular health and function. This body of research supports the practical advantages provided by HEAL SMART YARNS™.
