Wait until you hear about The Frequency of Clothing.
Have you ever stopped to think about what your clothes are doing besides keeping you warm, making you comfortable or, hopefully, making you look good?
I hadn’t given much thought to it either.
Then I started reading about The Frequency of Clothing and the work attributed to Dr. Heidi Yellen. Suddenly, that shirt, those sheets and even the towels hanging in the bathroom became a little more interesting.
The idea is fascinating: different fabrics have been reported to carry very different vibrational measurements. Natural fibers such as linen, wool and organic cotton are associated with some of the highest measurements, while many synthetic fabrics appear at the other end of the scale.
And that made me curious.
Could the fabrics we put against our bodies every day matter in ways we’ve never considered?
Let’s take a look.
What Does “THE FREQUENCY OF CLOTHING” Actually Mean?
Everything around us is made of atoms, and atoms are constantly in motion. The word frequency generally describes how often something repeats or vibrates within a given period of time.
That basic scientific concept is well established.
The more unusual question is whether different fabrics possess measurable energetic characteristics that can meaningfully interact with the human body.
That’s where the work attributed to Dr. Heidi Yellen becomes particularly interesting.
Dr. Heidi Yellen and the Fabric Frequency Study
Accounts of Dr. Yellen’s work describe research conducted around 2003 involving the energetic measurements of different fabrics. The numbers attributed to that work have since traveled all over the Internet. And when you see them, you’ll understand why.
A healthy human body at rest was reportedly assigned a measurement of approximately 100. Different fabrics were then reported at dramatically different levels. Among the commonly reported results:
Linen — 5,000
Wool — 5,000
Organic Cotton — 100
Conventional Cotton — approximately 70
Silk — approximately 10–15
Rayon and synthetic materials — very low measurements, depending upon the fabric/material and those test results
Now, here’s something I think you should know.
I’ve found many articles repeating these results, but I have not found the original study by Dr. Yelllen in a peer-reviewed scientific journal or academic archive. Even the descriptions of how the measurements were recorded are not always consistent.
Does that mean we simply dismiss the whole subject?
I don’t think so.
It means we remain curious, keep asking questions and understand that these are findings attributed to Dr. Yellen’s work.
And frankly, the questions themselves are fascinating enough to keep me reading and researching.
Linen: The Standout in This Story.
Of all the fabrics associated with Dr. Yellen’s work, linen certainly gets your attention.
Linen is reported at a measurement of 5,000, compared with the approximately 100 attributed to a healthy human body at rest.
That’s quite a difference.
Linen is also one of the oldest textiles in human history. For centuries it has been used for clothing, bedding, bandages and household fabrics. It’s breathable, durable, absorbent and comfortable in warm climates—which is one reason linen clothing has such a long history in hot and desert regions.
If we’re going to talk about linen’s long history in hot climates, we might as well take a little visual trip while we’re doing it.
The next time you pick up a linen shirt, tablecloth or set of sheets, you may look at it a little differently.
I know I do.
Wool: Another Reported High-Frequency Fabric.
Wool is also commonly reported at a frequency of 5,000 in accounts of Dr. Yellen’s research.
We already know why humans have valued wool for centuries. It provides warmth, insulation and durability and can help regulate temperature.
But here’s an unusual twist to the frequency story.
Some discussions claim that linen and wool should not be worn together because their energetic effects cancel one another. This idea is sometimes connected with the Biblical instruction in Deuteronomy 22:11 concerning clothing woven from wool and linen together.
That’s certainly an interesting historical connection, but the Biblical passage itself doesn’t establish a scientific explanation involving fabric frequencies. The two ideas should not be confused.
It does, however, make for a fascinating question: “Why were people thinking about combinations of fabrics thousands of years ago?”
Organic Cotton: Closer to the Reported Human Number.
Cotton is probably much more familiar in our closets and dresser drawers.
Accounts of Dr. Yellen’s work commonly place organic cotton at approximately 100, which those same accounts compare with the reported frequency value of a healthy human body at rest.
Conventional cotton is often listed lower, at approximately 70. Why the reported difference?
Some advocates suggest agricultural practices, chemical treatments and processing could play a role. However, without the original research methodology, we can’t confidently say what caused the difference—or even how those particular values were established.
What we can do is pay attention to what we’re buying. If you prefer natural fibers, checking the tag for 100% cotton or certified organic cotton is a simple place to start.
What About Hemp?
Hemp frequently appears on modern lists of “high-frequency fabrics.”
Here’s where our detective work paid off.
I haven’t found reliable evidence showing that Dr. Yellen herself tested hemp as part of the work from which these famous fabric numbers originated.
That doesn’t make hemp a bad fabric. Hemp has plenty of interesting qualities of its own. It simply means we shouldn’t put a number beside hemp and tell you Dr. Yellen measured it when we can’t establish that she did.
Sometimes knowing what we don’t know is just as important.
Silk, Rayon and Synthetic Fabrics.
This is where the online versions of the story become particularly inconsistent.
Silk is generally assigned a relatively low number in retellings of the research, although the exact value varies.
Rayon is another problem. Some sources describe it as low frequency, while others have placed it among supposedly beneficial fabrics.
Synthetic materials such as polyester, acrylic and nylon are commonly reported at or near the bottom of the scale.
Does that mean wearing polyester will make you sick? We don’t have good scientific evidence to make that claim. And please don’t frighten yourself every time you discover polyester on a clothing label.
Instead, this information can encourage us to become more curious about the materials that surround us every day.
Take a Look at What’s Touching You Every Day:
This may be my favorite practical lesson from the whole subject. Look around your house at:
- Your shirts.
- Your pajamas.
- Your sheets.
- Your towels.
- Your blankets.
- The chair you’re sitting on.
We spend enormous amounts of time in contact with fabrics, yet most of us rarely look at what they’re actually made from.
You don’t need to throw everything away and replace your entire wardrobe with linen tomorrow!
Instead, start reading Contents labels, which you may already do to find out the laundering instructions.
Maybe the next time you replace your sheets, you choose cotton or linen.
Maybe your next summer shirt will be linen rather than polyester.
Maybe you simply begin paying attention.
The more we understand about what surrounds us, the more intentional our choices can become.
We Live in a World Full of Frequencies.
Clothing is only one reason this subject caught my attention.
Our modern environment includes Wi-Fi, cellular communications, Bluetooth devices, household electronics and countless other sources of electromagnetic energy that didn’t surround previous generations.
It’s important not to lump every type of “frequency” together as though they’re scientifically identical. The vibration of molecules in fabric and electromagnetic radiation from wireless technology are very different physical phenomena.
But both subjects raise a broader question I think is worth asking: How aware are we of the environment we’re creating around ourselves? That is a question a worth finding answers to.
Could a tuün® RESONATE Belong In Your Life?
I don’t believe we should make frightening claims about everyday technology—or promise that one product can protect us from every environmental influence.
What interests me about tuün® RESONATE is its place within the broader conversation about personal environment, frequency and the choices we make about what surrounds us.

The Frequency of Clothing Is Worth Thinking About.
For me, learning about fabric frequency isn’t about becoming afraid of my closet. It’s about becoming more aware of:
- What am I wearing?
- What am I sleeping on?
- What am I bringing into my home?
- What technology surrounds me?
- Are there simple choices I can make that better fit the way I want to live?
Do we have all the answers about fabric frequency? No.
The findings attributed to Dr. Heidi Yellen are fascinating, but the original research behind the widely repeated numbers is difficult to verify, and I think you deserve to know that.
At the same time, learning about this subject has made me much more conscious of something very simple: What touches my body every day deserves my attention.
Natural fibers such as linen, wool and cotton have been part of human life for centuries. Whether you’re interested in their comfort, breathability, sustainability, history—or the intriguing questions surrounding fabric frequency—there’s plenty of questions and ideas that are worth exploring.
So the next time you’re getting dressed, take a peek at that little tag you’ve probably ignored for years. You may never look at your closet quite the same way again.
