The Science of Fabric Frequency
Why what you wear matters more than you think
The Research
In 2003, Dr. Heidi Yellen conducted groundbreaking research measuring the bioenergetic frequencies of different fabrics using the Ag-Environ machine, a device originally developed to measure the energy of foods and their effect on the human body.
Her discovery was revolutionary: certain natural fibers resonate at 5,000 Hz—a frequency that promotes healing and regeneration in human tissue. The human body at rest maintains a baseline frequency of approximately 100 Hz, while diseased tissue measures at just 15 Hz.
What we discovered is that the fabrics touching our skin all day, every day, profoundly affect our energetic state. Wearing healing-tier fabrics elevates our frequency. Wearing synthetics depletes it.

Healing Tier Fabrics
Linen
The most powerful healing fabric. Linen is naturally antibacterial and promotes tissue regeneration. It has the highest infrared reflection of any natural fiber, making it uniquely effective at promoting healing energy.
Note: Linen energy flows left-to-right. Never blend or layer with wool (which flows right-to-left), as the opposing flows cancel to 0 Hz.
Wool
Grounding, protective, and thermoregulating. Wool provides exceptional insulation while maintaining 5,000 Hz healing frequency. Ideal for winter layering and cold-weather protection.
Cashmere
Promotes relaxation and emotional stability. The luxurious softness of cashmere isn't just about comfort—it's about maintaining a high-frequency state that supports mental and emotional well-being.
Silk
Spiritual protection and purity. When unprocessed, silk can measure between 5,000-10,000 Hz—the highest of any natural fiber. It's hypoallergenic and has been revered for millennia as a sacred fabric.
Natural Fur
Shares the same biological origin as wool and cashmere, maintaining 5,000 Hz. When ethically sourced and properly cared for, natural fur can last 50+ years, making it one of the most sustainable luxury materials available.
The Linen + Wool Rule
Ancient wisdom meets modern science: linen and wool must never be worn together.
Linen's energy flows left-to-right. Wool's energy flows right-to-left. When combined, these opposing flows cancel each other completely, reducing the combined frequency to 0 Hz.
This prohibition appears in Deuteronomy 22:11 as shatnez—the ancient Hebrew term for forbidden mixtures. What seemed like religious law was actually energetic wisdom.
Our AI styling system automatically prevents linen and wool from being paired in your wardrobe.
Foundation Tier
Organic Cotton
Matches the human body's baseline frequency of 100 Hz. Organic cotton doesn't elevate your frequency like healing-tier fabrics, but it doesn't deplete it either. It's the perfect foundation for everyday basics—breathable, comfortable, and energetically neutral.
Hemp
Durable and sustainable at 100 Hz. Hemp is naturally antibacterial, UV resistant, and becomes softer with each wash. It's one of the most environmentally friendly fabrics available while maintaining neutral frequency.
