Contact Holistix promptly with your order information and, when useful, photographs or video showing the problem. Our team can review the issue and determine the appropriate next step under the applicable product and warranty terms.

Start with the product manual and our Holistix Quick Start Guides .

Product-specific instructions should take precedence over generalized recommendations found elsewhere online.

Follow the cleaning instructions for the specific product. Materials, electrical components, LEDs, heating elements, fabrics, gemstones, and electronic controls may require different care.

Do not assume that a cleaning method suitable for one Holistix device is appropriate for every device.

Travel rules depend on the product, battery type, airline, destination, and current transportation-security requirements. Check the specific product details and current carrier or security rules before traveling.

Some people use multiple wellness technologies, and some products combine more than one modality. Combination does not automatically establish either synergy or risk.

Evaluate each technology separately, follow each product's instructions, and avoid assuming that more simultaneous exposure is automatically better.

Consumer red-light devices use visible red wavelengths, often together with near-infrared wavelengths. In scientific and medical contexts, light-based biological effects are commonly discussed under photobiomodulation, or PBM.

The complete exposure depends on more than wavelength. Important variables can include irradiance, fluence, distance, area, timing, optical geometry, and device design.

660 nm is visible red light. 850 nm is near-infrared light and is invisible to the human eye.

Their optical behavior differs, but neither wavelength has one universal treatment depth or outcome. Device output, tissue properties, dose, geometry, distance, and the intended use all matter.

See 660 nm vs 850 nm .

There is no universal session length for every red-light device. Appropriate exposure depends on the actual device, irradiance, distance, treatment area, operating mode, intended use, and manufacturer instructions.

There is no universal frequency-of-use schedule that applies to every device or purpose. Follow the instructions supplied with your product rather than relying on a generic number of sessions per week.

No. Irradiance describes radiant power reaching an area. Device quality and appropriateness also depend on wavelength, coverage, uniformity, measurement conditions, geometry, timer controls, instructions, and intended use.

See What Is Irradiance?

Yes. Changing distance can change irradiance, illuminated area, uniformity, and exposure geometry.

See Red Light Therapy Distance: Why Inches Matter .

PEMF stands for pulsed electromagnetic field. PEMF devices generate time-varying electromagnetic or magnetic-field exposures.

Devices can differ in frequency, field strength, waveform, pulse characteristics, coil geometry, program design, and operating conditions.

No. Frequency is one technical parameter. The same frequency can be delivered under very different field strengths, waveforms, coil arrangements, pulse structures, and session conditions.

See What Does Hz Mean in PEMF? and the PEMF Frequency Index .

Do not assume that a higher setting is automatically better. Follow the product instructions and understand what the controls on your specific mat actually change.

See How to Read PEMF Mat Settings .

Electromagnetic interference can affect some active implanted devices. People with pacemakers, ICDs, neurostimulators, insulin pumps, cochlear implants, or other active electronic implants should not assume compatibility.

Follow the implanted-device manufacturer's guidance and obtain appropriate qualified guidance before using PEMF.

See the PEMF Safety Checklist .

PPB and PPM are concentration units. In hydrogen-water discussions they are commonly used to describe dissolved molecular-hydrogen concentration.

See What Does PPB Mean in Hydrogen Water? .

No universal therapeutic ladder has been established in which every increase in dissolved hydrogen concentration automatically produces a proportionally greater clinical effect.

Concentration is one exposure variable. Measurement method, water volume, generation conditions, retention, timing, and the specific research context also matter.

ORP means oxidation-reduction potential. It is an electrochemical measurement and is not a direct measurement of dissolved molecular hydrogen concentration.

See What Is ORP in Hydrogen Water? .

No. They use different approaches to producing or delivering dissolved molecular hydrogen. Useful comparison factors include concentration, water volume, generation or reaction conditions, portability, materials, measurement method, and timing.

See Hydrogen Water Bottle vs Hydrogen Tablets .

No. Red and NIR LED devices are generally interpreted as optical exposures using variables such as wavelength, irradiance, fluence, distance, and time.

Infrared saunas, blankets, and heat-oriented emitters are primarily evaluated through thermal variables such as temperature and exposure duration.

Compare them in the Red Light vs Infrared vs Near-Infrared Comparison Tool .

Terahertz radiation occupies a region of the electromagnetic spectrum between microwave and infrared frequencies. It is non-ionizing.

That physical classification does not by itself establish the safety, emitted spectrum, biological effect, or clinical effectiveness of a particular consumer device.

See the Complete Terahertz Frequency Guide .

Holistix does not use a blanket “healthy cells resonate at terahertz frequencies” explanation as an established mechanism for consumer devices.

Laboratory terahertz research and consumer wellness products should be distinguished according to the actual source, emitted output, measurement conditions, and evidence.

No. “Non-ionizing” describes the energy characteristics of the radiation. It does not mean every intensity, exposure duration, thermal condition, viewing condition, or device configuration is automatically safe.

No wellness device should be described as universally appropriate for every person and circumstance.

Follow the instructions, warnings, contraindications, operating limits, and safety information for the specific product.

Pregnancy precautions can differ by technology and product. Check the specific product labeling and seek qualified guidance when pregnancy is relevant.

Do not assume a consumer wellness device is appropriate for a child unless the product instructions specifically address pediatric use. Product-specific instructions and appropriately qualified guidance should control when age or medical circumstances are relevant.

A general FAQ cannot determine whether a particular device is appropriate for an individual medical condition.

Review the product-specific contraindications and warnings and obtain qualified medical guidance when appropriate.

Stop using the device if you experience an unexpected or concerning reaction and follow the product instructions.

Seek appropriate medical care for severe, persistent, or otherwise concerning symptoms.

Yes. Red and near-infrared light, PEMF, molecular hydrogen, infrared exposure, terahertz radiation, blue light, and negative ions have all appeared in scientific literature.

Evidence strength, device relevance, study design, exposure conditions, and clinical significance differ considerably among categories.

No. A study involving one product, wavelength, frequency, dose, concentration, field strength, or exposure protocol should not automatically be generalized to every device in the category.

No. Regulatory status belongs to a specific product, intended use, classification, authorization, clearance, or approval.

The regulatory status of one medical device does not automatically transfer to every consumer product using related technology.

We try to match the source to the claim. Scientific claims may require research literature, regulatory claims require appropriate regulatory sources, and product specifications may require manufacturer documentation or independent measurement.
