Frequently Asked Questions
Everything you need to know about frequency therapy, our devices, and how to order.
What is Schumann resonance and why does it matter for health?+
Schumann resonance is the natural electromagnetic resonance of the Earth's atmosphere, with a fundamental frequency of 7.83 Hz. This frequency has been present throughout the evolution of all life on Earth. Research suggests that human brainwave activity — particularly alpha and theta states — is closely correlated with the Schumann frequency range. Disruption of this natural electromagnetic environment (through urban living, indoor environments, and electronic pollution) is hypothesised to contribute to sleep disorders, stress, and reduced immune function.
Is frequency therapy scientifically proven?+
The field of bioelectromagnetics — the study of how electromagnetic fields interact with living tissue — is an active area of research with a substantial body of peer-reviewed literature. The therapeutic application of specific frequencies is supported by research in areas including sleep (delta and theta entrainment), pain management (alpha entrainment, 10 Hz), and cognitive performance (gamma, 40 Hz). The Schumann resonance hypothesis specifically has been studied in the context of circadian rhythm regulation. As with many emerging fields, the evidence base is growing but not yet conclusive for all claimed applications.
What conditions can frequency therapy help with?+
The Health Hertz guide contains protocols for over 40 conditions including insomnia, chronic stress and anxiety, pain and inflammation, cognitive fog and concentration, immune support, energy and fatigue, emotional regulation, and more. These protocols are based on published research and traditional practice. They are not medical treatments and should not replace professional medical care.
How long does it take to notice results from frequency therapy?+
This varies considerably between individuals and conditions. Many users report improved sleep quality within the first week of consistent use. Stress reduction effects are often noticed within a single session. Chronic conditions typically require consistent use over several weeks before meaningful changes are observed. The Health Hertz guide provides guidance on session duration and frequency for each protocol.
What is the difference between the Health Hertz Ripple and the Health Hertz Shimmer?+
The Health Hertz Ripple is the entry-level protocol device: 4 independent channels, up to 10 sequential frequency steps, a 100 mm onboard antenna, no built-in battery, USD $79.00. The Health Hertz Shimmer is the flagship: 8 independent channels, up to 25 sequential frequency steps, a 250 mm onboard antenna (6.25× the field coverage of the standard model), a built-in rechargeable battery for portable use, USD $249.00. Both devices support the full range of protocols in the Health Hertz guide.
Do the devices require an external antenna?+
No. Both the Health Hertz Ripple and Health Hertz Shimmer include built-in spiral coil antennas (100 mm and 250 mm respectively) and are fully functional without any additional accessories. External antennas (ANTSA01, ANTSB02, ANTSC03) are available as optional accessories for extended field coverage and are connected via the 3.5 mm output jacks.
What power supply do the devices use?+
Both devices are powered via USB-C at 5V DC — compatible with any standard USB-C charger or power bank. The Health Hertz Shimmer also has a built-in rechargeable battery for cordless operation. No special power supply is required. Both devices are compatible with Australian (230V/50Hz), US (120V/60Hz), and European (230V/50Hz) power standards when used with an appropriate USB-C charger.
How do I programme a sequential protocol into the device?+
The Health Hertz guide includes step-by-step programming instructions for both devices. In brief: use the rotary encoder to navigate to the sequence programming menu, enter each frequency and its duration in order, then save and activate the sequence. The device will step through the frequencies automatically. The Health Hertz Ripple supports up to 10 steps; the Health Hertz Shimmer supports up to 25 steps.
Are the devices safe to use around children and pets?+
Both devices generate extremely low-power electromagnetic fields in the ELF/ULF range — comparable in magnitude to the Earth's natural background field. They are not medical devices. As a precaution, we recommend keeping devices at least 1 metre from infants and young children during operation. Consult the full Legal and Medical Disclaimer in the Health Hertz guide before use.
Where do the devices ship from?+
Devices ship directly from Shenzhen, China via 4PX international logistics. Tracking is provided for all orders.
How long does shipping take?+
Typical transit times: Australia 7–14 business days; United States 10–18 business days; United Kingdom 10–18 business days; Europe 10–20 business days. These are estimates and may vary depending on customs clearance.
What is included with every order?+
Every order includes the device in its acrylic case, a USB-C power cable, and a digital download link for the Health Hertz guide (PDF). The guide is delivered via email at the time of order confirmation.
How do I receive the free Health Hertz guide?+
A download link for the Health Hertz guide PDF is included in your order confirmation email. No additional steps are required. The guide is yours to keep and share.
