When Frequency Therapy Is Risky – Contraindications and Limits – Absolute Transparency

PEMF: Pacemakers and Implants

PEMF is absolutely contraindicated for the following groups:

Pacemakers and ICDs: Magnetic fields can disrupt device programming or trigger unwanted stimulations
Cochlear Implants: Electromagnetic interference possible
Pregnancy: Insufficient safety data for the first trimester
Active bleeding tendency: PEMF promotes blood circulation and tissue regeneration – counterproductive in acute bleeding
Malignant tumors in the treatment area: Exception: TTFields – but only under oncological supervision

Binaural Beats: Epilepsy and Psychosis

For audio frequency therapy:

Photosensitive Epilepsy: Absolute contraindication for light stimulation (40 Hz flicker). For pure audio application, the risk is significantly lower, but consultation with neurology is recommended
Active Psychosis / Schizophrenia: Theta frequencies can intensify dissociative processes
Acute emotional crisis: Deep relaxation may intensify withdrawal tendencies – professional guidance recommended
Auditory sensitivity: Start slowly, 50–60% normal volume max.

Low-Frequency Noise: Everyday Risks

Uncontrolled infrasound (< 20 Hz) and Low-Frequency Noise (LFN, 20–200 Hz) are real environmental problems. Symptoms of chronic LFN exposure: sleep disturbances, concentration deficits, mood swings (Vibro-Acoustic Disease). Sources: wind turbines, industrial motors, HVAC systems.

The Most Important Rule

Frequency-based approaches are complementary – never a substitute for acute emergency medicine. In case of heart attack, stroke, severe trauma, or oncological emergency: call emergency services. Frequency-based approaches have their place in wellness, relaxation, and as a complement to professional care – not in the emergency room.
