Sound healing is a complementary relaxation practice, not medical treatment, and nothing on Sacred Frequency is a diagnosis or a substitute for professional care. Never delay or stop medical care because of something you read or heard here. If you have or suspect a medical or psychological condition, consult a doctor.
Where we describe what a frequency is “used for”, we are describing a tradition within sound healing, not a proven physiological effect. Claims commonly made about Solfeggio frequencies — repairing DNA, healing cells, curing disease — are not supported by credible scientific evidence, and we do not make them.
The genuine safety considerations are volume and duration. Keep the volume low enough to hold a conversation over, and sessions to twenty minutes or so. Anyone with epilepsy or another seizure disorder should avoid rhythmic audio stimulation without medical advice, as should anyone with a pacemaker or an active heart condition. Stop if you get a headache, nausea or ringing in the ears.
Sustained tones at high volume can permanently damage hearing, and a pure tone can feel quieter than it is. Start low and raise the volume only if you need to. These tools are intended for adults; any use by a child should be supervised, brief and quiet. Do not use them while driving or operating machinery. If you are in crisis, contact your local emergency number or a crisis line now.
