Integrated Learning System (Safe and Sound)
Did you know that the vagus nerve affects the nervous system and every organ in the body?
Safe & Sound Protocol uses sound frequencies to gently and effectively stimulate the vagus nerve, guiding the nervous system to relax and to calmly process sensory stimulation.
Based on Stephen’s Porges’ polyvagal theory, Safe & Sound protocol delivers high frequencies to the middle ear muscle designed to stimulate the vagus nerve. With trauma and stress, the brain develops more lower frequency neural pathways so it can recognize danger and protect us. Safe & Sound helps the brain to develop higher frequency pathways that are associated with safety. Slow, gentle, and effective, clients often complete 30 minutes of listening over 30 days to train the brain and stabilize results. The most commonly reported benefits are decreased anxiety and reactivity, and improved sleep. Partners and families are encouraged to train together to connect and harmonize in healthier ways.
About the Safe and Sound Protocol (SSP):
● The Safe and Sound Protocol (SSP) is an evidence-based listening therapy designed to reduce sound sensitivities and improve auditory processing, behavioral state regulation, and social engagement behaviors through filtered music. As a practical application of Polyvagal Theory, the SSP acts as a non-invasive, acoustic vagal nerve stimulator, helping to re-tune the nervous system to better support connection, collaboration and resilience. The SSP involves listening to specially filtered music through headphones alongside a provider, in-person or remotely. Suitable for children and adults, the SSP has demonstrated benefits for individuals with trauma, anxiety, sensory processing differences and more.
Highlights of the SSP:
● A five-hour auditory intervention developed and patented by Dr. Stephen Porges, author of the Polyvagal Theory.
● Designed to reduce sound sensitivity, and improve auditory processing and behavioral state regulation.
● Activates the client’s social engagement system, helping to accelerate and enhance therapeutic outcomes.
● Supports physiological state regulation, allowing for greater resilience.
Polyvagal Theory: The Science of Feeling Safe
Developed by world-renowned researcher and Unyte’s Chief Scientific Advisor, Dr. Stephen Porges, Polyvagal Theory focuses on what is happening in the body and the nervous system, and explains how our sense of safety, danger or life-threat can impact our behavior.
Understanding Polyvagal Theory gives us a scientific framework that can be applied through physiological, or “bottom-up” therapies, to help change and improve how we feel, think and connect with others.
