Short answer. For most people, SSP is low-risk, but a small number of conditions require caution, medical clearance, or mean SSP is not appropriate at all, which is why every new participant goes through a screening before starting.
- SSP is low risk for most adults and children when it is paced gently
- A handful of conditions are contraindications: active or uncontrolled seizures are the clearest example
- Several others require caution and medical clearance first, not an outright no
- The screening gate exists to catch these situations before you begin, not to gatekeep
- SSP is not a crisis tool and does not replace medical or psychiatric care
What is the general safety record of SSP?
Dr. Stephen Porges and his research group spent roughly two decades testing the protocol that became SSP across several hundred children, across diagnoses including autism spectrum conditions, auditory hypersensitivities, and behavioural regulation difficulties. Over that period, no major adverse effects were observed. Occasionally, children showed an initial sensitivity to headphones, or mild anxiety linked to the listening context. Both resolved quickly.
That is a reassuring track record, and it is worth naming. At the same time, it does not mean SSP is without any risk for anyone. Porges's own clinical guidance is clear: the protocol is low risk for most people, and a much smaller group needs either a modified approach, prior medical consultation, or a different path entirely.
With the self-serve version available through this site, the SSP app licensed from Unyte Health, this practice recommends listening in short sessions of around 5 to 10 minutes a day. A full round unfolds slowly, usually over one to two months, paced to how you are responding. That gentler, self-paced delivery is built with safety in mind, but the screening before you start is still non-negotiable. 1
Two decades of research found no major adverse effects, but that record comes with genuine contraindications that matter for a minority of people.
Who should not do SSP, or should wait?
There is a difference between a contraindication and a precaution. A contraindication means do not proceed. A precaution means proceed only with care, after consulting the relevant medical provider.
The clearest contraindication is active or uncontrolled seizures. If you are currently experiencing seizures that are not under medical management, SSP is not appropriate. If you have a history of seizures that are now managed, that is a precaution situation: medical clearance from a neurologist is needed first, listening is slowed further, and your neurologist should advise on monitoring.
Several other situations sit in the precaution category rather than the outright no category.
Modulation disorders
Conditions like bipolar disorder, borderline personality disorder, and dissociative disorders can involve rapid swings in physiological arousal. SSP can amplify that. A psychiatrist's input is needed before starting.
Structural ear differences
Perforated eardrums, stapedectomy, tympanostomy tubes. The effect of the filtered audio on structurally altered ears is not well understood. An audiologist or ENT should weigh in first.
Severe hearing sensitivity
Conditions like hyperacusis or misophonia require careful volume management throughout. Starting with speakers rather than headphones may be advisable.
Active psychiatric crisis
If you are in an active crisis, recent psychiatric hospitalisation, or on antipsychotic medication for psychosis, SSP is not the right starting point. Stabilisation comes first.
Certain neurological and autoimmune conditions
The screening process flags conditions that require a doctor's clearance before participation. SSP has not been shown to treat inflammation or autoimmune disease, and for some of these conditions the screening tells you to get medical clearance before you start.
Active, uncontrolled seizures are the clearest contraindication; several other conditions are precautions that require medical clearance, not a permanent no.
What is the theoretical basis, and is the science settled?
SSP is built on polyvagal theory, the model developed by Dr. Stephen Porges. The theory proposes that the autonomic nervous system has three functional states and that cues of safety, including vocal prosody, are processed through a pathway Porges calls the ventral vagal system. The idea behind SSP is that specially filtered music, designed to emphasise the acoustic frequencies of human speech, may provide cues that the autonomic nervous system interprets as safety, and that this could, over time, influence how the middle-ear muscles process sound.
That proposed mechanism is genuinely contested in the scientific literature. Polyvagal theory is not a settled consensus. Serious researchers dispute some of its core premises, and the precise way SSP produces its reported effects is not fully established. It is right to name that honestly.
What is also true is that Porges's group published peer-reviewed findings describing positive outcomes across several populations, and clinical trials have been registered on ClinicalTrials.gov to study the protocol further. What people commonly report includes reduced sound sensitivity, greater ease in social situations, and a calmer baseline. Those reports are real, even if the exact mechanism that produces them is still a theory being tested rather than a fact being confirmed. 2,1,3
Polyvagal theory is the explanatory frame behind SSP, and it is a theory under active scientific debate, not settled fact, but the reported outcomes are real and the research base is growing.
Why does the screening gate exist, and what does it check?
The screening before you begin SSP is not bureaucracy. It is the mechanism by which the situations described above, the contraindications and precautions, get caught before you invest time and money in something that is not right for you yet.
The screening is 4 quick questions and takes under a minute. It checks whether you have any of a listed set of conditions that mean you should get a doctor's clearance before you proceed. It does not diagnose you, and nobody reviews your answers.
If the screening flags something that needs a doctor's view first, you will be told that plainly. If nothing is flagged, you move forward. Choosing between self-serve and Naadham is up to you.
This is a small investment with a real ask for honesty on your part. The screening works only if you fill it in accurately.
The screening gate is there to protect you, not to filter out people who are hard to work with. If it points you toward medical clearance first, that is the right answer for right now, not a rejection.
Screening exists to catch contraindications and precautions before you begin, not to gatekeep, and it only works if you are honest in filling it out.
What SSP is not designed to do
SSP is not a crisis intervention. If you are in acute distress, experiencing active suicidal ideation, or in a psychiatric emergency, please contact a mental health crisis service or go to your nearest emergency facility. SSP cannot help in that moment and is not designed to.
SSP is also not a replacement for medical or psychiatric care. If you are managing a diagnosed condition, whether neurological, psychiatric, or autoimmune, SSP sits alongside your existing care team, not instead of it. The screening asks about the conditions that need a doctor's clearance precisely so that the two do not work at cross purposes.
Finally, SSP has not been shown to reduce inflammatory markers or treat autoimmune disease. If you are arriving here hoping it might address something physical in that category, the honest answer is that this is not what SSP does, and some autoimmune and neurological conditions need a doctor's sign-off before you proceed.
SSP is not a crisis tool, not a psychiatric replacement, and has not been shown to treat inflammation or autoimmune conditions.

| Cost | Rs 7,999 for 3 months, one payment | Varies; typically higher due to provider time |
| Contraindications | Same list applies, screening catches them | Same list applies, provider catches them in session |
Not sure if SSP is right for your situation?
The screening takes under a minute and gives you a plain answer. If a condition means you should check with a doctor first, it tells you. If not, you will know how to move forward.
