Cognitive Support, Beneficial for Everyone

Support Through Relaxation, Music, and the Senses

Recovering from a traumatic brain injury (TBI) can be a long and challenging process. One of the most important aspects of healing is finding ways to calm the mind, reduce stress, and re-engage cognitive pathways that may feel disrupted. Relaxing videos, soothing music, and sensory-based activities have been shown to provide meaningful support for individuals with TBI—and the truth is, these practices benefit everyone, not just those recovering from injury.

Our brains thrive on rhythm, imagery, and sensory experiences. For someone with TBI, the brain may need extra help reconnecting and finding balance. Gentle, structured sensory input can encourage relaxation while also stimulating pathways linked to memory, focus, and emotional regulation. For example, watching a peaceful video of waves rolling onto the shore or birds flying through a forest gives the brain a chance to process calm, predictable patterns. This predictability reduces overstimulation and allows the nervous system to settle, which can lead to better concentration and a sense of safety.

Music also plays a powerful role. Slow, melodic tunes have been shown to lower blood pressure, ease anxiety, and encourage deeper breathing. For TBI patients, music can act as a bridge between emotions and memory. Even simple rhythms or familiar songs can spark recognition, improve mood, and support cognitive recovery by gently activating areas of the brain tied to speech and recall. For anyone, music becomes a natural form of stress relief, providing a way to reset mentally and emotionally.

The senses go beyond what we hear and see. Touch, smell, and even taste can help re-establish cognitive stability. A soft blanket, the scent of lavender, or sipping warm tea are examples of grounding sensory experiences. These small comforts activate the parasympathetic nervous system—the body’s natural relaxation response—which can lower cortisol levels and promote healing. For TBI patients, carefully chosen sensory input helps reduce frustration and fatigue while gently training the brain to process experiences in a calmer way.

Relaxing videos, calming sounds, and sensory activities can also help with sleep, which is often disrupted after a brain injury. Good sleep is vital for cognitive recovery, memory consolidation, and emotional well-being. Establishing routines that include sensory relaxation—such as watching a calming video before bed or listening to soft music—can prepare the brain and body for restful sleep.

Importantly, these methods are not limited to those healing from TBI. In today’s fast-paced world, stress, overstimulation, and burnout affect nearly everyone. Incorporating sensory relaxation practices offers a natural way to support mental clarity, reduce anxiety, and improve overall cognitive health. Whether you are healing from an injury, working long hours, or simply needing a moment of calm, engaging your senses through relaxation is a powerful tool.



In summary, the use of soothing videos, calming music, and sensory experiences creates a pathway to cognitive support and recovery. For TBI patients, these practices are especially valuable, but they remain universally beneficial. By nurturing our senses, we nurture the brain—and when the brain is cared for, the whole person can thrive.

What Frequencies Actually Do In The Brain

Neural entrainment happens when a rhythmic stimulus (sound or light) nudges large groups of neurons to oscillate together. In hearing, this is best captured by the auditory steady-state response (ASSR)—especially around ~40 Hz (gamma)—which links to attention, processing speed, and GABAergic (inhibitory) circuitry. That’s a mechanistic foothold for cognition and rehabilitation, including after TBI. PMCMDPIJournal of Neuroscience

• Crucially, entrainment is driven by the modulation (beat) rate, not the high-pitched “carrier” tone. A 528 Hz pure tone doesn’t make your cortex oscillate at 528 Hz; if you amplitude-modulate it at, say, 6 Hz, the brain may track ~6 Hz (theta), which relates to relaxation and memory encoding. This is why studies of binaural/beat stimulation focus on delta/theta/alpha/gamma beat rates (e.g., 4–12–40 Hz), not the carrier pitch. Evidence for mood/sleep effects exists, but results are mixed.

Where TBI Rehab Has The Strongest Footing

• In TBI, the best-supported audio approach is music-based neurological rehab using rhythmic auditory stimulation (RAS) to improve gait, timing, and attention—leveraging rhythm, not a specific pitch. Meta-analytic and pilot data show medium improvements in gait measures after TBI with music/RAS. PMCScienceDirectPubMed

528 Hz, 963 Hz, 432 Hz — What We Actually Know

• 528 Hz (“Solfeggio”): A small human study (n=9) reported lower salivary cortisol and higher oxytocin after 5 min of music “at 528 Hz” versus 440 Hz. Caveats: very small sample, short exposure, and the journal is low-tier; results need replication under tighter controls (blinding, matched stimuli, preregistration). Animal/cell studies exist but aren’t directly generalizable to people with TBI. SCIRPSCIRPPubMed
• 432 Hz (vs 440 Hz tuning): Several human studies (including one on healthcare workers) suggest slightly lower anxiety and heart rate with 432 Hz-tuned music compared to 440 Hz, over short sessions. Effects are modest and mechanism likely relates to listener preference/pleasantness, not frequency-specific neurobiology. PMCPubMedScienceDirect
• 963 Hz: Popular in wellness circles, but no credible peer-reviewed human data specific to cognition or TBI. Claims are largely anecdotal or marketing-based. Immersive Sound Experience

How We Make This Useful For Victoria (evidence-aligned)

1. Prioritize rhythm and preference
   Use steady, comfortable tempos (e.g., 60–80 BPM for relaxation; individualized tempos for gait training). Patient-preferred music improves engagement and autonomic calming—both matter for neuroplasticity. PMC
2. If using “828-606-4904” tones, modulate them
   Layer gentle amplitude modulation or binaural beats at theta (4–8 Hz) or alpha (8–12 Hz) for relaxation/attention, or ~40 Hz for alertness—keeping volume low. This targets entrainment mechanisms that have neurophysiology behind them. PMC+1
3. Dose & safety
   Short, repeatable blocks (10–20 min), <70 dB listening level, eyes closed, diaphragmatic breathing. Track changes in tension, HR, and perceived exertion. (Many TBI patients have sound sensitivity.)
4. Pair with function
   Combine audio with task-specific rehab (gait steps, dual-task attention drills, speech pacing). That’s where carryover happens. PMC

Bottom Line

• For TBI recovery, the strongest science backs rhythm-based music therapy and entrainment at behaviorally relevant beat rates (theta/alpha/gamma), not specific carrier pitches like 828-606-4904 Hz.
• 432 Hz may feel a bit calmer for some listeners; 528 Hz has one small, low-rigor human study suggesting stress-hormone shifts; 963 Hz lacks evidence. If these tones are soothing and tolerated, you can absolutely use them as the carrier, but focus the modulation/beat frequency and the rehab task to tap mechanisms that help cognition and function.
