Your brain isn't a light switch.
It's a training curve.
Tihna is not a drug and does not work like one. It's a structured 4-week programme that guides your brain into specific rhythmic states, and — over time — makes those states easier for your brain to reach on its own. Here's exactly what happens, week by week.
The core idea in one paragraph
Your brain produces electrical rhythms — delta, theta, alpha, beta, gamma — each associated with a different mental state. Sleep runs on delta and theta. Calm sits in alpha. Focus lives in beta and gamma. When your brain is stuck in the wrong rhythm at the wrong time (beta at 2 a.m., theta at 10 a.m.), the state you want feels out of reach. Neural frequency programmes work by presenting your brain with a pattern it wants to synchronise to — a technique the research literature calls brainwave entrainment. Over minutes, your brain follows the pattern. Over weeks, it gets better at producing that rhythm on its own.
Two effect layers you need to understand before you start
Every peer-reviewed study on neural frequency training measures two separate effects at two separate timescales. Confusing them is the single most common reason people say "it didn't work."
Layer 1: The acute effect
Measurable brainwave changes within minutes of a session starting. Feeling calmer during the audio, falling asleep faster while it plays, feeling more locked-in immediately after. This is the brain warming up — it's real but transient.
Layer 2: The trait effect
Cumulative changes that show up after 2–4 weeks of consistent use. A calmer baseline. Easier-to-reach focus. Better sleep even on nights you don't listen. This is what you actually want — and this is what needs the training curve.
The trap: Expecting layer 2 outcomes from layer 1 exposure. If you listen once, don't feel a dramatic shift, and quit, you never let the training effect accumulate. The research is unambiguous on this — single sessions don't produce durable change.
The 4-week arc, week by week
Every Tihna programme (Sleep, Calm, Focus, Morning) is structured as a 4-week arc because that's what the peer-reviewed evidence indicates you need for durable, trait-level changes to appear. Here's the honest week-by-week picture:
You'll feel during-session effects. Calmer while the audio plays. Falling asleep faster on nights you use it. More focused immediately after a focus session. What you probably won't feel yet is any change to your default state when you're not listening. That's normal. Don't quit here — this is where most people who dismiss binaural beats give up.
If you're on the Sleep protocol, this is typically when the compound effects begin showing up — waking less during the night, sleeping longer, waking more restored. A 2022 pilot study of delta binaural beats found statistically significant improvements between week 1 and week 2 across all three sleep metrics (p < 0.001). Focus and calm protocols are still mostly in acute-effect territory here; keep going.
This is where Focus and Calm protocols start producing changes you can measure — not just feel. Sustained attention feels slightly easier and lasts longer. Baseline anxiety on a 1-10 scale is a point or two lower than it was in week one. The changes are subtle enough that a lot of people don't notice them until they think back explicitly to compare.
A 2020 study using 40 Hz gamma binaural beats across 8 sessions over 4 weeks found statistically significant improvements in memory (p = 0.0027) measured at the end of the programme. The sleep literature typically shows benefits plateauing at 4–6 weeks. This is the point at which most people go from "I guess it's helping a bit" to "I don't want to be without this."
What to expect from each programme
Different programmes work on different timescales. Here's what the research suggests you'll notice, and when:
| Programme | Week 1 | Week 2–3 | Week 4+ |
|---|---|---|---|
| Sleep | Falling asleep faster during use | Fewer awakenings, longer sleep duration | Restored default sleep quality |
| Calm | Calm during and just after session | Faster return to calm after stress | Lower baseline anxiety across the day |
| Focus | Sharper focus during the session | Longer sustained-attention blocks | Easier to enter focus without audio |
| Morning | Faster wake-up alertness | Cleaner mental state 30 min after waking | More consistent morning energy |
The five things that make the difference
Wear headphones
Binaural beats require two slightly different tones reaching each ear separately. Speakers, soundbars, and bone-conduction headphones don't work — the two tones mix, and no beat frequency is generated.
Show up daily
Consistency beats duration. Fifteen minutes daily beats a 90-minute session once a week. The training curve is driven by repetition, not total exposure.
Match frequency to goal
Delta and theta for sleep. Alpha for calm. Beta and gamma for focus. Using a calm protocol to try to focus will feel like the app "doesn't work" — because it's not designed for that.
Reduce noise around you
Trying to entrain in a loud, over-stimulating environment is like trying to strength-train while asleep. The stimulus is there, but the neural conditions for adaptation aren't.
Give it four weeks
Not four days. Not one week. Four. Every credible peer-reviewed protocol runs for at least a month, because that's what the underlying neuroscience demands.
Measure your baseline
Write down two or three baseline numbers on day one — sleep latency, focus block length, anxiety score. Check them at day 30. Numbers don't lie; feelings across weeks are hard to remember.
Why programmes are 4 weeks — not longer, not shorter
Tihna's programmes are structured as 4-week protocols because that's the sweet spot the peer-reviewed evidence points to. Shorter than that, and trait-level changes haven't had time to accumulate. Longer than that, and the marginal gains from each additional week start diminishing.
The Focus protocol, for example, uses a 15 Hz beta primer in weeks 1–2 to build attentional stability, before shifting to pure 40 Hz gamma in weeks 3–4 for the cognitive-consolidation phase — matching the training pattern that produced statistically significant memory improvements in Sharpe et al. (2020). The Sleep protocol progresses from theta primer to deep delta over the same arc, matching how sleep-onset training compounds in the delta-binaural literature.
What Tihna will not do
Being honest about what neural frequency programmes don't do matters as much as being clear about what they do:
- Tihna is not a medical treatment and does not diagnose, treat, cure, or prevent any condition
- Tihna will not make you feel dramatically different in the first session — if you're expecting a caffeine-like hit, you'll be disappointed
- Tihna is not a substitute for professional care for insomnia, anxiety disorders, ADHD, or any other clinical condition
- Tihna will not work if you skip weeks, listen without headphones, or use a programme designed for the opposite goal
- Tihna will not benefit everyone equally — a minority of people don't respond strongly to binaural stimulation, a well-documented individual variability in the literature
Do not use Tihna if you have epilepsy, a pacemaker, or are pregnant. If you have any medical condition, consult your doctor before using Tihna.
