Quick answer

What should you do before a focus session?

Choose one visible finish line, remove the interruption you can predict, and write the next action before you begin. If you use audio, keep it comfortable and treat it as part of the routine—not proof that a particular sound will make you perform better.

The six-step setup

  • Write one task and one finish condition.
  • Prepare the files, tools and first action.
  • Silence non-essential alerts for the session.
  • Write a short restart cue in case you are interrupted.
  • Set a comfortable headphone volume.
  • When the session ends, record the next step before switching tasks.

The familiar problem is not a lack of ambition. You sit down to do one task, notice a message, answer a “quick” question and return without remembering the exact decision you were making. Research consistently treats that return as work: interruptions create a resumption lag and can affect accuracy, although the size of the effect depends on the task and the interruption.

1. Turn “focus” into one finish line

“Work on the proposal” is too broad. Choose an outcome that can fit inside one session: draft the opening section, reconcile ten transactions, review one pull request, or outline three slides. Write the finish condition where you can see it.

This is not a promise that a checklist eliminates distraction. It removes one decision from the session: what you are trying to finish.

2. Prepare the first action

Open the file, gather the source material and close the tabs that are unrelated to the task. Then write the smallest first action—for example, “compare the two totals” or “write the first three headings”. Starting with a concrete action is easier than asking yourself to become focused on command.

3. Remove predictable interruptions

A 2021 systematic review and meta-analysis examined 33 laboratory experiments covering 49 interruption interventions. Across those controlled studies, interventions improved primary-task accuracy and reduced resumption lag overall, but effects varied by intervention and task type. The laboratory setting limits how directly the result transfers to a normal workday.

Use that evidence modestly: silence non-essential notifications, tell people when you will be available, and keep urgent channels available where your role requires them. Do not use a focus routine to ignore safety, care or operational responsibilities.

4. Leave yourself a restart cue

Before you answer an unavoidable interruption, write one line: “I was checking X; next I need to do Y.” Research on interruption recovery suggests that cues can help people resume, but results depend on the cue and task. A recent controlled multitasking study found assistant-style cues improved some post-interruption performance while simple retrieval cues did not consistently do so. That is a reason to make your note specific, not evidence that one universal cue works for everyone.

5. If you use audio, choose comfort before claims

Tihna's Focus programme uses finite 25-minute stereo-headphone sessions. You can choose from eleven nature soundscapes or Pure Tone, complete the session and review progress afterwards. That product structure can act as a clear beginning and end for your routine.

The science does not justify promising that a binaural beat will make you concentrate. A 2023 meta-analysis reported an overall effect across 15 studies of memory and attention, but its systematic review found conflicting results across frequencies and tasks. A separate 2023 review of EEG entrainment studies found contradictory outcomes, small young-adult samples and substantial methodological variation. Neither review tested the complete Tihna app.

Keep the volume comfortable. The World Health Organization recommends keeping personal listening devices at no more than about 60% of maximum and, where sound-level monitoring is available, below an average of 80 dB. Lower the volume further if it feels loud, and seek professional advice for persistent ringing or hearing difficulty.

6. Close the session before you switch

At the end, write what you completed and the next action. If the task is not finished, that line becomes tomorrow's start point. The aim is a repeatable return path, not a perfect uninterrupted day.

Copy the checklist

  • Task: What one result will exist when this session ends?
  • First action: What will I do in the first two minutes?
  • Environment: Which alert, tab or device can I remove?
  • Interruption rule: What must stay available, and what can wait?
  • Restart cue: If interrupted, what exact next action will I write down?
  • Audio: Is the volume comfortable and the headphone setup appropriate?
  • Close: What did I finish, and what is the next step?
