What happens between sessions: why change also occurs outside the therapy room

Do a quick calculation with me. A week has 168 hours. A therapy session lasts one. Which means you spend less than one percent of your week in the therapy room — and the other 167 hours out there: at work, in the kitchen, in bed, in conversations, in the silence of your own head. So where do you think change actually happens?

This isn’t a rhetorical trap — and it isn’t an argument against therapy either, quite the opposite. The answer is serious and backed by research: the session is the engine, but the distance is covered in between. The hour with your therapist opens something up, names it, shifts it — and those 167 hours outside are where the new understanding meets real life and either takes hold or evaporates. In this piece I’ll show you what goes on (and what can go on) between sessions, what the research on “therapy homework” says about it, and why you deserve some empty space after a session rather than a meeting fifteen minutes later.

The hour that keeps working long after it ends

You may have noticed this already if you’re in therapy: the most important moments of the week often aren’t in the session. They’re on Tuesday evening, when in the middle of an argument you suddenly see what you’re doing — for the first time from the outside, as if someone had switched on a light. They’re on Thursday, when your partner’s remark stings and, instead of your usual withdrawal, you ask yourself: “Hang on, we talked about this. What’s really going on with me right now?” They’re on Saturday morning, when over coffee two memories that had nothing to do with each other suddenly fit together.

This isn’t coincidence, it’s a mechanism. In the session you get a new reading of your experience — a new frame to look through. During the week that frame meets raw material: real situations, real people, real emotions. Only there does it get tested, and only there does it start to become part of you. The brain doesn’t change from insight alone, but from repeated experience — a new connection consolidates only when you use it. Therapy is quite literally counting on your week: without it, it’s like learning to swim on dry land. I’ve written more about how repetition reshapes neural pathways in the piece on neuroplasticity and therapy.

Homework: a word that sounds like school, but carries numbers

In many therapeutic approaches, the work between sessions isn’t left to chance — it has a name that sounds faintly like school: therapy homework. It can be observational (this week just notice when your inner critic shows up), behavioural (say no once and see what happens), written (a journal of situations and responses) or experiential (a breathing exercise when you notice tension).

And this is where the research comes in. Nikolaos Kazantzis and colleagues tested two things across a series of meta-analyses (2000, 2010, 2016): whether therapies that include work between sessions achieve better outcomes — and whether outcomes are better for people who actually do the tasks. The answer is yes on both counts: including between-session work is associated with noticeably better therapy outcomes, and the degree to which someone genuinely engages with the tasks (what’s called homework compliance) consistently correlates with greater progress. Causality is of course tangled — motivated people do more and progress faster — but the picture from dozens of studies is clear: therapy that lives only in the room is working at half power.

One thing matters, though: good “homework” isn’t an order and isn’t a test you can fail. It’s a micro-experiment designed together. If you didn’t do it, that too is valuable information — a conversation about what got in the way is often more fruitful than the task itself. (Resistance isn’t sabotage, it’s a message — I’ve written about this in the piece on resistance in therapy.)

Five forms therapy takes during the week

So what actually happens — or can happen — between sessions? In my work with people, and in myself, I notice five recurring forms:

• Noticing patterns. The most powerful first step: you change nothing yet, you simply notice. “Ah, I said yes again, even though I meant no.” Noticing alone already creates distance between you and the pattern — and distance is the space in which choice becomes possible.
• Micro-experiments. Small, safe departures from the usual: one honest sentence, one boundary set, one evening without apologising. Change doesn’t happen through grand resolutions, but through small acts you repeat — exactly the logic I described in the piece on self-confidence through action: evidence before the feeling.
• Writing. A journal, a note on your phone, three lines in the evening. Writing slows thoughts down and makes them visible; James Pennebaker’s research on expressive writing shows that simply putting emotional experiences into words benefits wellbeing and even physical health. Notes also rescue valuable material for sessions — emotions have short memories: what feels unforgettably important on Wednesday has often faded by Monday into “it wasn’t really anything”. Three written lines keep that material fresh.
• Conversations that weren’t happening before. One of the loveliest side effects of therapy: you start talking differently outside it too. You ask your partner something you never have. You tell a friend how you really are. The therapy room is the practice ground — the pitch is your life.
• The internalised voice. Over time something quiet and decisive happens: your therapist’s way of asking questions moves inside you. In the middle of a hard moment you hear “what are you feeling now — and what would you really need?” — and it’s no longer you quoting your therapist; it has become your own inner voice. Psychotherapy calls this internalisation, and it’s one of the key mechanisms of lasting change: therapy has succeeded when you no longer need the therapist, because you’re doing their job yourself.

What one concrete week looks like

So it doesn’t stay at the level of principle, let’s sketch an example. Say that in Monday’s session you and your therapist recognised a pattern: when you feel overlooked, you don’t speak up but withdraw and go cold — and your partner reads your silence as punishment and responds with distance, which deepens your sense of being overlooked even further.

On Tuesday exactly that happens. Your partner looks at their phone over dinner and the familiar chill rises in you. But for the first time in your life, something else happens alongside it: you notice it rising. You don’t do anything differently yet — you simply register: “Ah, this is it. This is what we were looking at yesterday.” That is between-session work in its purest form, and it’s worth more than it seems.

On Thursday the situation repeats and this time you try a micro-experiment: instead of withdrawing, you say one sentence out loud. “When you look at your phone, I feel invisible.” It’s awkward, your voice catches slightly, and your partner — surprise — doesn’t reject you but puts the phone down. That evening you write three lines in your notes: what happened, what you felt, what surprised you.

On Friday the pattern returns and this time the old way wins: withdrawal, chill, silence until midnight. That goes into the notes as well — without self-criticism, as data. To the next session you bring both: Thursday’s successful sentence and Friday’s slip. And it’s precisely the comparison of the two — what was different on Thursday, what was missing on Friday — that becomes the most fruitful material of the hour. That’s how the circle closes: the session feeds the week, the week feeds the session.

Why once a week — and not “as needed”

You may now also better understand why therapy usually runs to a regular weekly rhythm, rather than “whenever things get bad”. A week is just the right unit: long enough for new understanding to meet real situations, and short enough that the thread doesn’t break and the material doesn’t go cold. A regular appointment also does something quiet but important: it creates a dependable point in the week around which the process can organise itself — you know there’ll be space on Monday, so during the week it’s easier to hold and observe rather than swallowing everything or exploding.

Sessions “as needed” follow the opposite logic: you come to the therapist when there’s a fire, and the work exhausts itself in putting it out. For crises that’s entirely legitimate — but a process of change also needs the quiet weeks, because that’s exactly where the new gets built. I’ve written more about how long the process takes and when the rhythm can thin out in the piece on how long therapy lasts.

Why not to schedule a meeting after a session

And now something very practical, which I tell everyone at the start of our work: if you possibly can, don’t plan anything demanding after a session. No work meeting half an hour later, no shopping, no rushed school pick-up.

The reason isn’t a polite platitude. Sessions often open material that is emotionally alive — and emotions don’t switch off when the hour ends. The body needs time for the arousal to settle; thoughts need space to come to rest. If you fill that space immediately with demands, you cut the experience off halfway — roughly the way you’d cut someone’s sleep short in the middle of memory consolidation. A great deal of what’s most valuable actually happens in the hour after a session: on the walk to the car, on a bench, on a slow drive home. That’s where things come together.

So: a walk instead of a meeting. Ten minutes in the car before you start the engine. A coffee with just yourself. This isn’t indulgence — it’s part of the therapy, and the free part at that.

Some people turn this into a small ritual that anchors the session in the week: always the same walk home, always the same bench, always three lines in the notebook before returning to other people. A ritual isn’t an obligation — it’s simply a way of telling your body: what just happened matters and has its own place. The same goes for the hour before a session, if you can protect it: five minutes of quiet outside the door brings a more collected person into the room than a dash from a meeting with a phone ringing in your pocket.

When “nothing happens” during the week

And what about the weeks with no insight, no courage, no journal — just getting through? That’s normal too, and that’s information too. Change isn’t a straight line; it has plateaus, reverse gears and weeks when nothing seems to move while the material settles beneath the surface. Sometimes the most important “work between sessions” is simply that you got through the distress differently than before — a fraction less self-critically, a fraction more curiously.

Just watch out for one trap: don’t let the work between sessions become a new project you can fail at. If you’re a perfectionist, you may try to do therapy with distinction too — keep a flawless journal, carry out every experiment, arrive at the session with a report. But therapy isn’t a subject where you collect marks; a week without “results” isn’t a wasted week, and your therapist isn’t expecting diligence but honesty. Paradoxically, sometimes the deepest work between sessions is precisely the practice of not loading something onto yourself.

That’s exactly why it’s worth knowing the quiet signs of progress that are easy to miss — I’ve gathered them in the piece on signs that therapy is working. And if you have the sense that genuinely nothing has moved for weeks, bring that to a session. A conversation about being stuck is often the session that gets the process going again.

Your 167 hours

To sum up: therapy isn’t an hour a week. It’s an hour that changes the way you live the other 167. The session opens and names; the week tests and installs. The research on between-session work is unambiguous here — those who carry therapy with them out of the room take the most from it.

You don’t need to do everything at once. One pattern you simply observe this week. One micro-experiment. Three lines in the evening. Ten minutes for yourself after a session. That’s enough — change is the sum of small repetitions, not of grand turning points. And when you look back months later, you’ll see that it wasn’t the hour with the therapist that changed; all 168 of your hours changed — a little at a time, barely noticeably, but in the same direction.

And if you aren’t in therapy yet and reading this stirs the sense that your 167 hours could use a different kind of hour each week: on the Services page you’ll find the forms of work I offer, and the piece on the first session tells you, with no mysteries, what the beginning looks like.
