A study says your brain may treat making coffee, brushing your teeth and locking the door differently once they become habits

Imagine walking into the kitchen one morning. You reach for your usual mug while thinking about the day ahead. You have not stopped to debate whether to make coffee. The routine is already underway.

Later, brushing your teeth feels familiar. At the front door, your hand moves towards the lock as you prepare to leave. Ordinary actions can become closely tied to the situations in which you repeat them. Habit researchers suggest that familiar cues can help start a routine. They can also make its steps feel easier to carry out.

What did the daily-life habit study find?

Researchers led by Amanda L. Rebar, with psychologist Benjamin Gardner among the authors, studied 105 adults in the UK and Australia. Participants reported their behaviour six times daily over seven days. They also described how habitual and intentional each action felt.

Published in Psychology & Health, the paper first appeared online in September 2025. It appears in a 2026 journal issue. Around 65% of reported behaviours were habitually started. About 76% aligned with what participants intended to do.

The categories could overlap. An action could be habitual and wanted.The study relied on self-reports. It did not use brain scans to observe coffee-making or door-locking.

How can your kitchen become a cue for coffee?

Psychologists Wendy Wood and David T. Neal explain habits through learned links between a situation and a response. Repeating an action in a similar setting helps build that association. Eventually, encountering the setting can prompt the familiar response.

A cue need not be a physical object. Finishing one action can become the signal for starting another.For example, clearing breakfast might regularly lead to brushing your teeth.

The coffee scene illustrates the same idea. Entering the kitchen may help prompt a routine you have repeated there many times. You may still want the same drink. The cue simply reduces the need to begin with a fresh discussion.

Is starting a habit different from doing it automatically?

Yes. Researchers distinguish “habitual instigation” from “habitual execution.”The first concerns what gets an action started. The second concerns how smoothly its smaller steps unfold.

Gardner and colleagues developed this distinction in earlier research. Imagine deciding to make coffee, then carrying out the familiar movements without planning each one. The beginning could be deliberate, while much of the execution feels automatic.

The reverse is possible too. A cue might get you started, but an unfamiliar coffee machine then demands attention. Automaticity can apply to part of a routine.

Can a familiar setting influence what you do despite your preferences?

A popcorn experiment offers a striking example. In research published in 2011, Neal, Wood and colleagues examined people with established cinema-popcorn habits.

At a cinema, habitual popcorn eaters consumed similar amounts of stale and fresh popcorn. Their eating was relatively unaffected by hunger or how much they liked the food. The pattern depended on the familiar setting. It did not appear in the same way outside that context.

Another experiment disrupted the usual eating movements by asking participants to use their non-dominant hand.The findings show how context and familiar execution can sustain a habit. They do not mean preferences never matter.

How does repetition make a routine feel easier?

Psychologist Phillippa Lally and colleagues at University College London followed 96 volunteers for 12 weeks.

Participants chose a behaviour to repeat daily in the same context. They recorded whether they performed it and how automatic it felt. Repeated behaviour generally became more automatic over time. The pace varied considerably.

Missing one opportunity did not materially disrupt the formation process observed in that study.

A useful lesson for everyday routines is to pay attention to the setting as well as the action. Repeating something after the same familiar event may help establish a reliable association.

Does having habits mean you stop choosing?

No. Habits can support choices you have already made. Wanting clean teeth and brushing them habitually can coexist. The same applies to a morning routine you enjoy.

The daily-life study’s intention findings matter here. Habitual behaviour was often consistent with what people wanted. Understanding a cue gives you another way to examine a routine.

Back in the kitchen, the mug remains in its usual place. Now you have a better explanation for why reaching for it feels so natural.
