The neuroscience of taking breaks

How the brain uses pauses for learning, clarity and decision-making

What determines high performance over time?

Across roles, industries and levels of seniority, the pattern looks remarkably similar: sustained focus, constant digital input and very little space between tasks. Although performance doesn’t disappear under these conditions, it does become more expensive.

As a leader, you make hundreds of decisions daily under time pressure and emotional load. How you distribute effort - and how often you let your system reset - shapes decision quality, learning and leadership presence.

Why breaks improve performance

Long days and back-to-back meetings stretch your focus thin, and it’s tempting to assume that staying switched on longer delivers better output.

I’m here to tell you that it won’t.

Breaks are often framed as time away from work when, neurologically, they are part of the work.

When effort runs continuously without recovery, you “use up” all your cognitive resources. This can lead to narrowed attention, greater effort to regulate your emotions, longer decision-making and less efficient learning.

Research shows that well-timed breaks:

• Protect focus across multiple tasks

• Reduce cognitive fatigue before it accumulates

• Stabilise emotional tone under pressure

• Promote learning and integration

• Improve decision quality later in the day

Adam Grant makes a similar point in Chapter 4 of Hidden Potential, explaining that progress is best when practices include pauses, because stepping away protects motivation, opens new angles on a problem and ensures that learning sticks.

What’s happening in the brain

Sustained focus relies heavily on executive control (the brain’s “steering” functions), which are strongly associated with prefrontal systems. Over time, prolonged cognitive load is linked with mental fatigue and reduced efficiency in control processes.

Periods of rest and “offline” attention (including mind-wandering and wakeful rest) are associated with memory consolidation and integration. This means that your brain still processes in the “background”, especially after learning.

Different kinds of breaks (and what they support)

Pauses work best when they serve a clear function, because different types of breaks influence different aspects of performance.

1. Physical breaks

Physical breaks involve changing posture or introducing light movement to reduce physical and cognitive strain. These breaks alter sensory input to the brain and enhance circulation, which improves alertness and mental flexibility.

The best part? You don’t have to exercise or leave the building. Any movement, big or small, gives your brain a different stream of information to work with.

Examples include:

• Standing up after long periods of sitting

• Stretching large muscle groups

• Gentle mobility movements

• Short walks

1. Emotional breaks

Emotional load draws heavily on cognitive resources. Without pauses, emotional residue carries over into the next task. Emotional breaks allow the nervous system to step out of emotionally demanding or reactive states, especially in high-pressure environments.

Examples include:

• Brief pauses after difficult conversations

• Slow, regulated breathing

• Moments of stillness

• Stepping outside for a few minutes.

1. Intellectual breaks

Insight becomes accessible when the brain has space to integrate information rather than actively process it. These breaks go well with learning-heavy or strategy-heavy days, especially when you’ve been “inside the problem” for too long.

Examples include:

• Stepping away from active problem-solving

• Unstructured thinking time

• Allowing the mind to wander briefly (i.e. daydreaming for short periods of time)

1. Social media breaks

Rapid, high-variety content fragments attention and increases cognitive noise. Even brief social media breaks protect focus and make it easier to re-engage with meaningful work.

Examples include:

• Not checking social media between tasks

• Keeping your phone off or to one side during short breaks

• Limiting scrolling during the workday

1. Digital breaks

Reducing screen exposure when possible boosts endurance throughout the day. It protects afternoon performance and decision quality by allowing your brain to disengage from continuous executive demand and restore attentional capacity before the next block of focus.

Examples include:

• Eating away from your desk

• Spending time in nature without devices

• Short offline periods during the day

A case from the field

One of my clients is a marketing director in the healthcare industry, which is an environment defined by complexity, responsibility and emotional load.

She noticed that traditional one-on-one and team meetings were cognitively heavy. Although conversations were productive, they were also mentally taxing and strategic clarity often arrived after the meeting rather than during the meeting.

So internal meetings became walking meetings.

Instead of changing the agenda, my client changed the setting. Movement became part of the conversation, without turning it into “exercise” or adding extra time. As a result, conversations opened up, problems felt easier to work through, ideas surfaced without being forced and decisions felt clearer in the moment.

From a neuroscientific perspective, this makes a lot of sense. Movement shifts how the brain processes information, activating networks linked to creativity, memory and emotional regulation, which improves strategic thinking.

Over time, this rhythm became part of how my client led. Conversations became more grounded, more human and strategically “cleaner”. Why? Because her brain was recovering during the workday instead of trying to catch up after hours.

Anyone can do it

Regardless of who you are or where you work, the brain you bring to work operates on the same principles. When you treat breaks as part of your performance system, they become one of the most accessible tools available.
