How to Stop Feeling Overwhelmed at Work

Feeling overwhelmed at work is not a sign that you have taken on too much. It is often a sign that your brain has lost the ability to distinguish between what matters now and what can wait — and without that distinction, everything feels equally urgent, equally undone, and equally impossible to start.

This is what the research says about why the overwhelmed feeling happens, and what reliably reduces it.

What Overwhelm Actually Is

Overwhelm is a cognitive-emotional state in which the perceived demands on your attention exceed your sense of capacity to meet them. The key word is "perceived." The problem is rarely the actual volume of work — it is the brain's inability to process that volume in a way that creates traction.

When demands accumulate beyond what working memory can hold, the prefrontal cortex — responsible for planning, prioritising, and executive function — begins to degrade in performance. Research by Ethan Kross at the University of Michigan and others on cognitive load shows that the sense of overwhelm is itself cognitively expensive: rumination about everything that needs doing competes directly with the capacity to do any of it.

This is why overwhelm often produces a specific, maddening paradox: you feel so behind that you cannot start, and because you cannot start, you fall further behind.

Why "Just Prioritise" Doesn't Work

The standard advice when overwhelmed is to prioritise. Write a list, identify the three most important things, and start there.

This advice is correct but incomplete, and it often fails in practice for a specific reason: prioritisation requires the cognitive resources that overwhelm has already depleted.

To prioritise effectively, you need working memory to hold multiple options simultaneously, executive function to compare them against each other, and emotional regulation to manage the anxiety that comes from feeling behind. All three are compromised when you are overwhelmed. Telling yourself to "just prioritise" when you are overwhelmed is a bit like telling someone who is hypoxic to think more clearly.

What actually helps is a different sequence: first reduce the cognitive load, then prioritise. Get everything out of your head before asking your brain to rank it. The externalisation has to come first.

The Three Causes of Workplace Overwhelm

Understanding what is driving the overwhelm matters, because the interventions differ.

Cause 1: Volume overload. The actual demands on your time exceed what is possible in the hours available. This requires negotiation, delegation, or explicitly dropping things — not a productivity technique.

Cause 2: Ambiguity overload. You have a manageable number of tasks, but the lack of clarity about what any of them requires keeps the brain in a high-activation, unresolved state. The inbox is full of unclear requests. The project has no defined next step. Ambiguity is interpreted by the threat-detection system as danger, which produces the physiological state of overwhelm even when the actual workload is reasonable.

Cause 3: Context switching overload. Constant interruptions, multi-project demands, and the need to hold multiple incomplete tasks in mind simultaneously fragments cognitive resources. Research by Gloria Mark at UC Irvine found that it takes an average of 23 minutes to return to a task after interruption. With multiple daily interruptions, many workers never complete a sustained period of focused work at all.

Identifying which cause is driving your overwhelm changes what you do about it.

What Actually Reduces Overwhelm

1. Empty the head first

Before doing anything else, spend five to ten minutes writing down every task, worry, half-formed obligation, and background concern that is running in your head. Not to organise it — to get it out.

This works because it removes the cognitive cost of remembering. Working memory has a limited capacity (typically 4 ± 1 items, according to research by Nelson Cowan). When it is full of "don't forget to..." items, less capacity is available for the actual thinking required to do any of them. The act of writing something down allows the brain to release it from active maintenance.

2. Close open loops, not just tasks

Open loops are incomplete commitments: things you said you would do, decisions you are waiting on, emails that need a response you haven't decided yet. They are particularly draining because the brain continues processing them in the background even when you are not consciously thinking about them.

Research on the Zeigarnik effect — the finding that incomplete tasks intrude on thinking more than completed ones — explains why open loops feel so costly. Each one requires cognitive maintenance. Closing a loop (by doing it, delegating it, or explicitly deciding not to do it) removes that maintenance cost.

The practical implication: when you are overwhelmed, closing three open loops often produces more relief than completing one large task, because you are removing background cognitive load rather than adding to your output.

3. Reduce task ambiguity before you start

If a task feels overwhelming because you don't know where to start, that is an ambiguity problem. The intervention is not to push through — it is to define the first physical action with enough specificity that it is no longer ambiguous.

"Work on the presentation" stays open. "Open the slide deck and write the title of slide 3" closes. The specificity is not pedantic — it is the difference between a task that activates avoidance and one that activates action.

The Priority Pad is designed around this principle: it structures the daily planning process so that you leave each task with a defined next action, not just a category of work.

4. Protect one anchor block per day

Research consistently shows that single-task focus produces better output and lower cognitive fatigue than multitasking. But most people cannot create large protected blocks of time in a reactive work environment. One hour — or even 45 minutes — is enough.

Decide in advance what that hour is for. Put it in the calendar as a block. Treat interruptions during that block as you would a meeting. The research on deliberate practice and deep work (Ericsson, Newport) both converge on the finding that cognitively demanding work requires protected, uninterrupted time — and that most people get almost none of it by default.

A Morning Routine That Reduces Overwhelm

One of the most reliable findings in performance research is that how you begin the day has a disproportionate effect on how the rest of it unfolds. This is partly neurological — cortisol is naturally highest in the first hour of waking (the cortisol awakening response), and how you direct your attention in that window influences stress responsiveness throughout the day.

A structured morning routine that includes a brief planning review — 10 to 15 minutes, not two hours — does three things that directly reduce overwhelm:

• It converts the list of everything into the list of what matters today
• It defines the first action for each priority, removing ambiguity at the moment of highest cognitive capacity
• It creates a sense of agency and control before the day's demands begin

The Morning Mindset Journal is built around this evidence base: a short, structured ritual that replaces the "where do I even start?" feeling with a clear, bounded plan before the inbox opens.

When Overwhelm Is More Than a Workload Problem

It is worth separating two different situations. The first is overwhelm driven by genuinely excessive demand — workloads that are objectively unmanageable. In that case, the right intervention is structural: negotiating scope, pushing back on requests, or having a conversation with a manager about capacity. Productivity techniques will not solve a systemic resourcing problem.

The second is overwhelm driven by cognitive-emotional patterns — perfectionism that prevents completion, anxiety that amplifies every demand, ADHD that makes prioritisation structurally difficult, or burnout that has depleted the capacity for executive function. These require different support, and sometimes professional help.

If the overwhelmed feeling is persistent, not tied to specific workload spikes, and not improving when demands reduce, it is worth speaking to a GP.

Frequently Asked Questions

Why do I feel overwhelmed even when I don't have that much to do?

Overwhelm is driven by perceived demand and ambiguity, not actual volume. A small number of tasks that are unclear, unresolved, or emotionally loaded can produce more overwhelm than a large number of clear, defined ones. If tasks feel nebulous, the first step is to define the next physical action for each one — not to do them, just to clarify what "doing them" would mean.

Does making a to-do list help with overwhelm?

Sometimes. A brain dump — getting everything out of your head onto paper — reliably reduces the sense of overwhelm by offloading working memory. But a long, undifferentiated to-do list can itself become overwhelming if it isn't filtered. The most useful form is a short daily list of the three most important tasks, derived from a longer capture list. The capture step relieves pressure; the filtering step creates traction.

Can overwhelm cause physical symptoms?

Yes. The overwhelmed state activates the same physiological stress response as physical threat: elevated cortisol and adrenaline, increased heart rate, muscle tension, and disrupted sleep. Chronic overwhelm — the kind that persists without recovery — is associated with increased risk of burnout, anxiety, and cardiovascular stress. The body responds to cognitive load in ways that are very similar to its response to external threat.

How is overwhelm different from burnout?

Overwhelm is a state — often acute, often situation-specific, and recoverable when the load reduces or a clear next step emerges. Burnout is a chronic condition that develops when overwhelm and high demand persist without adequate recovery over a long period. Overwhelm can be a precursor to burnout, but not all overwhelm becomes burnout. The distinction matters because the interventions differ: overwhelm responds to clarity and load reduction, burnout requires rest, recovery, and often structural changes to the working environment.
