What Is Stress?
Stress refers to two things at once: the psychological perception of pressure, and the body's response to it — a response that involves multiple systems, from metabolism to muscles to memory. This reaction is not just widespread, affecting almost all systems of the body and brain, but automatic, triggered by any perceived threat or demand that exceeds a person's ability to cope.
The automatic response system set off by the perception of threat is activated through hormonal signals, designed to instantly prepare you to meet a threat head-on or flee from it — the fight-or-flight response. Some stress is necessary for all living systems; it is the means by which they encounter and respond to the challenges and uncertainties of existence. Short-term, moderate doses of stress increase alertness, boost immunity, and spur brain growth.
A large proportion of workers worldwide experience high levels of stress on a daily basis — and the primary cause is poor management practices, not workload itself. Reframing how a situation is appraised can meaningfully reduce its impact.
Short bursts of stress aren't inherently harmful, although it can take time for the body to calm down. The goal isn't to eliminate stress entirely — that's neither possible nor desirable — but to keep it within a range where it sharpens rather than overwhelms you.
The 3 Types of Stress
Distinguishing between these three types helps you see your own circumstances more clearly, and points toward the right response.
Acute stress
A single, short-term event — being behind on a deadline, a near-miss car accident, an urgent call. Heart races, blood pressure rises, a sense of emergency might trigger a headache or chest tightness. These symptoms typically subside once the stressor passes.
Episodic acute stress
Some people experience these mini-crises regularly and live in a state of ongoing tension — a poorly managed workplace, recurring tight deadlines. The symptoms are similar to acute stress but occur more often and accumulate, wearing away at relationships and work over time.
Chronic stress
Ongoing, unrelenting pressure. Many people stop fighting for change and begin to accommodate it — which feeds both chronic and acute serious illness. Getting help and not blaming yourself is essential; chronic stress is rarely something willpower alone resolves.
18 Warning Signs
It can be surprisingly hard to notice how stress is affecting you, partly because the body adapts gradually — you simply get used to it, even as it takes a toll on health and wellbeing.
Muscle tension
The body braces for action; over time this feeds back into the mind, reinforcing unease.
Poor sleep
The brain resists being unconscious "in danger" — sleep is often the first casualty.
Social withdrawal
Dealing with people can feel like "too much" — an easily-missed but key sign.
Memory & focus problems
Poor judgment, racing thoughts, and a tendency to see only the negative.

What Chronic Stress Does to the Body
Recognised warning signs of stress — yet most people don't notice they're stressed because the body adapts gradually, masking the toll until it accumulates.
Over time, prolonged stress can lead to changes in many systems of the body. It activates inflammatory pathways and promotes many disorders associated with aging. Prolonged production of the stress hormone cortisol suppresses immune cell production and creates chronic, low-grade inflammation — reducing natural killer cells and lymphocytes, increasing susceptibility to viruses and infections, and delaying recovery.
Persistent stress can also lead to compromised cardiac function and gastrointestinal issues, and is closely tied to both depression and anxiety. Chronic activation of stress hormones can contribute to severe anxiety symptoms — racing heartbeat, nausea, sweaty palms, a sense of impending doom.
Stress is not an illness in itself, but chronic stress makes a person more susceptible to serious illness — which is exactly why learning to recognise and address early symptoms matters so much.
Common Causes
Stressors can be positive or negative — getting a new job and losing one can both cause stress. Major life causes include illness or death of a loved one, marriage or divorce, financial issues, moving house, and having a baby. Acute stress is often triggered by everyday pressures: studying for an exam, preparing a presentation, or an argument with someone close to you.
At work specifically, research consistently points to management quality as the leading driver — more so than workload itself. You likely can't change your boss, but you can change how you appraise the situation: checking whether you're catastrophizing or engaging in all-or-nothing thinking, breaking large tasks into manageable parts, and focusing on one thing at a time rather than multitasking.
The Mindful CBT Approach
Since the stress response begins in the brain with the perception of danger or the unknown, the most effective way to diffuse stress is often to change how a situation is perceived — so it isn't seen as threatening in the first place.
Mindful — return to the present
Much of our stress comes from looking ahead and fearing we're not up for what's coming. Mindfulness invites you back to the present moment, which is almost always more manageable than the imagined future.
Cognitive — catch the unhelpful thought
Train your mind to recognise unhelpful and untrue thoughts, such as "it will be terrible if I don't finish this today." With practice, you can see through beliefs that add unnecessary stress.
Behavioral — choose a different action
With greater awareness and clearer thinking, choose actions that genuinely reduce stress — including saying "no" to things that would overextend you.
Reframe demanding as exciting, not dire
Research shows that seeing a challenge as demanding rather than threatening protects against the corrosive effects of stress while preserving its benefits — sharper focus and faster information processing.
"You can't completely eliminate stress from your life, but you can control how much it affects you. Changing your relationship to stress is often more powerful than changing the circumstances themselves."
When to Get Professional Help
If stress symptoms aren't easing with self-help techniques, or you're feeling persistently overwhelmed, it's time to talk to a professional.
🔴 Stress has lasted more than a few weeks without easing
🔴 You're relying on alcohol or substances to cope
🔴 Sleep, appetite, or concentration are significantly affected
🔴 You're withdrawing from people you care about
🔴 Physical symptoms (chest pain, persistent headaches) appear without medical cause
🔴 Stress is starting to feel permanent rather than situational
Chronic stress responds very well to support — whether that's a structured coaching relationship, cognitive behavioral therapy, or simply having a professional help you see your situation with more clarity.
