Stress, worry and anxiety - what's the difference?

It’s easy to confuse stress, worry and anxiety — they often feel similar and may show up together. But they’re not quite the same thing. Understanding their differences is an important step towards managing them more effectively. Think of them as members of the same family: related, but each with their own personality.

Stress: The Body’s Alarm System

Stress is your body’s response to a demand or threat. It’s a physical reaction triggered by external pressures — like a tight deadline, an upcoming exam or a tense conversation with a boss. Your brain perceives a challenge, and your body responds with the fight or flight response. Your heart races. Your breath quickens. Your muscles tense.

Stress is usually short-term and can be helpful in small doses. It sharpens focus, boosts energy and helps you rise to a challenge. 

Like anxiety, stress becomes harmful when it’s chronic and experienced over a prolonged period of time. When your body is constantly in “alarm mode” it wears you down. Sleep suffers. You become irritable. Your immune system weakens. This is when stress crosses a line and starts to become more than just an occasional motivator — it becomes a health risk.

Key characteristics of stress:

• Triggered by external situations or demands

• Primarily physical: muscle tension, headaches, fatigue

• Can be motivating in the short term

• Subsides when the stressor is removed

Worry: The Mind’s Problem-Solving Tool

Worry lives in your mind. It’s the mental process of going over problems — real or imagined — in an attempt to solve them. Worry tends to be repetitive and often focused on the future: What if I lose my job? What if the test goes badly? What if they’re mad at me?

In small doses, worry can be constructive. It prompts us to make plans and avoid potential pitfalls. But worry becomes unhelpful when it loops endlessly, offering no solutions — only more questions. Unlike stress, which is driven by a present challenge, worry can be driven by anticipation, uncertainty, or imagined threats.

Many people get caught in a cycle where worrying feels like preparation or control. But the truth is, excessive worry rarely leads to clarity — it usually just leads to more worry.

Key characteristics of worry:

• Mental and verbal: internal dialogue

• Focused on future events

• Can feel productive, but often isn’t

• Easier to manage with logical thinking or mindfulness

Anxiety: The Storm That Stays

Anxiety is an emotional state that can linger even when there’s no clear threat. It combines the physical symptoms of stress and the mental churn of worry — and then intensifies them. Where stress and worry are often responses to something specific, anxiety can feel like it comes out of nowhere.

It’s also more persistent and difficult to shake off. Anxiety may show up as a vague sense of dread, an overwhelming fear, or a racing heart with no clear cause. For some, it becomes a constant background hum; for others, it erupts into panic attacks or phobias. It can significantly impact daily life — affecting sleep, relationships, focus, and overall well-being.

Key characteristics of anxiety:

• Both mental and physical

• Often without a clear trigger

• Persistent and hard to control

• Can interfere with daily life and may require professional support

  
  

Putting it all together

Let’s use a real-life example to illustrate the differences:

Stress is the rush you feel as you prepare for a job interview. You’re under pressure, your heart is pounding, and your hands might sweat. Once the interview is over, the stress disappears.

Worry is the stream of thoughts you have the night before: What if I say something stupid? What if they don’t like me?

Anxiety is the overwhelming panic that tries to keep you from going to the interview at all. You might experience extreme emotional and physical responses such as nausea or dizziness. A lingering fear of interviews may persist.

Why This Matters

Understanding the difference between stress, worry, and anxiety empowers you to respond appropriately. Stress might call for rest or time management. Worry might require reframing thoughts or focusing on what you can control. Anxiety might need deeper intervention — through therapy, lifestyle changes or occasionally, medication.

These experiences, though uncomfortable, are a completely normal reaction for your body and - more importantly - are manageable with the right support. The goal isn’t to eliminate stress, worry, or anxiety. That’s impossible and even undesirable - these responses exist for a reason.

Hypnotherapy provides a fast, effective and lasting solution for overthinking, stress and anxiety. If you feel like you need support you're definitely not alone - probably 99 per cent of my clients come to see me for these issues and I love helping them find balance and control.
