How Catastrophising & Negative Emotions Change Your Pain (and What to Do About It)

By Grant Frost · Physiotherapist • Last clinically reviewed: 25 June 2026

If you live with chronic pain, you have probably heard the phrase 'it's all in your head'. And if you are like most people, that phrase is deeply unhelpful. It implies your pain is not real. That you are making it up. It sucks.

But here is the thing: your brain and your pain are deeply connected. And that is not a bad thing - it is actually a key to unlocking better treatment. A new narrative review published in the Journal of Pain Research (Jin et al., 2026) explores the mechanisms behind two powerful psychological drivers of pain: catastrophisation and emotions.

The research review finds that catastrophising - that loop of magnifying your circumstances, dwelling on it, and feeling helpless - is not just a personality quirk. It may have a measurable physiological and neurological impact on you and your pain experience. It can increases stress hormones, activate your sympathetic (fight or flight) nervous system, and even interfere with your body's natural pain-killing opioids.

But perhaps the most important message for anyone in pain is this: these mechanisms are modifiable. Your brain is not fixed. And understanding how your thoughts and emotions influence your pain is the first step in taking back control.

What is catastrophising?

Catastrophising is a term that gets thrown around a lot. But in the pain world, it has a specific meaning. The review describes it as a maladaptive cognitive-emotional response characterised by three core components:

The review highlights three complementary models that help explain catastrophising:

• The Cognitive Model: This suggests catastrophising is a maladaptive appraisal process. You overestimate the harm of pain and underestimate your ability to cope. It is an automatic cognitive error. Studies show that low self-efficacy (belief in your ability to cope) is a key driver. One study reviewed consisted of 430 chronic pain patients, and found the more pain people experienced, the more likely they were to worry that something was seriously wrong. This was partly because they had less confidence in their ability to manage their symptoms.
• The Coping Model: This views catastrophising as a social-communicative strategy. Expressing distress - verbally or non-verbally - can elicit empathy and support from others. In the short term, this can reduce distress. But over time, it can become maladaptive, straining relationships and reinforcing the pain cycle if sympathy-seeking behaviours persist.
• The Trait Model: This conceptualises catastrophising as a relatively stable tendency, linked to personality traits like neuroticism. Twin studies suggest a significant genetic component, with genetics accounting for 37% of the variance in catastrophisation.

How catastrophising and emotions affect pain

This is where the science gets really interesting. The review identifies several key mechanisms by which catastrophising and negative emotions influence pain perception.

Shared Mechanisms

Both catastrophising and negative emotions like anxiety and depression share common pathways:

• HPA Axis Overactivation: This is your body's stress response system. Chronic activation leads to elevated cortisol, which can sensitise pain pathways.
• Sympathetic Overdrive: This is your 'fight or flight' response. It increases heart rate and arousal, promoting pain sensitivity.
• Reduced Endogenous Opioids: Your body produces its own pain-killing chemicals - endorphins and enkephalins. Catastrophising and negative emotions interfere with this system, reducing your natural pain resistance.
• Weakened Prefrontal Regulation: The prefrontal cortex is your brain's 'brake pedal' for pain and emotion. When it is weakened, limbic overactivation (emotional brain) amplifies pain perception.

What Makes Catastrophising Unique

Although catastrophising and negative emotions often go hand in hand, researchers have found that catastrophising is linked to a unique pattern of communication between different parts of the brain - the salience network and the default mode network.

The salience network detects and prioritises important stimuli (like pain). The default mode network is involved in self-referential thought and thinking. When these networks are hyperconnected, pain signals become integrated with self-focused, negative thoughts, amplifying attention to pain and making it feel more threatening.

This explains why someone who is catastrophising can't stop thinking about their pain - their brain is wired to do so.

The power of positive emotions

The review also highlights the protective role of positive emotions. Happiness, joy, and contentment are not just the absence of negative feelings - they actively reduce pain intensity.

Positive emotions work through opposite mechanisms:

• Increased parasympathetic activity: This is your 'rest and digest' system, promoting relaxation and pain inhibition.
• Enhanced endogenous opioid release: Positive states trigger the release of your body's natural pain-killers.
• Improved descending inhibition: Positive emotions strengthen the connection between the anterior cingulate cortex and the periaqueductal grey, enhancing top-down pain control.

This is not about 'positive thinking' as a cure. It is about understanding that your emotional state has a direct, biological impact on how you experience pain. Activities that promote positive emotions - social connection, hobbies, time in nature - are not just 'nice to have'. They are a legitimate component of pain management.

A clinical perspective: catastrophising in practice

Now, I want to share something I have observed consistently in my clinical practice over the years.

When I assess someone with persistent pain, the degree of catastrophising - whether it is dramatic or more subtle - tends to be a consistent predictor of how much they are suffering. And I don't just mean the intensity of their pain. I mean the whole experience: how much it disrupts their life, how anxious they feel, how hopeless they seem.

I have seen this in people with 'minor' injuries who are completely disabled by their pain. And I have seen it in people with 'severe' injuries who are functioning remarkably well.

What I have found is that the people who do best are not necessarily those with the 'best' injuries. They are the ones who, despite their pain, maintain a sense of agency. They believe they can cope. They don't magnify the threat. They don't ruminate. They stay positive and look at things through a productive lens.

Conversely, I see people who use language like:

• "My back is destroyed."
• "I'm terrified to move."
• "Nothing will ever help."

These are the people who struggle the most. And this is not a judgment, it's just an unfortunate reality for so many people. Their brain has learned to be afraid or intimidated by their pain. And that fear can drive a cascade of physiological changes - stress hormones, sympathetic "fight or flight" activation, reduced opioid function - that may actually make pain worse.

This is not 'in their head' in the sense that it is imaginary. It is 'in their brain' in the sense that their nervous system has become sensitised. And the good news is that the brain can change.

The review supports what I see clinically. The cognitive model tells us that self-efficacy is a key driver. The neural evidence shows that catastrophising alters brain connectivity. The physiologic evidence shows it changes hormone levels and pain inhibition.

This is not about blaming you. It is about understanding the full picture so we can provide better care.

Interventions that help

The review identifies several evidence-based interventions that can blunt the mechanisms underlying catastrophisation and negative emotions.

1. Mindfulness and Relaxation Exercises
Mindfulness has been shown to reduce HPA axis activation and, to a lesser extent, sympathetic activity. It helps you observe your thoughts without getting caught up in them. Deep breathing exercises can activate the parasympathetic nervous system.

2. Cognitive Behavioural Therapy (CBT)
CBT is one of the most effective interventions for altering maladaptive thought processes. It helps you identify and challenge cognitive distortions, reducing catastrophising and its physiological effects.

3. Yoga
Yoga has been associated with reductions in both sympathetic activity and HPA axis activation. It combines movement, breath, and mindfulness - a powerful trio for pain management.

4. Activities That Promote Positive Emotions
Engaging in social interactions, hobbies, or activities that bring you joy can enhance endogenous opioid release and improve pain inhibition.

• Assess coping strategies early. Don't wait until you're in crisis. Understand how you cope with stress and pain as early as possible.
• Identify individuals at risk of catastrophising. Simple questionnaires like the Pain Catastrophizing Scale (PCS) or Neuroticism Scale can help identify those who might benefit from early intervention.
• Focus on positive outcomes. Contextual factors - like patient-centred communication and emphasising what can be done - can induce effects associated with enhanced endogenous opioid release.
