The Strange Case of Interoception and Resilience or How to Become a Superhero



The 2024 Global Year will examine what is known about sex and gender differences in pain perception and modulation and address sex-and gender-related disparities in both the research and treatment of pain.

Steel is a very resilient material: it has the capacity to absorb the energy produced by a hit without breaking. Translating this original definition of resilience into the Psychology field, a person is resilient when they can cope well with stressful situations. No wonder Superman is called “man of steel”!

Back to more scienc-y stuff, recently Haase and colleagues [1] supported the idea of a link between resilience and interoception. Specifically, they found that people who are less aware of their own body’s internal changes (low interoception levels) are also less able to cope with stress (low resiliency levels). Hence, for example, if you are able to predict you will have the flu from small changes in your body, you might also be very good at managing stressful situations. The authors’ hypothesis is centred on the concept of body prediction error, i.e. the amount of error yielded by the comparison between a current interoceptive state and an anticipated or predicted state. Thus, the smaller the error, the better the performance. Hence, people more aware of their body state (i.e. more skilled in interpreting interoceptive signals) are also better performers and, in turn, they are better in coping with stressful situations than people who are less aware of their body state. For example, elite athletes are very good at interpreting their own body signals in order to maintain their activity level within both biomechanical and metabolic limits. Ultimately, this ability enables them to cope with highly stressful situations without getting hurt. As often happens, the relation of causality between body awareness and being an athlete[*] is not clear, but nonetheless a link does exist.

Furthermore, in low resilient participants (as distinct from normally and high resilient participants) a higher activation of thalamus and middle insula has been found during the anticipation phase of an aversive stimulus and during the administration of the aversive stimulus itself. To clarify, the “aversive stimulus” was a simulated momentary condition of breathing discomfort artificially induced by a machine.  An aversive event provokes a cascade of internal body changes (such as increased heart rate, vasoconstriction, and sweating) that are interpreted by the brain. In particular, middle and posterior insula have been identified as primarily interoceptive cortex. People with high interoceptive levels do not really need to allocate lots of mental processing resources in order to efficiently interpret these signals. Consequently, these people can employ those resources for other tasks (i.e. being able to score a goal even if tired and hearing the opposing supporters’ boos). On the other hand, people needing to gather more mental resources to deal with the physiological (and psychological) consequences of an aversive stimulus, will probably fail or, at least, be less efficient in completing a task. For instance, low resilient and anxious people usually need to allocate a great amount of processing resources to interpret their own interoceptive signals. However, this does not mean that people with low levels of interoception are doomed! Low resilience participants involved in this study were well functioning individuals in their everyday life, confirming that, in fact, human beings can develop and nurture alternative strategies to face everyday challenges despite their own natural predispositions.

Interestingly, resilience has a crucial role in pain [2]: being resilient has been proven to be a positive characteristic for both recovery and acceptance processes [3-5]. Given the close link existing between interoception and resilience  [1], and that chronic pain patients have indeed a poor representation of their affected part (see, for example [6]), low interoception/low resilience might have a crucial role in the development and maintenance of chronic pain. In other words, perhaps it is possible that when generally low interoceptive/low resilient individuals experience a stressful situation (e.g. a sprained ankle), they are unable to efficiently deal with the corresponding interoceptive signals. For instance, jogging causes a physiological increase in heart rate. Sports people know that it is normal, and this specific interoceptive signal has little impact. On the other hand, people not used to sports might be alarmed because in their experience an increase in heart rate means “you are fatigued or you are having some troubles with your heart: you should rest”. Thus, the same interoceptive signals (increase in heart rate) will be interpreted as “irrelevant” by the sports people (potentially highly interoceptive) and as “dangerous” by the newbies (potentially poorly interoceptive), leading the latter to stop. Similarly perhaps the interoceptive signals are overwhelming and confusing to people in pain with low interoception levels. An inefficient interpretation of those signals affects the ability to cope with the aversive stimulus that induced such an interoceptive response (poor resilience). They might also unconsciously go back many times to check their body signals in order to try and make sense of them. People with high interoceptive abilities, instead, would know their own body so well that they would easily interpret those signals. The resources needed for the signal’s interpretation are obviously subtracted to other tasks, for example coping better with a stressful painful situation.

The positive effects of practice such as mindfulness on pain fit very well in this interesting link between interoception and resilience. Mindfulness increases one’s own body awareness  –  we can argue that it somehow trains people to be more aware of the interoceptive signals, to become familiar with them. We now know that increased interoceptive abilities leave more resources to other tasks, such as coping with pain. Indirectly, thus, increased body awareness might be able to improve resilience, by unloading the overwhelmed interoceptive system.

New research will clarify the clinical relevance of the link between interoception and resilience. In the meantime, even if we were not born on Krypton, we can still call ourselves women and men of steel. It looks like we just need a bit of practice.

About Valeria Bellan

Valeria BellanValeria obtained her degree in Cognitive and Neuro Psychology at the University of Pavia, Italy. She worked for one and a half years as a psychologist at Niguarda Hospital in Milan with children and adults affected with Focal Epilepsy and Parkinson Disease.  Since then she has finished her PhD (entitled ‘Body representation, body localisation and body size perception: a study of bodily modulations’) at the University of Milano Bicocca under the supervision of Dr Alberto Gallace and now is with the BiM team as a post doc fellow.

Valeria’s work investigates the processing of tactile and painful stimuli in the context of multisensory integration and body representation. In particular, Valeria uses the Mirage box to perform bodily illusions in order to investigate self-localisation in chronic pain (especially in people with CRPS).

Valeria used to practice track and field, running the 400 metres and recently achieved her aim of running a marathon. As Helen (Gilpin) can confirm she has a special ability to open containers and key rings. What she misses most about Italy is having breakfast with biscuits but is enjoying learning the Aussie lingo and developing quite an Aussie twang!
