Sunburn in the shower – Neuroscience nugget No. 15

As an educational strategy, providing contrasting information is a known and effective way to promote optimal learning in pain physiology. In the often delicate discussion about central sensitisation, providing some knowledge about peripheral sensitisation allows a contrast with the more complex features of central sensitisation. Plus, it probably helps that you can demonstrate to the learner that you know about peripheral sensitisation and don’t think everything is in the head!

The nugget might go something like this:

“Remember back to when you were once sunburnt… take a moment to reflect… and then remember what happened when you got into the shower… and how much even a warm shower hurt… much of this is due to sensitive nerve endings in your skin – the nerve endings become sensitive to heat and even the pressure from the water. This is peripheral sensitisation: it’s very common and it’s due to changes in your body tissues. Another example (remember to give two examples when contrasting, if you can) is when you have a sore throat and then swallowing hurts – again, peripheral sensitisation – a great protective process.

Peripheral sensitisation usually behaves quite simply. Notice how your sunburn hurts the moment you get in the shower, but settles when you get out, or when your throat is sore, multiple coughs make each cough a little worse. Symptoms are usually a bit more predictable when you contrast them with the features of central sensitisation.”

Understanding these contrasts forms part of a broader pain physiology framework. It helps learners grasp that peripheral sensitisation is a normal, tissue-based process, while central sensitisation involves more complex changes within the nervous system. Highlighting both gives a clearer, more compassionate picture of how pain systems adapt – and sometimes over-adapt – to protect us.

For clinicians and educators, revisiting pain physiology through relatable examples like these can strengthen communication and enhance patient understanding. It reminds us that effective pain education is not just about what’s happening in the brain, but about connecting physiology to experience.

Neuroscience Nuggets are short pieces of biological information based on a statement or metaphor that can be used as educational analgesia, explicit education or part of overall storytelling. We have collected over 100 of these as part of a pain storytelling taxonomy. Find the full taxonomy in Explain Pain Supercharged (Moseley and Butler, 2017).

There are plenty of NOI courses coming up before Christmas, all of them full of nuggets. Check them out on www.noigroup.com
