Last week, I shared a bit about four interesting studies that look at pain. But I couldn’t stop at just four! So today, we’ll look at another four of the latest studies around how pain works, and what we can do about it.
Mindful people experience less pain
Some people just don’t seem to experience pain as much as others. One study has suggested that part of the reason why is mindfulness.
What is mindfulness? It’s being in the present moment, rather than the past or future. When you are mindful, you are an observer of your experience rather than reacting with emotions and judgements.
76 volunteers with varying levels of innate mindfulness took part. Their brains were scanned as they were exposed to painful heat of around 49 degrees Celcius (aka a typical Aussie summer day, right?)
The scans reveal that people who were more mindful did not activate an area of the brain called the posterior cingulate cortex as much as those who were less mindful. Those who reported high pain levels had a greater activation of the cortex.
The researchers concluded that mindful people are less caught up in the experience of pain.
You can’t change your in-born level of mindfulness, but there is other research that suggests that mindfulness practices can help with pain. This might explain why!
Being hungry shuts off perception of pain
Pain is a valuable experience for the human body. Without it, we would damage our bodies without realising the consequences! But chronic pain can lead to lethargy and exhaustion. So what if nature gave us a way to suppress chronic pain temporarily?
Turns out, nature might have done just that. Researchers have pinpointed a group of 300 brain cells that prioritise hunger over chronic pain. They found that hungry mice would respond to acute pain, but were less fussed about longer-term inflammatory pain compared to well-fed mice.
Further experiments revealed that the neurotransmitter NPY can block the inflammatory pain response when needed. This is a new area for more research, but it could reveal ways to inhibit chronic pain without shutting off acute pain.
'Tuning' the brain can alleviate pain
Previous research has found that alpha waves are associated with relief of pain from a placebo effect, and can influence how different parts of the brain process pain. So researchers looked into whether ‘tuning’ the brain to alpha waves can reduce pain.
The experiment involved flashing light or playing noise that were in the alpha range. Both of these interventions significantly reduced intensity of pain. The researchers are now looking into how effective these are for different pain conditions.
It’s early days. But soon, you could be watching YouTube videos or listening to meditations in the alpha range that are able to reduce your pain!
Does an exploding brain network cause chronic pain?
Hyperactive brain networks could be why people with fibromyalgia experience hypersensitivity. Their brain networks are primed to react with rapid and system-wide responses to minor in response to minor changes. This is known as explosive synchronisation.
The researchers looked at the electrical activity of women with fibromyalgia. There was a strong correlation between the hypersensitivity of the brain and the intensity of pain reported by the women.
This suggests that a chronic pain brain is electrically unstable and sensitive. So the next time someone asks you about your fibromyalgia, tell them it’s your exploding brain network!
In case you haven’t figured out, supporting people with chronic pain is my passion. If you’re looking to work with a health professional who will work with you on your journey to recovery, book a myotherapy appointment today.
Did you know I'm upgrading my qualification?
I'm currently studying my Bachelor of Health Science (Myotherapy) at Endeavour College of Natural Health!
The Bachelor of Health Science gives me more advanced techniques, including mobilisation, assessments, pathology and clinical sciences, pain neuroscience, foundations of human nutrition, further corrective exercise prescription, and lots more!
Any of you who know me, know I'm a total nerd about this stuff, and I'm very excited to bring new skills week by week back into my clinic.
I start on campus classes in March 2018. I'll be studying all day from 8am through til 6pm on Thursdays.
My available clinic hours from March 2018 will be:
Monday - 9am-7pm
Tuesday - 9am-7pm
Wednesday - 9am-7pm
Thursday - closed
Friday - 9am-7pm
Saturday - closed
Sunday - closed
Want to book your next appointment? I look forward to seeing you soon!
