Dr Chris Barker, who works in pain management, says this area of medicine is still developing.
He says there is a growing understanding of the importance of the vagus nerve, but while there is “clear evidence” around the impact an unbalanced nervous system can have on everything from our mental health to our heart rate and our ability to digest food, it does not mean we have the all the answers – yet – on how to correct the problems.
“It’s really rational to focus on something that’s problematic – and try to fix it.
“Our bodies are, of course, really complex, and sometimes the problem we see may be part of an imbalance in a wider system.”
It’s not about going to extremes, he says. It’s “about figuring out what works for you” – and that can often take time.
It’s worth noting if you have underlying heart or respiratory conditions you should seek medical advice before trying to rebalance or stimulate your nervous system.
Now, several years after experiencing burnout, Lucy, 47, is launching her own business helping others to build emotional resilience and confidence.
She still uses her devices daily, meditates, and regularly checks in with how she is feeling. “The devices make me rest and switch off.”
But she agrees it is difficult to know whether it’s the devices making the difference or the fact she is taking some much-needed time out.
There is a lack of robust scientific evidence behind these devices but for Lucy, they’ve played an important part in her recovery. Understanding her nervous system and the importance of the vagus nerve has empowered her, she says.
“It’s helped me take ownership of my own mental health and wellbeing, and that’s massive.”
