Modern science almost exclusively associates mental health with the brain. While this is true to an extent, it doesn’t quite tell the whole story. New research into interoception indicates that the rest of the body may also have a significant part to play with what’s going on inside our heads – we explain more in this post.
Making Sense of It All
Exteroception. You may not have heard of this term, but you’ll almost definitely be familiar with the senses it describes:
These are the things that help us make sense of the world around us. We also have a sixth sense, called proprioception. This is the awareness of where one body part is in relation to another. It’s this that allows us to clap our hands with our eyes closed.
And then there’s interoception, the ability to feel what’s going on inside the body. We may associate these sensations with emotions like anxiety, anger and excitement. Crucially, interoception can involve the ability to pinpoint exactly where these feelings are coming from, for instance the stomach, chest or arms. According to new research, this ability to feel inwardly is linked to improved mental health.1
British neuroscientist and Professor of Psychiatry and Consciousness Science Dr Sarah Garfinkel has been studying the field of interoception for more than a decade. In a New Scientist article published in 2020, Dr Garfinkel explained: “Our thoughts, feelings and behaviours are shaped in part by the internal signals that arise in the body.”
The internal signals she refers to are both electronic messages that flow between the brain and our organs and tissues and chemical messages such as hormones. Dr Garfinkel’s work has exciting implications for mental health, and she and her colleagues believe improving your internal awareness may help to alleviate specific conditions linked to mental health, like anxiety and depression.2
How to Improve Your Interoception
To sharpen our sense of interoception, we need to focus on relaxation techniques that regulate the body’s processes, things like heart rate, breathing and digestion. The aim is to retrain how the body reacts to certain signals, allowing us to experience more pleasant feelings when before we may have reacted with emotions like anger and anxiety. Here’s a straightforward four-step process you can try yourself:
- Notice your body’s signals – try to sense important signals from your body, such as changes in heart rate, breathing and digestion.
- Learn to regulate bodily feelings – when you feel your heart rate rising, chest tightening or stomach doing summersaults, use breathing techniques to calm and soothe your body.
- Don’t worry about the feelings – calm yourself with the knowledge that you can regulate them.
- Focus on the outside world – once you’ve acknowledged your inner feelings and have started to proactively regulate them, it’s important to then return your attention to the outside world.
