Interoception: the hidden sense that shapes wellbeing

There's growing evidence that signals sent from our internal organs to the brain play a major role in regulating emotions and fending off anxiety and depression

If you're sitting in a safe and comfortable position, close your eyes and try to feel your heart beating in your chest. Can you, without moving your hands to take your pulse, feel each movement and count its rhythm? Or do you struggle to detect anything at all? This simple test is just one way to assess your interoception" - your brain's perception of your body's state, transmitted from receptors on all your internal organs.

Interoception may be less well known than the outward facing" senses such as sight, hearing, taste, touch and smell, but it has enormous consequences for your wellbeing. Scientists have shown that our sensitivity to interoceptive signals can determine our capacity to regulate our emotions, and our subsequent susceptibility to mental health problems such as anxiety and depression.
