This is an example of interoception, which is one of the body’s eight sensory systems. It’s a key one for emotions in that it helps us build self-awareness. When I say, “I have butterflies in my stomach,” you might know that feeling and understand that I’m feeling nervous or excited. What if we could identify what’s happening inside our bodies for more emotions? What if we knew what disappointment or embarrassment felt like? How rad would it be to notice sadness or anger before it became all-consuming?
