“These matters of the heart are University of Sussex researcher Sarah Garfinkel’s speciality. Over the past several years, she’s found evidence that the beats of your heart — and your awareness of that rhythm — shapes everything from anxiety to racism to stock trading.”
“Every time the heart projects blood, it pings pressure-sensitive receptors that send signals to the head . . .The brain essentially flashes each time the heart beats,” she says, “and the degree of signal in the brain corresponds to how fast and how hard the heart is beating, so the brain is in dynamic, constant communication with the heart,” especially the amygdala and thalamus, regions associated with fear and pain perception, among other roles.”
“. . . your brain, but it also represents the activity of our organs, and whether you realize it or not, these sensations guide the way you navigate the world. Recognizing this marks a shift in how neuroscience could be approached, she says: Rather than separating the brain and the body, the brain is seen as embedded within the body. Doing so could offer new treatments for things like anxiety, where drugs could target bodily processes as well as those in the brain, or behavioral techniques like meditation that make people more bodily aware.
“I think the general public kind of knows it instinctively, they know if they exercise they feel better, they know their mood changes, their cognition and memory increases; people who meditate also see changes in their cognition and emotion,”
“One of those primary somatic tools is interoception, or the felt sense of the activities of your organs. Garfinkel (and other neuroscientists and social psychologists) are finding that bodily sensations are key ingredients in emotional experiences, and that how fine-tuned of an internal “feeler” you are predicts your ability to stabilize them.”
Making decisions can be emotionally loaded — the decision feels right or good.
” More hopefully, heartbeat awareness looks to be trainable: Garfinkel says she has yet-to-be-published data suggesting that you can teach people to align their interoceptive self-confidence and their accuracy, reducing the unrecognized sensations and the anxiousness they promote . . .”
