Also see the "somatic marker hypothesis"[1][2] by neuroscientist, Antonio Damasio. It's about how various internal body "markers" deeply influence decision-making. I first read it in his 1991 book, Descarte's Error.
Quoting from here[1]:
"Somatic markers" are feelings in the body that are associated with emotions, such as the association of rapid heartbeat with anxiety or of nausea with disgust. According to the hypothesis, somatic markers strongly influence subsequent decision-making. Within the brain, somatic markers are thought to be processed in the ventromedial prefrontal cortex (vmPFC) and the amygdala. [...]"
Although, experimental evidence is not as yet as robust as it needs to be. See the "Experimental evidence" and "Criticism" sections here[1].
