We've been trained to dominate our bodily feelings with thinking. This may be necessary, to a point. But it has become common to treat bodily communication like a fascist dictator treats unwanted criticism.
The body is inarticulate, inefficient. Listening to it will slow down progress, and, we intuit, lessen our most powerful motivation, unconscious drivenness. Exposing this is reason enough to listen. A truer, less harmful source of motivation will emerge.
But I acknowledge how hard it is to value bodily communication. It can feel like listening to a small child ramble on about an imaginary friend when there's a grease fire on the stove top. But most of the time urgency is an illusion, a defense of the comfortable status quo. Which is only comfortable because it's familiar, in reality it's a tyranny of thought, an imbalance of power.
Though there is much wisdom in our bodies it can be hard to access. But think of it this way, if you merely feed and cloth your toddler, focusing instead on productivity and efficiency, your toddler is going to act out, and maybe even get sick. This is going to interfere with your productivity, and worse, change your experience of your child from a delight to a nuance.
Likewise, your body will keep speaking (acting out), no matter how long you ignore it. Unappreciated bodies have been known to use sickness as a way to get attention.
Listen for how often you use adversarial language when referring to your own body. It does, after all, seem to have a "mind" of its own, it can feel like a willful child. Even so, it's needs are real and the quality of your thinking is affected by the condition of your body.
There are books about how-to listen to the body. I've found them mostly unhelpful, except as motivation to value the practice. Like so many things, one really learns through practice alone.
On this day of The Year of Living Slowly, I'm reminded that listening to the soft knot in my stomach was worth a few minutes of silence. I was much more patient and gentle with the unhappy and defensive customer that was causing the anxiety, once I acknowledged it and used the awareness to prepare.
