spending too much time in this zone can also trigger an increase in stimuli that your nerve endings detect and interpret as a painful sensation and report it up to your brain. The more those nerve receptors pick up potentially noxious stimuli, the more indication your brain gets that there might be a reason to create pain. As you might recall from the pain chapter, your brain can get more proficient at feeling pain because those nerves are being stimulated so frequently, which means an acute event can turn into a chronic tissue issue where pain then becomes more consistently present.
