We also have sensory systems that tell us what is going on inside our body. This is called interoception, and it creates our sense of, for instance, being thirsty, hungry, or short of breath. All the sensory inputs from the outside world and our inside world give continuous feedback to the brain so that the proper systems can be activated to keep us healthy and safe. If we’re thirsty, we seek water; if we’re hungry, we seek food; if we sense danger, we mobilize our stress-response systems.
