In the scenario above, the balancing act between our different biological systems can be imagined as a giant hanging mobile. The body will naturally tilt and sway various functions to send support to where it's needed, but will always strive to return to its original position—a homeostatic state. Although this focus on the immune system is to the detriment of other functions, over time, the body will naturally return to its balanced state—once the cold has passed. Now, usually, all of these systems “talk” to each other, ensuring an even spread of resources. However, it isn't always possible for the body to maintain a balanced state; but this isn’t necessarily a bad thing.
