The human body is a complex, well-oiled machine that knows which function it needs to make active at any given moment. And among the functions, are those that no one can consciously control. They are activated without asking us for permission and all we can do is follow the brain’s orders. We’re talking about protective functions such as coughing, sweating, and shivering; as well as functions that we don’t know everything about like yawning and getting the chills.
