Homeostatsis - or Balance

I keep hearing the words homeostasis in relation to health. Please help me understand what that means.

A synonym for homeostasis is balance. Pure and simple is means balance. Live a balanced life if you want to be healthy. Robert Fulghum, author of All I Really Need to Know I Learned in Kindergarten, put it this way: “Live a balanced life—learn some and think some and draw some and paint some, and sing and dance and play and work every day some.” It means you have a handle on the various key elements in your life and do not sense that your brain and your heart are in a tug of war. Typically, you’re motivated, think clearly, and are calmly grounded in reality, enjoying most if not all aspects of your life. Likely you’ve seen the pendulum of a grandfather clock swinging back and forth and back and forth. It can be comforting, almost hypnotic. A pendulum that has stopped swinging means the clock has stopped functioning. An erratic pendulum tends to wobble, swing wildly from side to side, or crash into the glass and stop. Much like a well-running grandfather clock, the brain works best in balance—when everything is working congruently. Think of life as your balance beam—each person has one.
