The word hormone is derived from the Greek word messenger. There are more than 100 hormones in your body and they are always communicating and sending messages to each other in a type of orchestral symphony. These hormones need to be balanced so your body can achieve homeostasis; the same is true for every instrument in an orchestra to achieve the desired harmony and sound. If one instrument is out of balance or off-key, it creates a cascade and affects the entire orchestra.
