A hormone is a chemical in the body that helps control different functions like growth and mood. It is produced by glands in the body and travels through the bloodstream to different parts of the body. For example, some hormones help control our appetite and metabolism, while others regulate our sleep-wake cycle. You might hear about hormones when talking about puberty, pregnancy, or medical conditions like diabetes. It's important to have a balanced level of hormones in the body to maintain good health.
