Chemical messengers produced by the endocrine system that convey vital information among various cells and tissues, hormones play a crucial role in controlling most major bodily functions. In fact, hormones are involved in everything from hunger, metabolism, and growth to reproduction, the immune system, and mood. You probably recognize the names of some of the major hormones.
Estrogen is the primary sex hormone for women. For men, testosterone is the main sex hormone. Many people know that melatonin plays a role in sleep. Cortisol also enjoys a fair amount of recognition. It’s sometimes called the stress hormone, but it is involved in far more than just the stress response. These are just a few of the many hormones that must work together harmoniously to keep the human body functioning smoothly.
