Understanding What a Hormone Is
A hormone is a chemical messenger produced by glands in the body. These messengers travel through the bloodstream to organs and tissues, telling them what to do.
What Hormones Do
Hormones control many essential functions, including growth, mood, metabolism, sleep, stress responses, and reproduction. They help keep the body balanced and working properly.
Where Hormones Come From
Hormones are made by the endocrine system, which includes glands like the thyroid, pancreas, adrenal glands, and pituitary gland.
How Hormones Work
When a hormone is released, it binds to specific receptors in target cells. This triggers a response, such as releasing energy, adjusting temperature, or changing mood.
Examples of Common Hormones
Insulin controls blood sugar, cortisol manages stress, melatonin regulates sleep, and estrogen and testosterone support development and reproduction.
Why Hormones Are Important
Even small changes in hormone levels can affect health, mood, and energy. A balanced endocrine system is essential for overall well-being.
The Simple Takeaway
Hormones are chemical messengers that guide and control your body’s functions. They keep everything in balance, from energy to sleep to mood.
