What is a hormone?

The hormone is a biologically active substance of organic nature that has a regulating effect on the metabolism and physiological functions of the body. In this article we will describe in more detail what a hormone is, and also consider its role in the process of life activity.

How do hormones work?

By and large, the role of hormones is to ensure the stable operation of the body. With a certain external or internal stimulus, the production of the corresponding hormone begins or, on the contrary, is suspended. The hormone control center is the hypothalamus.

Types of hormones

Hormones are not only in humans, but also in animals, plants and even insects. There are a lot of types of hormones, but in a broad sense there are two types of hormones - steroids and peptides. Steroid hormones are produced by the adrenal glands and sex glands from cholesterol. A prominent representative of steroids is cortisol, the so-called stress hormone, which causes the body to respond to a potential threat. Peptides regulate metabolism.A typical representative of peptides is growth hormone, which allows the body to burn fat and build muscle. Read about this hormone in the article What affects growth.

Hormonal disorders

Disruption of hormonal levels is a serious problem. A person with an impaired hormonal background is constantly annoyed, cannot resist stress, and quickly gets tired. In addition, this problem causes metabolic disorders, decreased sexual desire, obesity, etc.
