The hypothalamus is a small hormonal gland, the size of a pea, located in the center of the brain. Their task is to control and regulate each and every gland body functions, such as energy levels, sleep cycles, temperature, blood pressure, muscle function, immune system, among other functions. This gland depends on external factors and receives all information from every part of the body. Parallel changes and resets the functions of our body. Once filtered information, the hypothalamus sends orders to the body in two ways: the autonomous nervous system, through the spinal cord, the pituitary gland and, through the endocrine system.
