Hormones are the body's chemical messengers, orchestrating virtually every physiological process from metabolism and mood to growth and reproduction. The endocrine system operates as an intricate feedback network where small imbalances can cascade into significant health issues. Understanding how lifestyle factors — sleep, nutrition, exercise, stress, and light exposure — influence hormonal balance provides a powerful lever for optimizing overall performance and well-being.
