The word ‘homeostasis’ has Greek origins: ‘homoios’ means equal or similar, and ‘stasis’ means stillness or stability. At its core, homeostasis is about achieving stability, equilibrium, or balance throughout the body. Maintaining homeostasis allows the body to create the optimal conditions to ensure our health and wellbeing. It is an overarching physical process that keeps our internal environment balanced, adapting to our external environment in a world of constant change.
