homeostasis

/ˌhəʊ.mi.əʊˈsteɪ.sɪs/
IELTSAcademic
noun

the process by which a body or system keeps its internal conditions steady, even when outside conditions change. In biology, it often means keeping temperature, water, and other levels balanced.

  • Exercise can disturb your body's homeostasis.
  • The body works to restore homeostasis.
  • Homeostasis keeps internal conditions stable.

Adinary Nuance

Homeostasis is more specific than balance. It means a system actively keeps itself stable, not just that things are equal. It is also more technical than words like stability or equilibrium, which can be used more broadly. In science writing, homeostasis is the best choice when you mean the body's self-correcting control.
