Health

Health is the fundamental condition that an entity needs to survive. Health can be recovered by healing, through natural regeneration, or by using status effects.

Players can recover health naturally by having their hunger at least 18 ( × 9) and the gamerule naturalRegeneration is set to true, or through status effects.

Horses, donkeys, mules, skeleton horses, zombie horses, llamas, trader llamas, camels, camel husks, allays, happy ghasts, and the wither‌[Java Edition only] are the only mobs that regenerate health naturally over time.
