the.com/acclimatization

Your body quietly rewriting its own settings so the new normal stops feeling insane.

means The process by which an organism gradually adjusts to a new climate or environment, until conditions that once felt extreme start to feel routine.

from Built in the 1700s–1800s from 'acclimate,' itself from French 'acclimater' — 'ad-' (to) plus 'climat' (climate, from Greek 'klima,' meaning slope or region, tied to the slant of the sun at a given latitude). So at its root, the word literally means 'toward the slope of the sky' — fitting, since acclimatization is your body figuring out exactly where on earth it's standing.
