She acclimatizes quickly to high altitudes, so mountain hikes don't bother her.

After a week at high altitude, she finally acclimatized and could breathe more easily.

The acclimatized seedlings withstood the sudden frost better than the greenhouse plants.

The acclimatizational demands of high-altitude research required scientists to undergo gradual exposure and close physiological monitoring.
