From Pathfinder Wiki

Altitude acclimatization has two stages. Overnight, the body can adjust its carbonic acid balance, and substantially improve its performance. Over four to six weeks, the body can grow more blood cells, strengthen the heart and make other tissue changes. Above 5,500 meters18,000ft, further altitude exposure weakens, rather than strengthening one's acclimation.
