What does that even mean lol. At sea level you don't experience it, the air is not 100% oxygen you know. And even when you get at sea level from high altitude, if you have adapted well and thoroughly, the good effects last from months, including being leaner and the improved myopia.
Yes but it is stressful to return to a less ideal environment.
