Pilot body under pressure: study reveals Altitude's hidden toll

This study looked at how low oxygen levels (like at high altitudes) affect pilots' bodies and their ability to fly. Seventeen healthy adults who meet Navy body standards were tested in a flight simulator at normal oxygen, then at simulated 8,000 and 12,000 feet, and during a gradual climb. Researchers measured heart rate, blood pressure, oxygen levels, skin responses, and neck muscle activity while pilots performed tasks like maintaining altitude and landing. The goal was to understand which body systems are most affected by sudden vs. gradual oxygen drops.
