Your body at 35,000 feet is in a weirder state than you think
At cruising altitude your heart rate runs 10-15 BPM higher. Blood oxygen saturation drops to 89-94%, which would trigger supplemental oxygen for a ward patient. Cortisol climbs. Your body stays mildly stressed for hours after landing.
Layered on top of that, you're sitting in one of the densest wireless environments outside of a data center. Cabin WiFi, Bluetooth pairing constantly, seatback screens, laptops, phones, all reflecting off the metal fuselage rather than dissipating.
Jet lag as a concept was named in the 1970s, before most of this signal layer existed. It doesn't cover the altitude stress part or the exposure part.
