Why Airplane Cabins Are Drier Than the Sahara

Ever wonder why you always get a scratchy throat after flying? This episode breaks down the surprising physics and engineering behind airplane cabin air — from bleed air systems and HEPA filter gaps to why humidity plummets to Sahara-beating lows. We explore how dryness compromises your immune defenses, whether flight crew actually build resistance (spoiler: it's complicated), and why the Dreamliner's bleed-less design still can't solve the moisture problem. If you've ever felt like a flight left you sick, this explains why. Episode #202975 — open it directly at myweirdprompts.com/202975
