1393: Andrew Herr | Why Travel Leaves You Wrecked (and How to Fix It) — The Jordan Harbinger Show

Andrew Herr explains that flying causes "flight inflammation" due to rapid pressure changes, reduced oxygen, and exposure to bleed air, leading to fatigue, blood clots, and disrupted sleep. He advises flying on 787s or A350s for better cabin pressure and recommends using light, meal timing, and supplements to reset circadian rhythms. The episode also covers why airplane food is salty, the risks of fume events, and how to mitigate dehydration and jet lag effectively.
