Flying exposes you to more cosmic radiation than most people realize.
If you travel a lot, save this and read before your next flight.
One of the biggest takeaways here:
Air crew get the highest mean annual radiation dose of any U.

The concern isn’t just “being in the air”—it’s the altitude and cosmic rays.
A simple habit mentioned here is increasing vitamin E around flight days.
This doesn’t replace medical advice, but it may make you think differently about what repeated flying could mean for your health.
Have you ever looked at flight time through a health lens?
