  1. Head first, like a dolphin
  2. Feet first, head up ✔
  3. Flat on your back

Why: Air rises up your ear tubes and mucus drains down. Studies found the common Valsalva move (pinch your nose and gently blow) takes 50 percent more force when you are head down.

Huh, didn't know that: Pulling yourself down a descent line also helps you stop quickly if your ears feel pressure.
