7 Days to Functional Breathing

Day 4 / 7

The Carbon Dioxide Paradox

More air isn't the same as more oxygen. Here's why carbon dioxide matters.

  • Video lesson with Patrick McKeown
  • 6–10 minutes

Today's practice

A few times today, check whether your breathing is quiet, light and effortless. Notice frequent sighing or yawning.

Key points

  • Carbon dioxide helps regulate your breathing and helps release oxygen from your blood into your tissues.
  • At rest, breathing more than your body needs lowers carbon dioxide and doesn't add oxygen.
  • During exercise your body needs more air, and breathing more is right. The goal is breathing that matches what your body needs.
