Breath

Points clés

• Bien respirer compte autant que bien manger ou bouger
• Respirer par le nez filtre, réchauffe l'air et optimise chaque bouffée d'oxygène
• La plupart des gens respirent trop : ralentir et alléger nourrit mieux le corps
• Around 5 to 6 breaths per minute calms the nervous system and steadies the heart
• L'alimentation molle a rétréci nos mâchoires : mâcher et réapprendre devient vital

À l'intérieur de ce bit

1. L'habitude sous nos yeux

   You take about 25,000 breaths a day and probably never think about a single one. James Nestor, a journalist, became curious when a breathing class left him feeling unexpectedly well, and he spent years chasing the science behind it.

2. Le nez n'est pas une option

   The nose is a sophisticated organ, not just a hole for air. It filters dust and germs, warms and moistens what you inhale, and produces nitric oxide, a molecule that widens blood vessels and helps your lungs absorb oxygen more effectively.

3. Moins d'air, plus d'oxygène

   It sounds backwards, but breathing more does not mean getting more oxygen. Your blood is usually almost fully loaded with oxygen already.

4. The rhythm of 5 and a half

   Across cultures, Nestor found that prayer chants, mantras, and rosary recitations tend to settle around the same pace: roughly 5 to 6 breaths per minute, about 5 and a half seconds in and 5 and a half seconds out. Researchers measuring people at this rate see blood pressure fall, heart rate variability rise, and the body shift toward its rest-and-repair mode.

5. Petites bouches, voies étroites

   Why do so many people snore, need braces, or wake up tired? Nestor traces part of the answer to our jaws.

6. Passez à l'action

   This week, notice whether you breathe through your mouth during the day and gently close it, letting the nose do its job. Try 5 minutes of slow breathing, about 5 and a half seconds in and out, once in the morning and once before bed, and see how your shoulders and pulse respond.
