Breath

重要なポイント

• 呼吸法は、食事や運動と同じくらい重要
• 鼻呼吸は空気を整え、酸素の巡りを良くする
• 現代人は吸いすぎ。ゆっくり浅く呼吸すると酸素が届く
• Around 5 to 6 breaths per minute calms the nervous system and steadies the heart
• 柔らかい食事が顎と気道を狭めた。噛む習慣が鍵になる

このbitの内容

1. 見落とされがちな基本習慣

   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. 鼻は呼吸のためにある

   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. 少ない空気で、巡る酸素

   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. 小さな顎と、狭まる気道

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

6. 実践に移す

   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.
