James Nestor, author of Breath: The New Science of a Lost Art, explains how simple breathing adjustments can improve health, longevity, and performance.
Five Ways to Improve Your Breathing
1. Stop Breathing Through Your Mouth 🛑👄
📌 Timestamp: 00:00:23
- Mouth breathing is inefficient but keeps you alive.
- Nose breathing is far superior because it:
- Filters out toxins, viruses, and bacteria.
- Heats, pressurizes, and moisturizes air.
- Increases oxygen absorption by 20%.
- Mouth breathing’s negative effects:
- Causes hyperventilation and stress.
- Leads to facial structure changes.
- Increases risk of periodontal disease and anxiety.
- Why mammals breathe through their noses:
- 5,400 other mammal species are not habitual mouth breathers.
- Dogs pant for heat regulation, but no mammal breathes through their mouth by default.
- Nose breathing should be our standard mode.
2. Improve Your Lung Capacity 🫁💨
📌 Timestamp: 00:04:59
- Lung capacity is the #1 predictor of longevity—more than genetics or diet.
- After age 35, lung capacity naturally declines, but this can be prevented.
- How to improve lung capacity:
- Proper posture to allow full lung expansion.
- Slow, controlled breathing rather than short, shallow breaths.
- Exercise (even moderate activity) and yoga help maintain lung function.
- Ancient Yoga’s role:
- Originally, yoga was a breathing practice, not just movement-based exercise.
- Controlled breathwork expands lung capacity and optimizes oxygen intake.
3. Slow Down Your Breathing 🧘♂️
📌 Timestamp: 00:06:52
- Slow inhales and longer exhales activate the parasympathetic nervous system, inducing relaxation.
- Nervous system control through breath:
- 80% of signals between the brain and body come from the body.
- If you breathe rapidly and shallowly, your body signals stress.
- Slow breathing sends signals of calmness, reducing stress hormones and inflammation.
- Breathing technique:
- Inhale for 3 seconds, exhale for 6–8 seconds.
- Benefits: Lowers heart rate, reduces blood pressure, and increases CO₂ tolerance.
- Extending exhales further relaxes the body:
- Enhances oxygen efficiency in the bloodstream.
- Improves focus and mental clarity.
4. Hold Your Breath (Properly) ⏳😮💨
📌 Timestamp: 00:09:20
- Bad breath-holding habits:
- Many people hold their breath unconsciously due to stress (e.g., while reading emails).
- This leads to a cycle of shallow breathing and stress buildup.
- Intentional breath-holding is beneficial because:
- It increases CO₂ tolerance, which improves breathing efficiency.
- Helps in athletic performance and focus.
- Surprising fact:
- Oxygen levels don’t drop quickly when holding breath—it’s CO₂ buildup that triggers the urge to breathe.
- Training breath-holding teaches the body to use oxygen more effectively.
- Useful applications:
- Deep diving, meditation, sports performance, and relaxation techniques.
5. Breathing Adjustments Have a Transformative Effect 💡🌬
📌 Timestamp: 00:10:58
- Small breathing changes throughout the day can significantly improve health, sleep, and focus.
- Breathing is simple yet powerful—science shows even small tweaks can make a big difference.
- Key takeaways:
- Breathing correctly isn’t complex but is often overlooked.
- It’s backed by scientific research and real-life experiences.
- Those who control their breathing can improve their health naturally.
