Breath: The New Science of a Lost Art by James Nestor explores how the way we breathe affects every aspect of our health. Nestor combines scientific research, history, and personal experimentation to reveal that modern breathing habits are often inefficient and can contribute to issues like anxiety, asthma, snoring, poor sleep and chronic illness. He investigates ancient and modern breathing practices and shares simple, evidence-based techniques that can improve lung function, reduce stress, increase athletic performance and support overall well-being. By reconnecting with how humans are meant to breathe, Nestor shows that small changes can lead to big improvements in physical and mental health.
