Our body needs air to survive. Breathing in brings oxygen into our lungs, while breathing out rids our body of carbon dioxide. With this book, guide your readers through the very necessary biological system their body goes through every second of every day. This nonfiction book is paired with the fiction book, A Walk in the Mountains, for connecting across texts and comprehension through connection strategies.

A New York Times Bestseller A Washington Post Notable Nonfiction Book of 2020 Named a Best Book of 2020 by NPR “A fascinating scientific, cultural, spiritual and evolutionary history of the way humans breathe—and how we’ve all been doing it wrong for a long, long time.” —Elizabeth Gilbert, author of Big Magic and Eat Pray Love No matter what you eat, how much you exercise, how skinny or young or wise you are, none of it matters if you’re not breathing properly. There is nothing more essential to our health and well-being than breathing: take air in, let it out, repeat twenty-five thousand times a day. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo and teams up with pulmonary tinkerers to scientifically test long-held beliefs about how we breathe. Modern research is showing us that making even slight adjustments to the way we inhale and exhale can jump-start athletic performance; rejuvenate internal organs; halt snoring, asthma, and autoimmune disease; and even straighten scoliotic spines. None of this should be possible, and yet it is. Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head. You will never breathe the same again.

The Guardian's Best Science Book of 2017: the fascinating science and history of the air we breathe. It's invisible. It's ever-present. Without it, you would die in minutes. And it has an epic story to tell. In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it. With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation. Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

"[A] glorious, glittery saga of friendship and loss... I read The Air You Breathe in two nights. (One might say I inhaled it.)." --NPR "Echoes of Elena Ferrante resound in this sumptuous saga."--O, The Oprah Magazine "Enveloping...Peebles understands the shifting currents of female friendship, and she writes so vividly about samba that you close the book certain its heroine's voices must exist beyond the page." -People The story of an intense female friendship fueled by affection, envy and pride--and each woman's fear that she would be nothing without the other. Some friendships, like romance, have the feeling of fate. Skinny, nine-year-old orphaned Dores is working in the kitchen of a sugar plantation in 1930s Brazil when in walks a girl who changes everything. Graça, the spoiled daughter of a wealthy sugar baron, is clever, well fed, pretty, and thrillingly ill behaved. Born to wildly different worlds, Dores and Graça quickly bond over shared mischief, and then, on a deeper level, over music. One has a voice like a songbird; the other feels melodies in her soul and composes lyrics to match. Music will become their shared passion, the source of their partnership and their rivalry, and for each, the only way out of the life to which each was born. But only one of the two is destined to be a star. Their intimate, volatile bond will determine each of their fortunes--and haunt their memories. Traveling from Brazil's inland sugar plantations to the rowdy streets of Rio de Janeiro's famous Lapa neighborhood, from Los Angeles during the Golden Age of Hollywood back to the irresistible drumbeat of home, The Air You Breathe unfurls a moving portrait of a lifelong friendship--its unparalleled rewards and lasting losses--and considers what we owe to the relationships that shape our lives.

The book covers the three largest sources of particulate matter pollution in five chapters. These sources constitute three of the top ten public health problems in the world today and far outstrip any other environmental health threats in terms of health impact. The book begins with indoor solid fuel combustion for cooking in lower income countries and tells the story of how this problem was identified and recent efforts to eliminate it. The book next looks at tobacco smoking and second hand smoke, again reviewing the history of how these problems were identified scientifically and the fierce industry push back against the science. The last two chapters cover ambient particulate matter in the outdoor air. They address fine and ultrafine particles, describing the pioneering work on fine PM, the subsequent industry attacks on the scientists and then the emerging interest and concern about ultrafine particles, an area of research in which the author has participated. This book is geared towards non-scientists, including high school and college students.

Discover the Christian roots of the values we prize in western society. Is Christianity history? Or is Christian history the deepest explanation of the modern world? Today in the west, many consider the church to be dead or dying. Christianity is seen as outdated, bigoted and responsible for many of society’s problems. This leaves many believers embarrassed about their faith and many outsiders wary of religion. But what if the Christian message is not the enemy of our modern Western values, but the very thing that makes sense of them? In this fascinating book, Glen Scrivener takes readers on a journey to discover how the teachings of Jesus not only turned the ancient world upside down, but continue to underpin the way we think of life, worth, and meaning. Far from being a relic from the past, the distinctive ideas of Christianity, such as freedom, kindness, progress and equality, are a crucial part of the air that we breathe. As author Glen Scrivener says in his introduction: “The extraordinary impact of Christianity is seen in the fact that we don’t notice it". This is a book for both believers and sceptics-giving Christians confidence to be open about their faith and showing non-Christians the ways in which the message of Jesus makes sense of their most cherished beliefs. Whoever you are, you’ll gain a deeper appreciation for the values you hold dear as you discover the power and profundity of Jesus and his revolution.
