Sleep Health Science

Dung beetles might sound dirty, but the ancient Egyptians believed their god took the form of a dung beetle to roll the morning sun across the sky every day. In this episode, we roll with dung beetles around the world as they push their precious dung—often in balls many times larger than they are—over Florida pastures, Armenian highlands, and the vast South African savanna.

Brown bears lead deeply cyclical lives. They need to gain sometimes hundreds of pounds during the warmer months to prepare for winter hibernation, a lifestyle that brings them into frequent contact with many other species’ cycles. In this episode, we meander through the Alaska peninsula with a bear and her cubs as she teaches them to hunt salmon at the falls, dig for clams along the coastal mudflats, and use the regional rubbing tree.

Sloths are the slowest mammals on earth. They can hardly see. They live in rainforests among jaguars, pumas, and countless other predators. Yet they survive. And they do it by being so incredibly slow, and living a life covered in algae. In this episode, we hang with a sloth in the jungle of Costa Rica as he spends a month digesting one single leaf, and we see the symbiosis and collaboration that surrounds him.

Fennec foxes’ ears can be up to half as long as their bodies. They use them to track movement across the Sahara Desert, including under the sand. In this episode, we follow a fox as he meanders home to his family through the sand dunes as they slowly shift with the wind.

Humpback whales are among the most intelligent animals on Earth. Some scientists believe they might even surpass humans in self-awareness, empathy, and communication skills. In this episode, we swim with a whale as he teams up with other humpbacks to use bubbles to catch fish, rescues a sea lion, and puts his own spin on melodies sung by whales across the Pacific Ocean. This is the world in its natural state, defined by seasons, routines, and cycles. By the time this whale is ready to close one eye and go to sleep, you will be too.

Dogs are a familiar and comforting part of many of our lives. In this episode, we take a walk with a pet xoloitzcuintli, or Mexican hairless dog, as he greets his blocks by smell. Along the way, we learn the backstory of squirrels in U.S. cities and observe the very smart and clean neighborhood raccoon.

Platypuses are mammals unlike any other on earth. They lay eggs, ooze milk through their skin, and can sense electricity. In this episode, we travel with a platypus as he moves through his nightly routine on the island of Tasmania. He uses electroreceptors to hunt underwater and does a synchronized swimming courtship ritual with his mate, who then digs a burrow 40 feet deep into the riverbank to nest.

The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

Elephants are the largest land animals in the world. They are also intensely social and have advanced long-term memories. In this episode, a parade of Asian elephants makes its way through the Sri Lankan forest to a lake for drinks and mud baths, stopping periodically for group naps. The female leading the parade uses infrasonic rumbles—inaudible to humans, but traveling as far as two miles along the surface of the Earth as seismic waves—to invite friends and family around the forest to join her at the reservoir.

For modern science, the transitional states of consciousness lie at the forefront of research in many fields. For a Buddhist practitioner, these same states present crucial opportunities to explore and transform consciousness itself. This book is the account of a historic dialogue between leading Western scientists and the Dalai Lama of Tibet. Revolving around three key moments of consciousness - sleep, dreams, and death - the conversations recorded here are both engrossing and highly listenable.

Crows have long been the subject of folklore, likely because they’re strikingly similar to humans, leading lives rich in personality, intelligence, and relationships. In this episode, we fly the streets of Seattle with a crow as she grooms her mate, delivers what appears to be a gift, and finally commutes miles away from her territory to gather and chat with thousands of other crows before it’s time to roost for the night.

Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in 21st century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking and reproducing - the purpose of sleep remained elusive.

For many people who have trouble sleeping, each night is an anxious odyssey where getting a good night’s sleep feels like a battle to win rather than a basic biologic process. Hello Sleep is a guide for people with insomnia to help them shift their relationship with sleep, so that it stops being a battle and starts being enjoyable and natural again. It is a practical, self-guided tour through evidence-based interventions for chronic insomnia.

While on a research trip in Peru, science journalist Alice Robb became hooked on lucid dreaming - the uncanny phenomenon in which a sleeping person can realize that they're dreaming and even control the dreamed experience. Finding these forays both puzzling and exhilarating, Robb dug deeper into the science of dreams at an extremely opportune moment: just as researchers began to understand why dreams exist. They aren't just random events; they have clear purposes. They help us learn and even overcome psychic trauma.

For 200 years, a noble Venetian family has suffered from an inherited disease that strikes their members in middle age, stealing their sleep, eating holes in their brains, and ending their lives in a matter of months. In Papua New Guinea, a primitive tribe is nearly obliterated by a sickness whose chief symptom is uncontrollable laughter. Across Europe, millions of sheep rub their fleeces raw before collapsing. What these strange conditions share is their cause: prions.

Sleep is the hottest of hot topics. Experts queue up to warn us that lack of sleep, or the wrong kind, will bring down a bewildering array of dire consequences. But how do we keep from being overwhelmed by this deluge of data? What if all this knowledge just feeds anxiety and drives sleep even further from our grasp? Heather Darwall-Smith's message is simple: Don't panic! Humans are biologically programmed to sleep - and by interrogating the factors that might impede this innate instinct, we can make changes in our lifestyles and find our way back to good sleep.

The Happy Sleeper shows parents how to avoid and undo cumbersome sleep habits, putting their babies and little kids on track to a full night's sleep. Heather Turgeon and Julie Wright teach parents that babies have an innate capacity to self-soothe, as well as the brain machinery to sleep well. So why do many families struggle at night? Most do what works today, but don't notice when it's no longer needed tomorrow, and then push harder when it becomes a hindrance the day after that.
