This is wilderness medicine education from the Spencer Fox Eccles School of Medicine at the Univeristy of Utah. It is designed for use in the Advanced Wilderness Life Support (AWLS) program, but anyone who goes into the backcountry should study this material. Log onto: www.wildmedu.org for more information.

Sunscreen technology is evolving rapidly, offering better protection, improved cosmetic feel, and a growing focus on environmental sustainability. In this episode, we explore the latest advances in sun protection, including next-generation UV filters such as Bemotrizinol (Tinosorb S), innovations in engineered zinc oxide, antioxidant-rich plant extracts, and ingredients that enhance water resistance and photostability. We’ll separate fact from marketing, discuss what “reef-safe” really means, and explain how these new technologies are helping outdoor enthusiasts stay better protected during long days in the sun. Whether you’re a hiker, climber, trail runner, or simply enjoy spending time outside, this episode will help you make informed choices about the next generation of sunscreens.

In this episode, our hosts Sophie Emery, Kaylee Stark, Noelle Lordahl, and Kate Persak explore how a nonprofit organization is transforming the lives of girls ages 11–17 through backpacking and other outdoor adventures. More than just learning outdoor skills, these experiences build confidence, leadership, responsibility, resilience, and lifelong friendships. We’ll discuss how spending time in nature supports mental health, encourages personal growth, and helps break down financial and social barriers so more young women can experience the outdoors. Join us as we discover how adventure in the wilderness inspires the next generation of confident, capable leaders.

Rabies remains one of the deadliest infections known to medicine, yet it is almost entirely preventable with prompt treatment. In this episode, Alastair Milne from the medical school in the University of Nicosia in Cyprus, explores how the virus is transmitted, and describes a practical scenario to understand how fatalities from this disease can be avoided.

Cuts and lacerations are among the most common injuries encountered in the backcountry, but in wilderness medicine the greatest threat often isn’t the wound itself—it’s infection. In this episode of the AWLS Wilderness Medicine Podcast, we explore why nearly every wilderness wound should be considered contaminated and why thorough irrigation and cleaning are often far more important than closing the skin. Through real-world wilderness cases, listeners will learn when wounds should be left open, why premature suturing can trap bacteria and lead to serious infections, and how proper wound care can make the difference between an uncomplicated recovery and a medical evacuation. Whether you’re a backpacker, climber, guide, first responder, or wilderness medicine provider, this episode offers practical, evidence-based principles for managing wounds safely when definitive medical care may be hours or days away.

Join mountain medicine expert Dr. Sebastián Donato for a fascinating discussion on the realities of altitude illness on Aconcagua, the highest mountain in Western and Southern Hemispheres. Drawing from recent rescue operations and real patient cases, Dr. Donato explores the recognition, prevention, and treatment of acute mountain sickness (AMS), high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE). Through dramatic stories of climbers who required emergency evacuations, listeners will gain valuable insights into the challenges faced by rescuers and medical teams operating in one of the world’s most demanding high-altitude environments. Recent data from Aconcagua show that altitude illness accounts for the majority of mountain evacuations, with HAPE being the single most common reason climbers require rescue. This podcast is ideal for climbers, wilderness medicine practitioners, guides, and anyone interested in the medical and human challenges of high-altitude mountaineering.

In Part 2 of this fascinating podcast series, Dr. Matt Gunderson explores more about Hantavirus, a rare but potentially deadly infectious disease carried primarily by rodents. Dr. Gunderson also breaks down the biology of Hantavirus, This episode provides more details and cases of one of the world’s most intriguing zoonotic diseases.

Canyoning combines hiking, climbing, rappelling, swimming, and navigating through narrow canyons carved by water, creating one of the most exciting adventure sports in the outdoors. However, the same features that make canyoning thrilling also create significant risks. Participants may face foot entrapment in fast-moving water, where a trapped foot can lead to drowning. Rope-related incidents, including improper rigging, equipment failure, and rappelling errors, can result in serious injury or death. Powerful waterfalls and recirculating pools, often called “hydraulics” or “keepers,” can trap swimmers underwater. Cold water exposure and prolonged immersion can lead to hypothermia, even in warm weather. Wet suits are essential, but have hidden dangers. Flash floods, falling rocks, slippery surfaces, exhaustion, and limited access to emergency rescue further increase the danger. In this fascinating episode, Dr. Benny Chen explores the unique hazards of canyoning and the essential skills, preparation, and decision-making required to safely enjoy this challenging sport.

In Part 1 of this fascinating podcast series, Dr. Matt Gunderson explores the origins and characteristics of Hantavirus, a rare but potentially deadly infectious disease carried primarily by rodents. Listeners will learn how the virus was first identified, where it is commonly found, and how it spreads to humans. Dr. Gunderson also breaks down the biology of Hantavirus, its symptoms, and the environmental conditions that contribute to outbreaks. This episode provides an engaging introduction to one of the world’s most intriguing zoonotic diseases and lays the foundation for future discussions on diagnosis, treatment, and prevention.

In this episode, Dr. Kathy Vidlock shares a compelling real-world wilderness medicine experience involving two runners found on a remote trail, each suffering from different medical emergencies. Through the lens of AWLS (Advanced Wilderness Life Support) protocols, Dr. Vidlock explains how returning to the fundamentals of patient assessment, observation, history-taking, and clinical reasoning allowed her to quickly recognize the underlying problems and begin effective treatment in the field. This practical discussion highlights the importance of mastering basic wilderness medicine principles when advanced tools and diagnostics are unavailable.

In this episode, Matthew McKinnon takes a deep dive into the often-overlooked but potentially fatal condition known as suspension trauma. Commonly associated with climbing, rope access work, and wilderness rescue, suspension trauma can develop rapidly when a person is left hanging motionless in a harness. Matthew breaks down the physiology behind the condition, explaining how restricted blood flow can lead to loss of consciousness and even death if not addressed quickly. He also covers the key warning signs to watch for in the field, practical strategies for prevention—including proper harness use and movement—and step-by-step guidance on safe and effective treatment. Whether you’re a climber, rescuer, outdoor professional, or backcountry enthusiast, this episode provides essential knowledge that could save a life.
