Advanced Wilderness Life Support (AWLS)

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.
