Cold Therapy: The Promise and Perils of Ice, Cold Exposure, and Metabolic Health (The Promise & Perils Series — Book 4) Cold exposure is everywhere—ice baths, cold plunges, cryotherapy.

But does it actually improve metabolism, fat loss, and recovery… or is most of it just hype?

In Cold Therapy, Alex Apple cuts through the noise with a clear, evidence-informed look at one of today's most talked-about biohacking trends.

This audiobook explores how cold exposure affects the body—from metabolism and fat loss to recovery, inflammation, and performance. It explains brown fat activation and thermogenesis, how the nervous system and hormones respond to cold stress, and the role of mental resilience and adaptation.

More importantly, it examines where the claims begin to fall apart.

You'll learn what cold exposure actually does—versus what's exaggerated. You'll understand the real impact on calorie burn, when cold can support recovery and when it may interfere with it, and the most common mistakes people make when using ice baths or cold plunges.

The book also outlines practical, safe approaches for both beginners and more experienced users, while highlighting when cold exposure may not be appropriate.

Rather than offering rigid protocols or one-size-fits-all advice, this audiobook focuses on clarity and context. Most books tell you what to do. This one helps you understand what's proven, what's uncertain, and what's often misunderstood—so you can make informed decisions instead of blindly following trends.

Cold Therapy is part of the Promise & Perils series, a science-based collection exploring modern health, performance, and longevity through an evidence-aware lens.

Whether you're an athlete, a biohacker, or simply curious about cold exposure, this audiobook offers a balanced, grounded perspective on what actually matters—and what doesn't.
