Why Divers use HELIUM on Deep Dives | SCUBA SCIENCE 22

Why do deep divers use helium instead of air? In this SCUBA SCIENCE episode, we explore the physics and physiology behind helium diving, trimix, heliox, and other deep diving gas mixtures. As divers descend deeper underwater, increased pressure changes how breathing gases affect the body. Nitrogen narcosis can impair judgment, oxygen can become toxic, and dense gas makes breathing more difficult. Helium helps solve many of these problems, which is why it has become a cornerstone of modern technical diving. ⌚ Chapters in this video: 00:00 Introduction 00:36 The Basics 02:42 Nitrogen Narcosis 04:15 Oxygen Toxicity 05:44 Why Helium? 08:01 High Pressure Nervous Syndrome HPNS 09:19 Trimix and Heliox 10:16 Disadvantages of Helium 11:50 Conclusion Whether you're interested in: Technical diving Deep wreck diving Cave diving Mine diving Diving physiology SCUBA science and training this episode provides a clear, evidence-based explanation of why helium has become the preferred gas for deep exploration.
