The REAL Secrets to Improve AIR CONSUMPTION Explained | SCUBA SCIENCE 21

Many divers assume that depth is the main reason they burn through their tank. But the reality is more complex. In this episode of SCUBA SCIENCE, we break down the real factors that determine your air consumption underwater. This episode is supported by ADEX Ocean Week in Singapore. Join me April 10-12 to the best SCUBA diving trade show in the Asia Pacific region.

Understanding these factors doesn’t just make you a better diver — it also helps you increase safety, extend bottom time, and improve overall dive performance. In this video you'll learn: • Why depth alone doesn’t explain air consumption • How workload and drag dramatically increase breathing rate • The surprising role stress and the nervous system play underwater • Why CO₂ — not oxygen — drives your breathing • Practical techniques to improve your SAC/RMV and conserve gas ⌚ These are the Chapters: 00:00 Introduction 01:43 ADEX Ocean Festival Singapore 02:17 What "Air Consumption" Really Means 03:22 Workload 04:31 Stress 05:44 Good Buoyancy Control 06:58 Trim and Drag 07:48 Breathing Technique 09:05 Weighting 10:15 Conclusion Whether you're a new diver trying to improve your air consumption or an experienced diver interested in the physics and physiology of breathing underwater, this episode breaks it down in a clear and practical way.
