The Science of Freediving: Hold Your Breath and Extend your Lifespan

You probably already know that I’m an exercise physiologist—and I’m currently pursuing a master’s degree in applied physiology with a concentration in nutrition for health and human performance—but I’m also a freediver and a spearfisherman. Anybody can freedive but I help people take it to the next level by biohacking their lifestyle.

Have a pen and paper ready because, in this episode, I dive deep (pun intended) into the physiology of elite-level freediving. From breathwork to training, I break down a bunch of techniques so that you can dive deeper and hold your breath longer. I also dish out tips on diving gear and nutritional supplements so stay tuned until the end!

Episode Highlights:

• 00:58 - Why I freedive
• 05:50 - Cryotherapy or cold exposure therapy to find calmness
• 07:02 - The benefits of diaphragmatic, nasal, and box breathing
• 10:15 - “The best training for any kind of sport is going to be that which closely mimics the sport itself.”
• 12:12 - VO₂ max = cardiac output * A-VO₂ difference
• 15:12 - Why high-level divers do HIIT and blood flow restriction training
• 16:48 - How to estimate your maximum heart rate
• 17:18 - How to increase your oxygen-carrying capacity
• 19:21 - On carbon fiber fins and low-volume masks
• 22:00 - Divers would benefit from more BCAAs, electrolytes and carbs
