Why Caffeine Hurts Your Freediving: The Mammalian Dive Reflex Explained

Get ready to have more confidence in your breath hold after learning about the Mammalian Dive Reflex and why you should seriously consider putting a stop to drinking caffeine on the mornings you freedive. We are doing a deep dive through this video to explain the 5 biggest things that happen to our bodies when our face touches the water. I will also be chugging 20oz of Red Bull and then performing more breath holds to show caffeine's negative impact on our heart rate, but how the MDR can essentially counteract the caffeine once our face touches the water. Hopefully, after watching this video you will seriously start to consider not drinking coffee or caffeine before freediving! Please if you have more questions about the things learned in this video leave a comment below! I love answering any and all questions :) Dive safe and never dive alone!
