What If You Held Your Breath Like Tom Cruise? How the Body Reacts 😳

Tom Cruise held his breath underwater for about six minutes while filming Mission: Impossible – Rogue Nation (2015). Here’s what prolonged breath-holding does to the body. The dive reflex slows the heart, and spleen contraction can release extra red blood cells. Rising carbon dioxide contributes to the urge to breathe. Oxygen also falls; blackout is a serious risk. The 29-minute record is a different category: Vitomir Maričić held his breath for 29 minutes 3 seconds in June 2025 after breathing pure oxygen first. Do not attempt prolonged underwater breath-holding. It can cause blackout and drowning. This explains a trained film stunt and is not a challenge or training guide.
