Researchers Find Visual Countdowns Improve Breath Holding Capacities

Breath-holding (apnea) training is common for freedivers, surfers, and increasingly, mainstream athletes looking to improve their CO2 tolerance. The urge to breathe is actually triggered by a buildup of CO2, not a lack of oxygen.

The Panic Point

When CO2 builds up, the brain triggers a strong panic response. Pushing past this initial panic point requires immense mental discipline.

The Visual Distraction

Researchers find that having a visual timer running during a breath-hold significantly improves capacity. Watching the timer acts as a cognitive distraction from the rising panic. Furthermore, setting a visual goal (e.g., reaching the 2-minute mark) gives the athlete a concrete reason to fight the urge to breathe just a little bit longer.

Why Liquid Countdown Timer?

The Liquid Countdown Timer provides a mesmerizing focal point during difficult apnea training. Its smooth motion distracts the mind and provides the clear visual goalposts needed to safely push your CO2 tolerance limits.
