Understanding and Preventing Shallow Water Blackout in Swimming Pools
Published: Thu, 05/15/25
Hello friend,
Since May is Drowning Prevention Month, I’m dedicating another newsletter to this important topic.
As summer approaches and pool days become part of our routine, I want to talk about something that isn’t often discussed but is so important for every parent and swimmer to understand: shallow water
blackout.
It’s a topic close to my heart because it’s both preventable and often misunderstood.
What Is Shallow Water Blackout?
Shallow water blackout happens when a swimmer loses consciousness underwater,
typically after holding their breath for too long.
Unlike other emergencies, it’s silent and can occur even in experienced swimmers.
The main cause is a dangerous drop in oxygen levels after prolonged breath-holding or hyperventilating before swimming.
How to Prevent Shallow Water Blackout
Never practice prolonged breath-holding. Teach your kids that breath-holding contests, even in
shallow water, can be risky.
Supervise all swimmers closely. Even strong swimmers need eyes on them. Remain alert and avoid distractions.
Educate about the risks. Talk to your children about why they should avoid hyperventilating or challenging friends to hold their breath underwater.
Encourage regular breaks. Make sure everyone takes breaks from swimming to avoid fatigue and maintain
awareness.
Building Water Confidence Safely
Understanding water safety isn’t just about avoiding danger, it’s about building lifelong confidence and skills.
