What this swimming skill is
Children and teens love underwater challenges: who can stay down longest, or swim furthest without a breath. They feel harmless, but they are not. Holding the breath too long can make anyone pass out underwater, often with no warning. Taking lots of fast, deep breaths before going under makes this more likely, not less.
This skill is about understanding and choices, not about practising anything underwater. It comes once your child is confident breathing in the strokes, and it stays with them for life.
Why it matters
It can happen to strong swimmers.
Passing out from holding the breath can happen to confident, fit swimmers, often without any warning.
Dares spread fast.
Breath-holding challenges spread among friends and online. Knowing the danger helps your child say no.
It protects them without you.
Your child carries the rule to friends' pools, parties and holidays.
Clear family rules.
When everyone understands why, simple pool rules at home are easier to agree on.
Who it is for
This suits children, teens and adults. For younger children, it stays simple: no breath-holding contests, and come up to breathe whenever you want. Teens often face the most pressure from dares and online challenges, so your instructor talks it through openly with them. If you are an adult, and especially a parent, it helps you set pool rules at home and spot risky games.
Anywhere they swim
The goal
Your child can explain, in their own words, why long breath-holding underwater is dangerous. They stop these games themselves and say no when friends suggest them.
Why it matters
Many risky challenges happen when no instructor is around. Understanding the danger is what keeps your child safe at any pool.

How you can help between lessons
- Agree on a family pool rule together: no breath-holding contests and no long underwater swims.
Common questions
- My child loves seeing how long they can stay underwater. Is that really dangerous?
- Yes, once it becomes a contest or a challenge. Holding the breath too long can make anyone pass out underwater without warning. Short, relaxed underwater play, with breaths in between and an adult watching, is fine.
- What is shallow water blackout?
- It is a name often used when a swimmer passes out underwater after holding the breath too long. Despite the name, it can happen in water of any depth. It often gives no warning, which is why the rule is simple: no breath-holding games.
- Is it safe to take lots of deep breaths before going under?
- No. Breathing fast and deep before going under makes passing out more likely, not less. One normal breath before a short dip is all anyone needs.
- My teen swims on a team and kicks underwater off the wall. Should I worry?
- Underwater kicking off the wall is a normal part of racing. It should stay short and supervised, with rest in between, and never become a contest. If practice includes breath-holding challenges, ask the coach about it.
- How do I talk to a young child about this without scaring them?
- Keep it short and matter of fact: we always come up to breathe when we want to, and we never have underwater contests. Children take their lead from your tone, so calm and firm works best.
