Average breath-hold time by age
The measured resting mean for untrained adults aged 19 to 23 is 29.67 seconds, and most of that sample sat between 18 and 41 seconds. Here is what the studies and the certification pass marks show, and where the measurements stop.
The measured average
The measured average is 29.67 seconds, from a 2024 study of 78 untrained adults aged 19 to 23. The standard deviation was 11.55 seconds, so a normal result in that sample runs from about 18 to 41 seconds. Training and the day both move it: the same people held 26.21 seconds during a handgrip task.
Time your own hold with the average breath hold time by age tool, which scores one attempt against every reference time on this page, or use the plain breath-hold timer.
Practise alone only on dry land, seated or lying somewhere stable. Never hold your breath in a pool, bath, or open water without a trained buddy watching the whole attempt and the recovery.
Breath-hold time by age
Published measurements of resting breath-hold time cluster in one narrow age band. The table below says so rather than filling the gaps.
| Age band | Typical untrained hold | After structured dry training | What the number comes from |
|---|---|---|---|
| Under 19 | No measured sample | No measured sample | The studies cited here recruited adults only |
| 19-23 | 29.67 sec mean, roughly 18-41 sec | 1:30 to 3:30 at certification pass marks | Ethiopian J Health Sci 2024, n=78, SD 11.55; PADI and AIDA standards |
| 24-39 | No measured sample | 1:30 to 3:30 at certification pass marks | Pass marks are published requirements, not survey averages |
| 40-59 | No measured sample | 1:30 to 3:30 at certification pass marks | Pass marks apply at every adult age; no age allowance exists |
| 60+ | No measured sample | 1:30 to 3:30 at certification pass marks | Pass marks apply at every adult age; no age allowance exists |
Certification standards set the same pass marks whatever your age, so the training column does not decline down the table. Nobody has published a resting mean for the older bands, and inventing one would be worse than the blank. Body mass index does have a measurement: mean breath-holding time ran from 44.29 seconds in the normal-weight group down to 32.43 seconds in the obese group in a separate study of healthy adults.
Typical times by level
| Level | Typical breath hold | What the number comes from |
|---|---|---|
| Untrained adult | 30-60 sec | Measured resting means of about 30 sec in young adults |
| Entry-level certification | 90 sec - 2 min | PADI Freediver 1:30; AIDA 2 requires 2:00 |
| Advanced certification | 2:30 - 2:45 | PADI Advanced Freediver 2:30; AIDA 3 requires 2:45 |
| Master certification | 3:30 | PADI Master Freediver and AIDA 4 both require 3:30 |
| Competitive static apnea | 6+ min | Finals-level times in AIDA static competition |
| World record | 11:35 (men) / 9:22 (women) | AIDA-approved static apnea records |
The middle rows are the useful ones. Certification standards are published pass marks, not survey averages, so they show what structured training reliably produces in people who complete a course. The record rows show the outer edge of the discipline and nothing about a normal practice session.
Is a 2 minute breath hold impressive?
It clears the AIDA 2 pass mark of 2:00 and beats the PADI Freediver requirement of 1:30, so it puts you at entry certification standard without a course. Against the untrained mean of 29.67 seconds it is roughly four times the average. It says nothing about how long you could stay down safely, because a static hold on land and a dive are different problems.
Is a 3 minute breath hold good?
Yes, by any published standard short of Master level. Three minutes sits above the AIDA 3 requirement of 2:45 and just under the 3:30 that PADI Master Freediver and AIDA 4 both ask for. Competitive static finals start around six minutes, so this is well trained and nowhere near the sport's edge. A longer hold does not buy you a wider safety margin in water.
Is a 4 minute breath hold good?
Four minutes is past every recreational certification pass mark on this page, including the 3:30 Master requirement. It is still two minutes short of a competitive static final. Reaching it usually means structured table work over months rather than a talent you were born with, and it changes nothing about the rule that in-water holds need a trained buddy.
Is a 7 minute breath hold good?
Seven minutes is competition territory. It is above the 6-plus minutes seen in AIDA static finals and about four and a half minutes short of the 11:35 men's record. Times at this level come from supervised training under a coach. Do not treat the number as a personal target: the risk of a long hold does not scale down because someone else reached it.
Why the untrained number varies so much
A 2024 study in the Ethiopian Journal of Health Sciences measured voluntary breath-holding in 78 healthy untrained young adults aged 19 to 23. The resting mean was 29.67 seconds, with a standard deviation of 11.55 seconds. That spread matters more than the mean: a normal, healthy person in that sample might sit anywhere from roughly 18 to 41 seconds.
The same study measured the same people under different conditions and got different results: 26.21 seconds during an isometric handgrip, 33.08 seconds during a mental arithmetic task.
So the honest version is: your resting number depends on how relaxed you are, what you did in the last ten minutes, and factors you cannot change today. A single attempt is a weak measurement.
What actually rises when people train
Rising carbon dioxide contributes to the urge to breathe during a hold. Oxygen level, lung volume, and respiratory-muscle activity also affect where the hold breaks. Training changes your response to those signals rather than adding air to your lungs.
Research on apnea training and performance is mixed and protocol-specific. Reviews report possible benefits for some outcomes while calling for better-defined protocols and more evidence. No study supports a universal percentage gain or a fixed timeline, so treat any program promising "add two minutes in six weeks" as marketing.
Never hyperventilate before a hold. Over-breathing lowers carbon dioxide and delays the urge to breathe without stopping oxygen from falling, which raises the risk of blackout.
Finding your own number safely
- Sit or lie down on dry land, away from water, with nothing you could fall against.
- Breathe normally for a few minutes. No rapid or repeated deep breaths.
- Hold once, and stop at the first strong urge rather than pushing to a maximum.
- Repeat on three separate days and use the middle value, not the best one.
- Stop immediately if you feel faint, confused, or unwell.
Contractions are not a timer. Their onset, strength, and pattern vary between people and between attempts, and they do not tell you how much oxygen is left.
Once you have a baseline, conservative CO2 tables are a more useful practice than repeated maximum attempts, because they let you train the response to the urge to breathe without making every round a limit test. The full training guide covers the progression.
What this page cannot tell you
A breath-hold time is not a lung test. A short hold does not indicate a problem with your lungs, and a long one is not a clean bill of health. One attempt is a weak measurement, the age table above has measured numbers for a single band, and none of these figures says what is safe for you in water.
If you want to train in water
An app cannot teach or supervise an in-water rescue. Take a certified freediving course and dive with a trained buddy. The freediving schools map lists instruction near you.

A breath-hold accident is blackout: loss of consciousness as oxygen falls. On land people normally start breathing again; in water the airway is submerged. Here is how it happens and which controls actually prevent it.
