Even as far back as 1959, researchers demonstrated in seven untrained volunteers that breathing 100 per cent O2 prior to a breath hold resulted in maximum breath hold durations of six to 14 minutes. So Winslet's seven-minute breath hold with only a few weeks' training is definitely possible.
When adults hold their breath for a long period of time underwater, there is also a risk of passing out. In short, the average healthy person can hold their breath for 3-5 minutes. A person's ability to hold their breath can be increased if the person exercises regularly, is a diver or professional athlete.
How long should a healthy person be able to hold their breath?
However, most people can only safely hold their breath for 1 to 2 minutes. The amount of time you can comfortably and safely hold your breath depends on your specific body and genetics. Do not attempt to hold it for longer than 2 minutes if you are not experienced, especially underwater.
How was Kate Winslet able to hold her breath for 7 minutes?
To be fair, Krack tells us, the actress had some help: She inhaled a gas mixture consisting of 50% oxygen − about 30% more than makes up the air we breathe, according to NASA − which allowed Winslet to hold her breath for more than seven minutes, though she could do 5½ minutes on her own.
An average Navy SEAL can hold their breath for 2-3 minutes during underwater exercises, but with proper training, some can extend it to 5 minutes or more.
Professional breath hold diver Budimir Šobat's world record of 24 minutes and 37 seconds holding his breath underwater. During a breath hold, the level of blood CO2 rises, and the O2 declines. The initial increase in the urge to breathe — let's say 30 seconds into the breath hold — primarily comes from the rising CO2.
For most people, it's safe to hold your breath for a minute or two. Doing so for too much longer can decrease oxygen flow to the brain, causing fainting, seizures and brain damage. In the heart, a lack of oxygen can cause abnormalities of rhythm and affect the pumping action of the heart.
Results: The maximum breath-hold time for inpatients and those outpatients who were heavy smokers or had chronic obstructive pulmonary disease (COPD) or congestive heart failure (CHF) was 18 to 32 seconds (95% confidence interval) with a mean of 25 seconds.
How long can a person hold their breath before brain damage?
Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later. Machines called automated external defibrillators (AEDs) can be found in many public places, and are available for home use.
Healthy persons can also practice the breath-holding exercise. It will help them keep their lungs healthy. Patients can practise once in an hour and gradually try and increase the breath holding time. Those with breath holding time of 25 seconds and above are considered to be safe.
Results - The mean breath holding time among smokers was 34.85 seconds, whereas the mean breath holding time was 46.61 seconds among non smokers. Conclusion - The present study showed that BHT was lower among smokers than non-smokers and the difference was statistically highly significant.
At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable.
Holding the breath until you feel a strong air hunger gives the diaphragm a workout and exposes the body to higher levels of carbon dioxide. It improves tolerance to hypoxia and hypercapnia. You won't get so breathless, your breathing will be slower, and your performance will improve.
Breath-holding spells usually end within 30-60 seconds, when children stop holding their breath and start to cry or scream. In some cases, children hold their breath until they lose consciousness.

Can the average person hold their breath for 5 minutes?
The average person can hold their breath for about 30–90 seconds. However, this time can increase or decrease due to factors like smoking, underlying health conditions, and breath training. The length of time a person can hold their breath voluntarily typically ranges from 30 to 90 seconds .
