Without breathing: 22 minutes. The longest any human being ever went without breathing took place in 2012, when Danish freediver Stig Severinsen held his breath underwater for 22 minutes. Without oxygen, the human brain will die after about four minutes.
Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later.
Navy SEALs can hold their breath underwater for two to three minutes or more. Breath-holding drills are typically used to condition a swimmer or diver and to build confidence when going through high-surf conditions at night, said Brandon Webb, a former Navy SEAL and best-selling author of the book “Among Heroes.”
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. Holding your breath can cause high blood pressure, brain damage, or even fainting.
While filming the James Cameron project, Winslet famously held her breath underwater for seven minutes and 47 seconds. The moment officially broke Cruise's previous record after he lasted for six minutes while shooting Mission: Impossible — Rogue Nation in 2015.
Breath-holding is usually harmless
usually last for less than 1 minute (if the child faints, they'll usually regain consciousness within 1 or 2 minutes)
Chris Hemsworth might play a superhero on-screen, but the Thor actor has proven himself to be somewhat superhuman in real life too. The Australian actor left fans stunned with his attempt at holding his breath underwater – achieving a very impressive 200 minutes in total.
The average person can hold their breath for 30–90 seconds. This time can increase or decrease due to various factors, such as smoking, underlying medical conditions, or breath training. The length of time a person can hold their breath voluntarily typically ranges from 30 to 90 seconds .
Those with breath holding time of 25 seconds and above are considered to be safe. One must take care to not try too hard and get exhausted in the process.
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.
David Goggins is the toughest man alive. There's no doubt about it. Goggins is the only member of the US Armed Forces to complete SEAL training, US Army Ranger School, and Air Force Tactical Air Controller training.
The longest ever recorded dive by a whale was made by a Cuvier's beaked whale. It lasted 222 minutes and broke the record for diving mammals. Other whales can also hold their breath for a very long time. A sperm whale can spend around 90 minutes hunting underwater before it has to come back to the surface to breathe.
The world record for a non-oxygen-assisted breath hold is 11:35 minutes* by Stéphane Mifsud. For women it is 9:02 minutes, held by Natalia Molchanova. These are people who have trained for many years, and are the top professional apneists (apnea means temporarily stopped breathing).
Severe oxygen deprivation can cause life-threatening problems including coma and seizures. After 10 minutes without oxygen , brain death occurs. Brain death means there is no brain activity. A person needs life support measures like a mechanical ventilator to help them breathe and stay alive.
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.
If CPR is not performed within two to three minutes of cardiac arrest, brain injury can occur and becomes worse the longer it takes for blood flow to be restored. After nine minutes, brain damage is extremely likely.
How long you can safely hold your breath depends on a number of factors including age, body mass and overall health. Most people can hold their breath comfortably for about 1-2 minutes. Trying to hold your breath for much longer than this, especially under water, may be dangerous.
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.
How do you know your lungs are healthy? If your breathing is natural, comes easily and not forced, is steady and makes you feel good, or is so regular you do not notice it at all, your lungs are most likely healthy.
You should only hold your breath for as long as it feels comfortable. The longer you hold your breath, the more carbon dioxide builds up inside your body; this can result in feelings of discomfort, and might cause you to pass out. If you experience any discomfort while holding your breath, you should exhale.
The record has come a long way since the first documented attempt by Robert Foster (USA), who voluntarily held his breath for 13 min 42.5 sec under 3.05 m (10 ft) of water in a swimming pool in San Rafael, California, on 15 March 1959.
Illusionist and stunt performer Harry Houdini was famously capable of holding his breath for over three minutes. But today, competitive breath-hold divers can squeeze ten, fifteen, even twenty minutes out of a single lungful of air.
