Between 30-180 seconds of oxygen deprivation, you may lose consciousness.
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.
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.
If your breathing has become labored and difficult for no obvious reason, it may be the sign of a more serious medical problem. If chest pain or pressure, fainting or nausea accompanies shortness of breath, you should treat it as a medical emergency.
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.
On 27 March 2021, Croatia's Budimir Šobat achieved the world record for breath-holding underwater, with a time of 24 minutes and 37 seconds. However, he breathed pure oxygen before immersion.
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.
In particular, the temporal lobe (at the temples) is sensitive to oxygen deficiency which is also where the memory is situated. A lack of oxygen from three to nine minutes can result in irreversible brain damage! In case of a cardiac arrest a CPR (Cardiopulmonary resuscitation) is best started within two minutes.
Contrary to previous notions that brain cells die within 5 to 10 minutes, evidence now suggests that if left alone, the cells of the brain die slowly over a period of many hours, even days after the heart stops and a person dies.
Risk of Brain Damage after Cardiac Arrest
If CPR is initiated within: 0–4 minutes: unlikely to develop brain damage. 4–6 minutes: possibility of brain damage. 6–10 minutes: high probability of brain damage.
Your doctor will go over your medical history and perform a physical exam. If there is concern your fainting episode could be a predictor of something for more serious, such as a heart condition, you will likely receive a series of tests. Electrocardiogram (EKG or ECG) - records the electrical activity of your heart.
Call or tell someone to call 911 or the local emergency number. Check the person's airway, breathing, and pulse frequently. If necessary, begin CPR. If the person is breathing and lying on their back, and you do not think there is a spinal injury, carefully roll the person toward you onto their side.
Overview. Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when standing after sitting or lying down. Orthostatic hypotension can cause dizziness or lightheadedness and possibly fainting. Orthostatic hypotension can be mild.
With this, the actress has beaten a record held by Tom Cruise in 'Mission: Impossible—Rogue Nation'. Cruise, who is known for doing shocking stunts, held the record for holding his breath for six minutes.

Contrary to what many people believe, entering the Guinness Book of World Records does not have any type of economic compensation. Therefore, you will not receive a single euro, pound or dollar for breaking a record.
Two friends have broken the Guinness World Record for the longest continuous hug, raising over £7,000 for leading mental health charity Mind. Joe Snape and Will Jarvis broke the record for the longest recorded hug, standing at 36 hours, 36 minutes, and 36 seconds between Saturday 23rd and Sunday 24th June 2018.
On april 30, 2008, David Blaine appeared on the Oprah Winfrey show to attempt to break the Guinness World Record for breath holding. He succeeded in holding his breath for 17 minutes 4 seconds, setting a new world record for oxygen assisted static apnea.
These symptoms often occur as a result of stress and panic attacks. Other possible causes include asthma and cardiovascular disease. People should speak with a healthcare professional if they experience frequent or unexpected episodes of dizziness and shortness of breath.
“Technically, shallow breathing means shorter inhaling and exhaling than normal breathing but with an equal cadence. While in shortness of breath, inhalation is usually much shorter than exhalation,” Dr. Gupta says.
Coronary artery disease causes most cases (80%) of sudden cardiac death. In people who are younger, congenital (since birth) heart defects or genetic abnormalities in their heart's electrical system are often the cause. In people age 35 and older, the cause is more often related to coronary artery disease.
