How long can the average Navy SEAL hold his breath?
two to three minutesNavy SEALs can hold their breath underwater for two to three minutes or more.

What is the lowest your oxygen level can be before you die?
An oxygen level below 88% can be dangerous for any period of time. An oxygen level below 85% warrants a trip to the hospital. Keep in mind that an oxygen level 80% and lower puts your vital organs in danger, so it is important to keep a blood oxygen level chart handy so you know what levels require immediate treatment.
How long does it take to get brain damage from lack of oxygen?

What happens when your brain doesn’t get enough oxygen?
Brain cells start to die if they go without oxygen for just 3-4 minutes — and that’s exactly what happens during a stroke. With each minute that passes, you lose about 2 million brain cells. The longer you go without oxygen, the greater your chance for brain damage that can’t be undone.
Can the brain repair itself?
Research indicates that in many instances, a brain can heal itself after a stroke. … However, brain cells that are damaged are not beyond repair. They can regenerate. This process of creating new cells is called neurogenesis.
How do you increase oxygen flow to the brain?
3) Take short walks throughout the day. Short walks will increase your circulation and increase oxygen to your brain, whereas while forced walks or runs may be good for you too, they also cause your muscles to absorb much of the oxygen in your system, and that hinders increasing the oxygen being carried to your brain.

At what oxygen level does brain damage occur?
Anything below 86% is considered severe. Cerebral hypoxia refers to oxygen levels in brain tissue, not blood.
