The average person can hold their breath for 30 to 90 seconds, a seemingly simple action that triggers a complex physiological response within the body. This guide dives deep into exactly what is hold your breath, examining the science behind it, the potential health benefits of controlled practice, and the significant dangers of pushing your limits.

The human brain, though only about 2% of the body's weight, consumes roughly 20% of its oxygen supply, making it exceptionally vulnerable to deprivation. While the average person can only hold their breath for a minute or two, understanding **what is the longest time you can survive without oxygen** reveals a complex interplay of physiology, extreme training, and environmental conditions that can push human limits to astonishing, and sometimes perilous, extremes.
