Answer by Tbones1119. Confidence votes 69. The average person can hold there breath for about 30 to 40 seconds, not that long uh. But some people mainly free divers who have been diving for a long period of time their lungs and heart have expanded and got used to holding their breath for longer times.he average time is around 30 - 40 seconds, but many people can hold it for longer and shorter amounts of time.
The current record for pure breath-holding is 22 minutes, set by Stig Severinson in May of last year. And you probably remember David Blaine sitting in a bubble for 17 minutes 4 seconds. That is far longer than the 30 or 40 seconds most of us can hold for, to a really phenomenal degree.yclist Miguel Indurain has massive lungs for a non-diver (8 liters), and they were reportedly large enough to displace his stomach, which gave him a trademark paunch. Chances are you won't need to hold your breath for 20 minutes in your lifetime, or even 5 minutes.
