When you look into this there are a number of different approaches to being under water for extended periods of time.
Professionals train for years and can hod their breath for exended periods of time (beyond the capacity of untrained people). he current record for underwater survival is almost 18 minutes after breathing just oxygen for half an hour and slightly over halfthis time or just breathing air.
There are deep free divers who swim down almost a hundred meters on a lungful of air, this takes several minutes(up to 8 minutes) down and up. The biggest danger is having the blood CO2 build up so that you pass out and don't bother to come up.
And finally there is the deep diving reflex. When a human is submerged into cold water the body responds by closing down alot of systems that use oxygen. This extends the period of survival. The reflex is strongest in young children (0 to 4 years) who have been rescued after several minutes (up to forty) , nearly frozen, under water.
