How long human stay in water?

Humans can typically hold their breath underwater for about 30 seconds to 2 minutes, depending on individual training and conditioning. However, with proper training, some can extend this to several minutes. In terms of survival, a person can generally survive without air for 3 to 10 minutes, but this varies based on factors like water temperature and individual health. Hypothermia can also limit the time one can stay in water, especially in cold conditions.
