How long can you survive in hot water?
Generally, a person can survive in 41-degree F (5-degree C) water for 10, 15 or 20 minutes before the muscles get weak, you lose coordination and strength, which happens because the blood moves away from the extremities and toward the center, or core, of the body.
What temperature of hot water will kill you?

How hot does water need to be to kill you?
Although, some bacterial spores not typically associated with water borne disease are capable of surviving boiling conditions (e.g. clostridium and bacillus spores), research shows that water borne pathogens are inactivated or killed at temperatures below boiling (212°F or 100°C).
How long can you stay in 70 degree water?
The average surface water temperatures in inland lakes in summertime is about 60 to 70 F. At those temperatures, a person can lose the ability to make coordinated hand and finger movements in as little as 40 minutes, can become exhausted in as little as 2 hours, and can sustain swimming for less than 2 hours.
