How quickly does hypothermia come on after cold water submersion? At what temperature is hypothermia a higher risk? How quick is recovery from mild hypothermia?
These are just a few of the questions I needed to answer for my book. Fortunately it’s one of those topics that doesn’t really change with time, although the answers do vary based on specific conditions.
I found the answers to my questions and lots of other useful information in these links.
This site is one of many that includes a “how long can a person survive in cold water” table.
Includes more videos and graphs than most of the other sites I found. I sometimes need the visuals to understand new ideas, so this was helpful.
If your water situation occurs in the ocean, this seems a valuable tool.
