I'm an outdoor swimmer (well, bobber-abouter really)...
It shocks me that there is so little accurate information and a lot of scarey but vague information that leads people to make stupid decisions.
For example, people being told that lakes, quarries and reservoirs in the middle of August after a heatwave of a fortnight, will still be 'barely above freezing' when any muppet knows that this is patently untrue..
Which leads them to think that as its clearly a lie, its safe for them to run about, get roasting hot and then dive in...
And whilst the water is NOT 'barely above freezing' it is of course significantly colder than their body temperature (particularly if they dive below the nice warm surface layer of about 2ft), and so they get a shock and that CAN be enough for them to sink, which can be enough to make them panic and drown very very quickly.
Thats just one example of how dumbing down the information leads people to make stupid decisions - I can think of at least two people who almost certainly would NOT have drowned locally, had they understood to get in slowly, acclimatise, consider that they may well be doing more exercise than they are used to, and not go out of their depth..
People are not used to doing risk assessments for themselves - any time I look at somewhere to swim I am looking at:
Access point - can I get in and out safely
Whats up stream and downstream if its a river,
Where will the current take me - river or sea
Whats the bottom like - steep, shallow, mud, rocks, bits of metal?
What else is in the water - boats, other people, anglers, swans, pike? (they scare me) weeds, sunken branches or bits of fence post.
How cold is it?
How warm is it out of the water
How windy is it?
Probably lots of other things besides, because I was taught to do this, because i know water is dangerous and WHY its dangerous and HOW it is dangerous.
And I have a reasonable idea of my own capabilities in the water - not fab actually so I stick to lakes or slow flowing shallow rivers and nothing with a strong current or difficult access/exit.
I do think that alongside the 'not believing the blatant lies we are told about how dangerous something is' we ALSO seem to have a strange believe that we DONT have to take responsibility for ourselves, someone else will... I have no idea why!
