Genuinely curious so wondering if anyone knows the answer. I am 44 and when I was young there was lots of tv ads, talks in school etc warning against the dangers of swimming in lakes, rivers etc. We were told that even if you are a strong swimmer it is dangerous due to pollutants, abandoned bikes/ litter/ random objects in the water.
During lockdown I have been aware of wild swimming becoming more popular and even seen articles on the news etc talking about the benefits and encouraging people to have a go. So why is this? What has changed since the 80s? I am just wondering why this was once seen as being dangerous but is now seen in a much more positive light. Have our lakes and rivers got cleaner or is it less of a problem than we once thought?
