Immerse yourself in the wonderful world of wild swimming - you won't regret it.'DR RANGAN CHATTERJEE. Each of us is just a drop. But together we create ripples. Wild swimming isn't just an activity.

It has been a movement, a wave that has surged in popularity across Britain, rippling out and spreading joy. And at the centre of it all are the groups and communities that gather at the water's edge... to dip together, scream together, laugh together, and share stories and support.

From menopausal mermaids to student dippers, male mental health groups to Wim Hof enthusiasts, addiction recovery communities to skinny dippers, The Ripple Effect dives into what makes these groups tick and why so many people say it's not just about the water but the marvellous pods of people they find themselves swimming with.
