Share To see what all the fuss was about I recently dipped my toe in Oxfordshire’s icy cold waters. Did I like it? Maybe. I’m no stranger to plunging into murky depths (I’ve done a few triathlons and trained in toe-curling conditions) but 5C in a local lake in March was something beyond. There I was, teetering on the edge of the water wearing little but a swimming costume and rash vest, neoprene gloves and booties, yet ‘cold’ didn’t come close to describing it. It felt as if a million little knives were stabbing me all over as it literally took my breath away. I should have checked out king of cold therapy Wim Hof’s breathing techniques (wimhofmethod.com).
