I cold water swim through autumn and winter in a lake and an unheated lido, and my mum and a friend have sent me this news story today. It's incredibly sad, and I feel so, so sorry for her children, family and friends.
Cold water swimming does carry risks, I'm not sure of the temperature of the lake this lady was swimming in, but the lake here has gone from 2.8 to 6.8 from the beginning of winter to now, and 2.8 was enough to take your breath away and would cause you to feel quite ill if you stayed in too long. At 2.8 degrees, 5 minutes is plenty for me swimming in a swimsuit, swim boots, swim gloves & bobble hat, and I'm not sure you could stay in too much longer in a wetsuit to be honest.
I absolutely get why people would think the idea of it is is horrible, but I genuinely feel invigorated, energised and ready for anything after a cold swim, and the friend and I who go together relish that time to ourselves, when you can think about nothing else but your breathing and keeping swimming as the cold water hits you.
