Harry Beattie, a recovering drug addict, has taken ice baths for almost 600 days in a row as he attempts to become clean. He credits the experience of the cold water to have a positive impact on his mental health and believes they can be used as a tool for those battling addiction. However, experts warn that they should not replace established treatments such as counselling, medical support, rehabilitation programmes, and peer-support groups. Beatie shares his daily cold water plunges with hundreds of thousands of followers on TikTok and Instagram in the hope of inspiring others. His first ice bath took place on 21 July 2024, and he said it changed his life "dramatically".
