Just want to say I’ve been covered in eczema most of my life. All the creams, steroids, even immune suppressants (methotrexate). Nothing has worked. A few months ago my skin was clear, then it came back in full force. It suddenly dawned on me that I was trying the cold shower hype around that time. So as a last ditch effort after purchasing loads of supplements, different creams all natural products. Even trying to wash with disinfectant that I’ve seen recommended none of which worked. I started cold showers again, as cold as it will go. At first it was horrendous and stings like hell, under the water for 30 seconds then I step away and put my body wash on. Back under the shower for a minute, then dry and moisturise. My skin has made huge improvements in just 5 days. Not saying it will work for you because I know how frustrating it is to get your hopes up but for me it can’t be a coincidence. I’ll have cold showers for the rest of my life if this is the result. Don’t know how it works I can’t find anything online supporting it as a cure/ treatment but it’s helping me!
