As the benefits I have mentioned before, I have not noticed too much of the benefits that many articles promised.
Which is:
I have completed a full year of showering in the cold, throughout winter and when I was traveling overseas in Hong Kong and Japan.
What I have noticed is from showering only with cold water is that the time it takes to shower is a lot quicker since I am not waiting for the shower to warm up and I do not shower for extended periods of time. What I can vouch for is that my skin and hair is a lot healthier since I rarely use lotion or any skin products, I noticed that have not had any problems with dry or itchy skin. During the winter months, that tap water was really cold and I measured it to be 55 F (12.8 C) resulting in a redness to my skin similar to taking a really hot shower.
Pros:
Con:
Now the decision is up to you if you want to try this. I probably would continue showering this way until I get sick and when I do I promised to let you guys know!
