I have taken a cold shower in the morning for over ten years, and can attest that I suffer less cold and flu symptoms than other workers in my office. In fact when the flu virus strikes Sydney each winter, I am normally the only one unaffected. When I am in the shower I also do some stretching. I hold onto the top of the shower screen and stretch my spine, to release stress. Which is great, because I have a stressful job. For years I have told others my theory about the benefits of cold showers, but am usually met with derision. So I am glad I found on this website a community of like-minded enthusiasts. I had my blood tested and my white cell count is three times higher than average. So I am sure that a wider scientific study would verify the health benefits of the cold shower. Gerald.
I decided to finish every normal 'hot shower' with a blast of totally cold water, after reading a book by an old healer by the name of Jethro Kloss. Anyway, I am a bad asthmatic, and used to get sick around 6 times per year. When I got sick it really affected my chest, with huge amounts of mucous, and real bad asthma.
Now I rarely get sick (it boosts the immune system as well as circulation), and if I do it's usually just a mildly sore throat. I wish I could better explain the massive difference this has made. Even if you feel sickness coming on, a cold shower will often stop it in its tracks.
