I have been taking cold showers every day now for almost three months, and I recently got the results of my latest blood and urine lab tests from my doctor. Blood sugar and cholesterol were markedly lower than the tests showed just prior to starting the cold shower regimen, with no appreciable changes in diet or physical exercise. My blood pressure was lower, and my pulse rate at rest has decreased from 72 to 54, which I find amazing. I am not in "great" shape physically, and I can only attribute these changes to the cold showers. This might actually be the 'fountain of youth'.
