One way that I read is to alternate between hot water and cold water (maybe half a minute for each) for something like 3-4 times but always end the shower with cold water.

Then there is another way mentioned at Earthclinic (http://www.earthclinic.com/Remedies/showers_questions.html#Question_2028) that says shower in cold water only until body temperature rises (takes about 3 minutes).

So, I would like to know which is better way of doing cold shower?
