In November 2013, I completed the Florida Ironman Triathlon. That seminal accomplishment was preceded by one year of cold showers. That’s right, 365 consecutive days, and then some, of taking only cold showers as part of my training. I revisited this in January 2017 briefly when our hot water heater died and could not be replaced for 5 days.
It is now July 23 and I have not taken a hot shower since January 1. An otherwise normal person might ask a perfectly reasonable question: why? To answer that, I have to go back to a chance comment by my son-in-law in 2012 as I was wrestling with the decision to attempt an Ironman. David mentioned that some athletes use cold showers to help them train. There are many benefits to a cold shower. They can help sore muscles recover faster. They can improve circulation to muscles and heart by constricting blood vessels in the skin. They can stimulate a rush of feel-good hormones and neurotransmitters in the body, and provide a host of other benefits as well.
