Cold Showers, Tested

On nickwinter.net

A few months ago, I set out to test cold showers. Here's what I wrote for my experimental mission statement:

People are raving about what hormetic opponent process magic silver bullet it is to take cold showers. A little research gave supposed benefits of increasing circulation, mood, immunity, fertility, energy, exercise recovery, fat loss, mental alertness, pain and stress tolerance, cold tolerance, and skin and hair health. They're even supposed to stop depression and hair loss and tumors. I'm going to alternate two weeks of cold showers with two weeks of hot showers for the next two months and see what actually happens.

So excepting two days of each condition when traveling, every day for two months I woke up, did a 10-minute workout, immediately took a 7-minute shower, recorded my energy, mood, and shower discomfort, and took an 8-minute Quantified Mind battery. This wouldn't tell me anything about skin health and tumors, but it would get the main thing: does a cold shower begin one's day more vigorously than a hot shower?

Results

There were no observable differences on any Quantified Mind tests, suggesting that the brain does not care about the water temperature.

Parkour Shoes and Reviews

On Jumping on Entrepreneurship

As parkour has grown in popularity, a lot of companies have created and sold parkour shoes. A lot of people ask me what is the best shoe for parkour, so I’ve put together this guide to the most common shoes people might suggest for parkour. This is by no means an exhaustive list, these are just the most common ones that I have enough experience with to review.

One quick note: I am a big fan of minimalist shoes. There’s a lot of research out there that shows that the more padding and cushioning a shoe has, the MORE damage it does to your feet, knees, and hips. That’s out of the scope of this article though.

Full disclosure: In early 2010 I received some free Ariakes from K-Swiss. This has not influenced my review, but I wanted to be transparent.

K-Swiss Ariake [caption id="" align="alignleft" width="150" caption="K-Swiss Ariake Parkour Shoe"][/caption]Price: Around $100

Description: This was the first shoe created and marketed specifically for Parkour. They’re made by K-Swiss. They sent a lot of free pairs out to traceurs a few years ago to help spread the word about being a Parkour shoe. Many people wearing Ariakes got theirs for free, either directly from K-Swiss or from someone who got them from K-Swiss. They also come in lots of different (and crazy) colors, which can be a pro or a con depending on your preference. :)
