As I sit here shivering, I can’t help but recall a line from one of my favorite movies, “The Whole Ten Yards.” After a fight with his wife, Oz (Matthew Perry) states that if he doesn’t change his behavior, he will be taking “cold showers for the rest of his life.”
Oddly enough, that might not be so bad…
Only a few a days ago, I purchased a book that I have been looking forward to coming out for months, The 4-Hour Body, by Tim Ferris. Ferris, like myself, takes a great interest in a number of things, including physical health. Moreover, he is just an interesting guy. You should check out his blog at www.fourhourworkweek.com. This book chronicles his last ten years of unconventional experiments he has conducted on himself (after his bestseller “The 4-hour workweek cashed in, he has the luxury of some pretty expensive methods, but his results are just the same). He is a literal human guinea pig. His book has a number of highly fascinating sections – How to give a woman a 15 minute orgasm, how to drop 20 pounds in 30 days (by eating paleo…what a shocker), how to run 50 km in only 4 weeks, how to triple your testosterone etc… One chapter that particularly caught my eye was his discussion of the effects of Ice baths/showers. His studies’ state:
1. (The evidence is rather scientific, but a scientific explanation is not needed for the overall point) Ice Showers recruit necessary cell components (namely, GLUT-4) to the surface of the cell increasing lean muscle gain
2. Even at short durations, cold exposure could increase adiponectin levels and glucose uptake by muscle tissue.
3. In the absence of shivering (short term exposure), there is still a substantial increase in “thermogenesis” increasing fat-burning for heat.
4. Cold Water exposure increases immunity.. He states specifically, “acute cold water exposure has immunostimualting effects, and preheating with physical exercise or a warm shower can enhance this response.”
5. Cold Showers are effective treatment of depression.

In thinking about this from an evolutionary standpoint, it makes sense. There were undoubtedly times when humans had to endure some harsh winters without much food yet required energy – thus, the fat-burning evidence. So, by placing ourselves in a similar situation – albeit less intense – logically should benefit our health.
That being said, I have tinkered around with cold showers for about a year and I thought there was something to it, but I never stuck with the practice – until this week. Simply put, it has been an amazing experience. Thus far, after 5 days, I have gone from a 32.5 waist to 31.75, have a bookoo amount of energy (seriously. its biggest effect I have noticed), and I am sleeping better (and faster) than I have in a long time.
Moreover, Ferris conducted personally experiments where, though only anecdotal, he personally attributes a massive increase in testosterone to ice baths (in his testosterone section). This I have noticed as well
Lastly, Japanese studies have shown that due to the increase in heat, Ice Showers actually make one fall asleep faster at night – even after the shocking experience. Again, I am literally falling asleep 5 minutes after my body becomes re-acclimated.
Ferris recommends that one take a 5-10 minutes shower twice a day, preferrable upon waking and right before bed. I have personally been doing twice a day at 5 -7 minutes. Yet, I will test tonight or tomorrow his more extreme method of taking a literal ice bath where you dump a bunch of conveinent store bags of ice into a tub and fill it with water and “soak” for about 20 minutes. Should be interesting…..
I highly, highly recommend trying this unconventional approach. I know it is painful at first and the “shrinkage” is laughable if not embarrassing, but the after effects are incredible!
If the leaning out continues, I promise to post pictures of progress.
