Yes, and it's effective at burning back fat. Burning *fat* , not calories.
this is one reason swimmers burn so many calories. the water is cold and the body has to work over time to keep body temp up.
Extracts from the study:
<snip> Eleven lean male subjects (height: 184±3 cm; body mass: 77.7±2.7 kg; BMI: 22.9±0.6 kg/m2; age: 21.7±0.6 years), not using any medications and not seen by a MD in the last three years participated in this study. Subjects stayed twice in the respiration chambers of the department of Human Biology, Maastricht University, wearing standardized clothing. The two conditions are defined as follows: 1) baseline: 34 hours measurement of energy expenditure at energy balance, comfortable temperature (22°C); 2) cold exposure for 82 hours in energy balance, mild cold without shivering (16°C). Macro-nutrient composition was equal in both conditions: 47, 38, and 15% energy from carbohydrate, fat, and protein, respectively. After each respiration chamber stay a muscle biopsy was taken, from M. vastus lateralis according to the technique of Bergström [24]. A part of the biopsy was stored in a preservation medium for mitochondrial uncoupling measurement, the rest of the biopsy was quickly frozen in liquid nitrogen for protein quantification and CS activity analyses. <snip>
<snip>The increase in energy expenditure, 0.32 MJ/day <snip>
If my conversion is correct, thats 76 calories - over a whole day at a reduced temperature. So, as has been said, the impact of a shower is negligible and you would be better off doing a few jumping jacks or burpees.0 -
I take cold showers for er...other reasons.
But I suppose that would explain my shiny hair.0 -

I briefly dated a Jamaican guy that only takes cold/cool showers. Not only is it good for hair(hot water can damage it) its great for skin. He had the softest skin EVER.
I've heard the theory with cold showers for calorie burns is that our body needs extra fuel(calories) to heat itself back up. Not sure a quick cold rinse is enough.0 -
Dr. Oz says drinking really cold water uses up more calories too. Maybe.0

Only if shivering is a form of exercise.0

Q=mc delta T = energy = mass x specific heat capacity x change in temp
A human is a giant water bag, so lets use the specific heat of water.
4.186 Joules/gram degrees C. Next, lets say the person goes into a cold shower for 1 minute as you described. First of all, their entire body can not and will not change it's entire temperature in that amount of time, but lets pretend in your scenario it is plausible idea. We now need a mass. Lets say a person of 180lbs which is 81646.6, but we'll round it to 81647grams. Okay. Next you need a temperature change. Hypothermia kicks in around 95F. Lets put 99 as our high and 96 as low. 37.22 to 35.56 = 1.66 C change.
So Q = 4.186J/gC x 81647g x 1.66C =567345J=135 calories.
So under the delusion that in 1 minute, our entire core body temperature OF ALL OUR BODY MASS dropped from 99F to 96F, then yes our body would burn 135 calories. That being said, if you think that is remotely possible with the limited flow of a shower of water hitting you at 70F exposed to open air in a room of 75F and the limited physical contact it has - you're an idiot.
As per survival manuals, in say 70F water FULLY IMMERSED it will take approximately 20-30 minutes to drop your temp below 96 degrees. THIS change WOULD give you the calorie deficit calculated.
So, if you take a person, put them in a cold BATH, fully immersed to the neck, and MAINTAIN the temperature at 70F for 20-30 minutes, then yes, at that point, they will have burned 135 calories.
Edit: and entered hypothermia
This is the most intelligent post I have seen on MFP. Well done sir.
I also like doing one minute of cold water following a workout, if nothing else it cools me down so I do not perspire while getting dressed and hauling *kitten* back to work.
In the 4HB book Ferris talks about cold water baths if anyone wants further reading.0 -
All those calculations are based on body temperature, but the skin temp is much lower than that ! and when you are cold your blood vessels near the skin contract to lose less heat (less surface area). And fat insulates the heat as well. When I was little I was shivering at the pool while all the other kids felt comfortable. I guess you have to be very skinny to burn fat this way

The science on this is pretty solid. Some people take ice baths. But all of it is peripheral, in other words, it helps but it doesn't stand alone at all.
You always need to eat right and exercise.0 -
I agree with dmpizza, these little tricks may help but if you want some solid, permanent results you've got to start eating right and working out. (Says the noob who just joined MFP >.>)
On a side note, I don't think I could do this, I hate the cold. I'd rather be too hot than too cold.0 -

Gosh the big numbers. I'm used to using kg and kJs. Very nice!
Actually human body is estimated to have a specific heat capacity of around 3480 j/g-1c-1, you don't need to assume a giant water ball. However study on mice showed that high body fat mice has much lower heat capacity compared to lean mice so your numbers will get even tinier on a hypothetical near hypothermia scenario :drinker:
Cold water is great for many things, helping with blood circulation and water retention is one them but it's definitely not burning calories.
Like Sara said, do jumping jacks people -.-0 -

What kind of science is that? Can you cite the articles? Besides some authors with fad diets?0 -
That's as patently absurd as the science behind this little ditty.

Page 128-131 of the book The 4 hour body by Timothy Ferris explains the science between it and the fat burning fat that is activated by ice water. He did this study with Ray Cronise, a NASA scientist who specialized in biophysics and analytical chem.
It's in the ice age chapter. They repeated this study several times to look at many angles, and the ice cold water, on the upper neck and back, activate fat burning fat.
Yes, you need to eat right and exercise, but for a 5 minutes of an ice cold shower to stimulate BAT, sure, why not? can you do several jumping jacks? absolutely. But will jumping jacks stimulate fat burning fat? You don't need to go overboard with bags of ice in your tub. just 5-10 mins.
I think I will go on the word of a NASA scientist who did this testing multiple times.0 -

You forgot the part that it specifically burns fat. Jumping jacks burn calories. cold water burns fat.0 -

I guess you are basing it on this:A team led by Sven Enerbäck, a medical geneticist at the University of Gothenburg in Sweden, found that when subjects spent 2 hours in a cold room wearing thin clothing and intermittently soaking their feet in ice water, their brown fat burned 15 times more energy than it did at room temperature. One subject had enough brown fat to lose 8 to 9 pounds per year.
(...)
mice fed a high-fat diet and kept at room temperature ended up nearly four times heavier than mice fed the same diet and housed at 39 F. Researchers estimate that just 2 ounces of active brown fat could burn 300 to 500 calories a day. "You don't need much to have a profound effect on your body's metabolism," Cypess says.

That's a huge discovery! Not. They are only a bit more informed about why the BMR is increased in winters. It's quite possible to measure the BMR of people living in cold climates already. As brown fat is rumored to be activated as a heating mechanism against cold, that's already calculated in. If you want to live in 39F (that's like 4*C) to burn 300-500 calories extra, you can move north and save on heating bills.
And sadly, above "studies" are all about calories burned, nor fat loss.
I'm seriously not trying to be a smartass but this is turning into a super fad diet myth.0 -

On a deficit, what do you think happens - when you burn calories? And you are sort of missing the point here - lets say you take a long cold shower for 60 minutes - you would burn 12 calories of fat. Have at it!0 -

ETA: And also various post mortem studies showed that brown fat tissue decreases over age and is not evenly distributed in humans.0 -
Can't say I heard of the shower, but I read somewhere that they conducted a study that you burn calories by adding ice to your water. Don't know if that's true or not, sounds crazy to me. But wouldn't hurt to try it. Lol.
Guess you can burn some calories in a cold shower if you are shivering the entire time. :P0 -
No not true, if that were the case I would be a six by now...due to my cold showers in summer time....0

thats the reason swimmers burn so many calories?? it couldn't possibly be the full body work outs that go on for hours in anerobic conditions.
nope. the water's cold. thats why phelps and locht looks like they do.0 -
