How many calories burned shivering and

Shivering: 100 calories in 15 minutes!

I think I prefer the bathercise option.

Sucking ice cubes should be better than drinking cold water, because you have the latent heat of fusion to overcome.

If cold water would do that in theory wouldnt hot also do the same? Besides it being significantly harder to swallow alot of hot tea fast XD

No. Because the hot tea would actually provide energy to heat your body up so your body wouldn't have to spend so many calories doing that. So, if the theory was correct, hot water would actually have positive calories. But food calories are actually kilocalories, so both the "hot water effect" and the "cold water effect" ought to be negligible.

And I appear to use the word "actually" way too much.

When I said calories I was meaning kilocalories. Raising the temperature of 1 liter by 33 degrees Celsius expends 33 kilocalories. So if you drank 8 liters of ice water in theory it would take at least 264 kilocalories to maintain your body temp. I just said calories because no one actually says kilocalories :-)

Wow @ShammersPink you've obviously looked into all of this

The bathercise thing was in a TV programme earlier this year and has been my excuse for wallowing in the bath regularly during my diet!

The tube thing is from drunken late night conversations on the tube home, the ice thing is vaguely remembered school physics (plus sucking ice cubes to cool down when I had a high fever recently!) and the shivering was recourse to Dr Google!

True...phase transitions take a huge amount of energy which is why evaporation of sweat is so good at transferring energy away from your body.

Taking a long hot bath can burn 140 calories, allegedly:

Bathercise.

That doesn't make a lot of sense to me. If you are immersed in warm water your body would have to work less hard to maintain your body temp above ambient so I'd think if anything you'd burn fewer calories than if you had spent the same time at room temp.

Ice bath here i come

In before ice bath challenge for obesity awareness >.>

I'd actually be really curious if there have been studies measuring the BMR of a person at different ambient temperatures. Would be curious if there is a noticeable difference between someone in a 4 degree room, a 25 degree room and a 37 degree room. I'd say bath but a 4 degree bath for 24 hours would probably kill them which would make their BMR zero which would throw off the measurement...and be unethical a bit. But if they do that they should at least take the 4 degree measurement last then.
