To rise the temperature of water it takes 1 joule per 1 mililiter to rise the temperature 1 degrees Celcius.
So, now calculate how much joules you need to keep your bodies temperature constant and
what energy you transform then.
Keep in mind, if you are ill or you got a fever your temperature rises to kill bacteria, which is transferring energie into bacteria which will be dead bodies afterwards.

oooooooh kay
thanks

to be precise due to old informations on my side, i gave you wrong informations.
So here the correction:
1 Joule heats 1 Gramm(1Milliliter) Water by 0.239 K

That just doesn't changes all the in-sigh-ts one can gain by the given task,
but explains why all of the people around us rely on wrong informations.

interesting

of course;
Just a wild guess: you have no clue what i wrote about beforehand?

No, this is truly fascinating. I understand
