Heat doesn’t come from nowhere. If a fart increases the temperature of the room, then it must decrease the temperature of the body it escaped from.

So, if you’re freezing, you should hold on to those little hugs of warmth as long as possible.

Top comment is wrong: the short answer to the post title is a hard “yes” due to enthalpy of solvation. The process of fart mixing into ambient air generates heat.

The answer to your followup question would require some modeling — with the main factors being fart composition, body mass, thermal gradient, and room size.

The fart doesn’t decrease the body temperature, but it does (marginally) reduce your body mass, and therefore your body’s capacity to “carry” heat. If you’re hypothermic, your fart will most likely still be body temperature, as your core temperature remains at the correct temperature as long as possible, even sacrificing other areas if necessary.

If you’re hypothermic to the point where your fart is cold, it might be beneficial to let one rip if you’re entering a warmer area, so that your body no longer has to heat up the gas as well. If you’re somewhere cold, the fart probably won’t make a difference.

They were part of you that was already at a constant temperature. It would distribute the heat quicker but the overall heat transfer is the same.

One factor that changes this is that because your body maintains a constant temperature, releasing heat faster would cause your body to generate more heat to compensate.

Extruded? Did you shit your pants?

It does if you light it

This is an interesting detail, but there is akready so much written here, and lots wrong, that giving an answer that really helps would be way too much effort.

But in real world terms it really does not matter at all and you would have a very hard time even measuring any sort of effect.

It’s purely anecdotal, but my farts dramatically increase the overall temperature of my apartment. It’s hell during the summer, but admittedly kinda nice when it’s cold out.
