Does blowing on our hot food before we put it into our mouths actually make a difference to how hot it is? (feddit.uk)

I'm thinking that no, it doesn't. Which begs the question of why we do it? Is it a psychological thing?

The simple answer is that it takes time. You've removed it from the hot pile of food and given it a few moments to cool, surrounded by cooler air.

I bet if you did an experiment where you blow on on spoonful while it waits and with the next one you just pause without the blowing, you'd find little difference between the two experiences.

You know how you wind can make you feel pretty cold even when it's warm outside? The effect is even stronger for food, since the ratio of surface area to volume is bigger, and the temperature difference is much bigger.
