Why do we blow on food to cool it down yet blow on our hands to warm them up?
The air you blow is about 30C, if your hands are cold, their temperature will be lower than that, therefore, blowing 30 C on them will warm them up. If your food is too hot, it is above 30C (can go as high as 100C or more), blowing 30C on them will cool the food faster.
Does Blowing on a cup of tea make it cooler?
