The effect of hand fans for better breathing in emergencies Suppose I am in a room or system with a lot of smoke and it is difficult to breathe. If I put a hand fan in front of my face, does the wind from the fan blow the smoke away from my face, making it easier for me to breathe, or does it increase the intensity of the smoke and make it harder for me to breathe? How can this phenomenon be explained in terms of physics?
