does it help to hold your breath to avoid second hand smoke?

I have never smoked in my life, and with every year my attitude and tolerance for smoking becomes worse and less (sorry, all smokers out there!). In the last little while, I realized that I actually unconsciously hold my breath every time I pass someone who smokes in the street. Does this significantly do anything in terms of benefiting me and helping to avoid the dangers of second-hand smoke, or am I just fooling myself?
