I used to be very careful when changing lenses outdoors, as Andy suggests, keep the camera body facing down. I chose to change lenses in the car wherever possible away from dusty environments such as dry and windy places.
I am much more cool now willing to change lens almost anywhere but always keeping that body facing down.
No damage will be caused by dust other than inconvenience of sensor cleaning more often. I must admit after 10,000 actuations I have only cleaned the sensor once at 4,000ish but I am about to check and may clean out of routine shortly.
