Plan the work and environment very well to avoid interruptions. Still if it comes, welcome the interruption, postpone addressing it if you can, address it if can't be missed. But most important thing is to don't react to it happening, so you can switch back to your tasks again with same rigor.

this was key for me, my reaction to being interrupted was impacting me more than the actual interruption.
