I get that often. I assume that when there is travel involves (esp air travel) a big piece is exposure to new viruses and bacteria + stress. if you get it even without travel: before your holidays do you have to crunch to get things done before you leave? The stress, reduced sleep could be lowering your immunity.

Not so much crunch, but I do stress over leaving WIP in a clean state that colleagues can pick up while I'm gone.

That's a useful insight - thanks.
