This question already has an answer here:
Question is pretty self explanatory. I have a colleague with whom I work closely with and enjoy the company of, however he has recently started exercising and comes to the office smelling quite poorly. In fact, I find that standing within a conversational distance of him is quite unpleasant (to the point where I actively start breathing through my mouth).
Is there any way I can mention this to him without being rude?
edit: I am not in the position to plan a meeting or schedule some other roundabout way to indicate to this person that their hygiene isn't up to par. The linked question contains a similar problem, but I can't utilize the same kind of solutions suggested.
