If you are blessed with a good health you may see tiredness as a sort of whim, in which case I can tell you that it is an ironhard fact of life, which you cannot ignore!

As I see it, depending on the situation the dom is supposed to know the sub enough to know what this tiredness is about, and to make a qualified reaction to the situation.
But we're definitely not talking about chronic health issues. We're in the realm of a hard day at work, school, or even play. Everything is situational and this is outside the previously presumed bounds of the original question. Nothing I've said about it applies to health concerns.

I've already noted that there's a relevent (spelled correctly this time,) distinction between merely not being in the mood and real concerns. I've also noted the distinction between 24/7 relationships and only-in-the-bedroom relationships.
