Honestly there are many scenarios you could make from this, but a personal favourite that has been in my mind for a bit is Zedaph finding out. Zedaph who lives to see, to know, to experiment and to fix. Don't ask them how (they can never tell anyone lest the information somehow comes across Impulse, who they are sure would lecture them to the regularly sized moon and back), but somehow Zed and Tango found out the latter is immune to lava.

So after particularly chilly days (for Tango meaning: a light spring day), it would not be uncommon to be directed to the 'bathhouse' Zed had built, after Impulse deemed the two of them simply making a lava bath in Tango's own base would be too risky, if you were looking for the netherborn. In these moments, he would indeed often be found in said bathhouse, where he could be seen with just barely his eyes and tips of his ears poking out of the mildly threatening pool of lava, until he had to come up for air and to greet whatever guest decided to visit him in his little slice of nether-comfort amongst the overworld.

But take this into account: imagine Hermitcraft is one of those places where for a period of time the sun does not go down, but that also means there is a period where the sun does not come up.

So Bdubs just has a few months a year where he does not shreep sleep but then half a year later he literally hibernates.

I like to think the other hermits would help him 'prep' for the hibernation months and check up on him in whatever hidey hole he picked out during.
