On the contrary, whichever wildernesses most shaped our hearing were not silent places. The places people lived, that we know of, in the ice ages were quite wet. Rivers and even streams are constant sources of noise.
There are issues of levels and likely specific frequencies, but complete silence puts the stoppered ear further from the conditions in which it formed as well.
To disclose, I have worked in call centers for a cumulative decade and found that ear infections were more likely if I did not switch which ear was covered at least every week, when ear-covering headsets were the only option. I expect that stopping up ears overnight will have a similar consequence for at least a portion of the population. And so I advise caution.

I do not find fault in that action.
