This is a fancier way of saying that it’s unfortunate that naps don’t make one feel more energetic afterward:

So, if you read through the Philokalia, it is very common to find the same author alternating between talking of thoughts (logismoi here referring to negative, vicious thoughts that could lead you astray) and demons. Acedia, the vice of listlessness and despondency, is called, for instance, ‘the noonday demon.’ Sometimes it is treated as an internal struggle; other times it reads as if a personified demon is the cause of these temptations; if Graiver is right, then these are merely two ways of experiencing and conceptualizing the same phenomenon.

— Jared Henderson, Asceticism of the Mind

I give them grief, but I do love afternoon naps.
