Morphology
whatever + help + you + sleep + at + night
The literal composition ('whatever' + 'helps you sleep at night') yields an obvious meaning ('anything that allows you to sleep'), so a learner who knows the words can recover a basic sense. However, the typical use is a dismissive/pragmatic stance meaning 'do what makes you feel better' or 'I don't accept your justification,' which relies on conversational implicature and tone and is not fully predictable from the constituent meanings alone.
Etymology
Whatever helps you sleep at night comes from the image of someone lying in bed, worried, who uses a small excuse or comfort to quiet their mind so they can sleep. So people say it to mean 'do what makes you feel better', but often to show doubt.
