> Deep sleep is not improved by consistent sleep/wake times, and adjustments to noise/temperature/light conditions?

Deep sleep definitely benefits from consistent sleep/wake times. Your body tries to play catch up if you break from your normal rhythm but it’s not entirely effective.

I think the parent comment might be exaggerating the futility of sleep hygiene because they have a product to sell. :) Proper sleep timing, duration, and sleep hygiene are inarguably valuable for proper sleep architecture.

I'm not saying sleep hygiene is futile, I specifically say it is important, and sleep hygiene improves the potential for deep sleep, it does not directly improve deep sleep.
