Bedtime procrastination — delaying sleep for no real reason while knowing it'll hurt the next day — is linked to end-of-day depletion of self-regulation, especially in high-pressure jobs; noticing it and building a calm pre-bed routine helps limit it.

Both citations in the post are checkable and correctly attributed: the definition does come from Kroese et al. (Frontiers in Psychology, 2014, "Bedtime procrastination: introducing a new area of procrastination"), which shows bedtime procrastination predicts self-reported insufficient sleep beyond demographics and general self-regulation; and the study on high-pressure jobs and "resource depletion" is real (Nauts, Kamphorst et al., 2018, Frontiers in Psychology, on cumulative end-of-day depletion). The picture isn't unanimous, though: a later study in the same field (Frontiers in Psychology, 2018, daily diary design) finds the opposite of the expected depletion effect — employees procrastinated more on evenings when they reported MORE self-regulatory resources available — and attributes much of the phenomenon to chronotype rather than willpower burnout. The phenomenon itself (delaying bed despite knowing the cost) is thus solidly established and tied to worse sleep; the exact mechanism (self-regulation depletion, chronotype, or something else) is still debated within the research itself. The practical advice offered (calm routine, put screens away) remains reasonable independent of that mechanistic debate.
