**Reality: Mixed.** The advice intends to prevent resentment from festering. In practice, forcing resolution when both partners are flooded makes things worse, not better. Gottman's research suggests that sometimes sleep is exactly what's needed — the nervous system calms down, and problems look different in the morning. The real principle underneath it: don't let resentment go unaddressed for days or weeks.

The advice never to go to bed angry earns Pop Psychology. Forcing a resolution late at night often backfires: once a partner is physiologically flooded, overwhelmed and unable to think clearly, the conversation tends to get worse rather than better. Gottman's research supports taking a real break and returning when both people have calmed down, which sometimes means sleeping first. Evidence on whether sleep itself entrenches or eases negative feelings is mixed. The useful kernel is to repair before resentment hardens, but the literal rule, resolve everything before sleep, is not supported.
