Doorslapen

Doorslapen is a Dutch verb meaning to sleep through the night or a disturbance without waking, i.e., to remain asleep until the morning. The term is used to describe uninterrupted or extended sleep and is common in everyday speech in the Netherlands and Flanders. It implies that external stimuli such as noise, light, or alarms do not interrupt the sleeper.

Usage and nuance: Doorslapen denotes a state of maintained sleep through the night or long enough to miss the usual waking cues. It is a colloquial expression rather than a medical term, and speakers may use it to express satisfaction with their sleep or to describe a day after having slept for a full night.

Etymology and language context: The word is a compound of door (through) and slapen (to sleep). As a common expression in Dutch, it appears in informal conversation, media reporting on sleep, and parenting or lifestyle contexts. It is typically contrasted with waking during the night or with difficulty staying asleep.

Related concepts: In sleep science, the idea behind doorslapen relates to sleep continuity and arousal threshold—the likelihood that a person remains asleep in response to disturbances. Factors that influence doorslapen include sleep pressure, circadian rhythm, environment (noise, light, temperature), caffeine or alcohol use, stress, and age. Persistent difficulty sleeping through the night may be discussed separately as part of sleep disorders or insomnia.
