Sleep onset latency
Sleep onset latency (pronounced: /ˈsliːp ˈɒnˌsɛt ˈlætənsi/) is a term used in sleep science to describe the length of time that it takes for an individual to transition from full wakefulness to sleep.
Etymology
The term "sleep onset latency" is derived from the English words "sleep" (from Old English slēp), "onset" (from Old English onsettan), and "latency" (from Latin latens meaning "lying hidden").
Definition
Sleep onset latency is typically measured in minutes and is considered to be the period from the moment an individual attempts to fall asleep until they actually fall asleep. It is a key metric used in polysomnography, the study of sleep, and is often used to diagnose sleep disorders such as insomnia or hypersomnia.
