Research suggests that anesthesia, including sevoflurane, may disrupt the normal sleep architecture. Sleep is typically characterized by distinct stages, including REM (rapid eye movement) and non-REM sleep. Anesthesia may alter the balance between these stages, potentially impacting the overall quality of sleep. Therefore, while sevoflurane induces a sleep-like state, it does not necessarily contribute to the same benefits as natural sleep.
