Tidur gelombang lambat

Burung-burung unta sedang tidur dengan tahap tidur REM dan tidur gelombang lambat[1]

Tidur gelombang lambat (bahasa Inggris: slow-wave sleep, disingkat SWS), sering juga disebut tidur nyenyak, merupakan tahap tiga pada tidur non-REM (non-rapid eye movement).[2] Pada awalnya, tidur gelombang lambat mencakup tahap 3 (dengan 20-50 persen aktivitas gelombang delta) dan tahap 4 (dengan lebih dari 50% gelombang delta).[3] Namun, semenjak tahun 2008, American Academy of Sleep Medicine (AASM) tidak lagi menganggap tahap 4 sebagai tahap yang terpisah.[4][5][6]

Tahap tidur ini disebut tidur gelombang lambat karena aktivitas elektroensefalografi mengalami sinkronisasi dan menghasilkan gelombang-gelombang lambat dengan frekuensi 0,5-2 Hz.
