The REM sleep alternates with the three stages of the NREM Sleep, which is divided into N1 (sleep onset and transitional) that lasts 1 to 7 minutes, N2, a deeper stage of sleep that is 10 to 25 minutes in duration, and the N3 (delta sleep
) which is the deepest stage of the three stages, that occurs for 20 to 40 minutes (Spriggs, 2014).
In patients with depression, SWA and delta sleep

Cytokines produced by cells of the immune and nervous systems (particularly IL-1-beta and TNF-alpha) regulate sleep; signal neuroendocrine, autonomic, and limbic and cortical areas of the CNS to affect neural activity; and modify behaviors, hormone release, and autonomic function.(11,17-19) Growth hormone production depends upon the presence of delta sleep
, which is reduced in an inflammatory state.

The clinician should rule out OSA/ upper airway resistance as a reason for disrupting the delta sleep
Lack of awakening in response to noise and light stimuli may be reflective of sleep stage, as a person is less responsive to stimuli in delta sleep
(Carskadon & Dement, 2005).
