SLEEP ARCHITECTURE e term ‘sleep architecture’ refers to the structural organisation of normal sleep. In the same way that your circadian rhythm can be characterized by a set of actions occurring in a cycle, so can the structure of your sleep, which occurs in different stages throughout the night. Sleep can be divided into two groups: non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM). During NREM sleep your breathing and heart rate become slow and regular, your blood pressure drops and you remain relatively still.
