Blood pressure drops slightly, giving the vascular system a necessary break. During this initial stage, the body and mind transition from full wakefulness toward genuine restoration, performing a series of subtle but critical housekeeping functions.
Light Sleep Stage Brain Waves and Their Functions
By respecting the delicate nature of this phase, you ensure that the subsequent stages of deep and REM sleep can proceed unhindered, leading to genuinely restorative nights. This often results in a feeling of grogginess or "sleep inertia," even after spending a seemingly adequate number of hours in bed, highlighting the importance of protecting this fragile phase.
