Understanding Sleep Phases

Sleep is a complex state with distinct phases, including non-REM and REM, each playing a crucial role in brain function and restoration. A perfect night's sleep typically lasts around 7.5 to 8 hours, cycling through various stages that include deep slow wave sleep, which helps cleanse the brain. Interestingly, studies show that even in a controlled environment, individuals naturally settle into an average of 8 hours and 15 minutes of sleep, highlighting the body’s intrinsic need for rest.
