Sleep is a complex process that our bodies cycle through each night, consisting of four distinct stages. Each stage plays a crucial role in maintaining our health.
This initial Stage marks the transition from wake to sleep and last only several minutes.
Brain Activity: shifts from active beta waves to slower alpha waves and theta waves.
N2 is a deeper sleep stage, accounting for about 50% of total sleep time.
Brain Activity: Sleep Spindles and K-Complexes, which help protect sleep and aid memory consolidation.
Also known as slow wave sleep, or deep sleep, N3 is essential for restorative processes.
Brain Activity: Dominated by Delta Waves, indicated deep sleep.
Rapid Eye Movement (REM) sleep is the final stage in the cycle, occurring about 90 minutes after falling asleep and repeating multiple times.
Brain Activity: Increased Neural activity, memory consolidation.
