The Sleep-Wake Cycle: A Dance of Harmony

The sleep-wake cycle is a rhythmic dance orchestrated by the body’s internal clock, known as the circadian rhythm. This delicate balance is governed by complex physiological processes, influenced by factors such as light exposure, temperature, and hormones. The two main stages of sleep—rapid eye movement (REM) and non-rapid eye movement (NREM)—alternate in cycles throughout the night, each playing a vital role in maintaining health:

  1. NREM Sleep: Divided into three stages, NREM sleep is essential for physical restoration, immune system function, and memory consolidation.
  2. REM Sleep: Often referred to as “dream sleep,” REM sleep is crucial for cognitive processes, emotional regulation, and creative thinking.
