Stages of Sleep

Explore the Journey of Sleep

Understanding the stages of sleep help one to understand how important uninterrupted sleep is for your body to refresh, revitalise and get rest.

Phase 1:

As you begin to drift into slumber, Stage 1 sets the stage. Your eyes gently close, and awakening is effortless. Yet, if roused from this phase, you might sense a lingering feeling of unrest. Lasting around five to ten minutes, you may experience sensations of falling, occasionally prompting sudden movements known as hypnic myoclonia.

Phase 2:

Transitioning into a lighter realm of sleep, Stage 2 marks a subtle shift. Here, your heartbeat slows, and body temperature decreases, signalling the onset of deeper sleep.

Phases 3 and 4:

Delve deeper into the abyss of slumber with Stages 3 and 4, where profound restfulness awaits. Stage 4, in particular, plunges you into an even more profound state. It is during these stages that REM (Rapid Eye Movement) sleep occurs, accompanied by slow-wave delta activity. Should you awaken during this period, a brief sense of disorientation may linger.

Phase 5:

The pinnacle of the sleep cycle, Stage 5, also known as REM sleep, ushers in a realm of vivid dreams and heightened physiological activity. Characterized by rapid eye movements, increased respiration, and heightened brain activity, REM sleep stimulates the mind while inducing muscular relaxation. Despite the brain’s heightened activity, voluntary muscles remain immobilized—a protective mechanism ensuring your safety as you traverse the realm of dreams.

The longer you have uninterrupted sleep, the more phases of Deep and REM sleep you experience which result in quality sleep where you wake up refreshed. Each time you wake up, even just enough to change your position, you restart the phases and diminish the amount of Deep and REM sleep.
