A good night’s sleep is often underestimated in today’s fast-paced world. However, insufficient sleep can harm your health and well-being in the long run.

Your mood, productivity, and general health are significantly impacted by your sleep quality. Therefore, you must learn about the various stages of sleep to understand how to enhance your sleep cycle and overcome the issues related to lack of sleep.

This post will examine the four stages of sleep – awake, light sleep, deep sleep, and REM sleep and how they affect the quality of your sleep.

Stage 1- Awake Stage

The first stage of the sleep cycle is the awake stage.

In this stage your respiration, eye movements, pulse rate, and muscular tension all settle down, which usually lasts less than 10 minutes.

Also, the general muscle tension and core body temperature drastically decrease during this stage.

Stage 2- Light Sleep

The second stage of the sleep cycle is Light sleep.

As you transition into this stage, your body temperature decreases, and your brain activity continues to slow down. 
Most of your sleep time is spent during this phase.

During light sleep, the body is susceptible to external stimuli, and you may experience brief periods of awakening.

Stage 3- Deep Sleep

The third stage of the sleep cycle is the Deep sleep.

During this phase, also called slow wave sleep, your body and mind rejuvenate and repair itself. 
Your brain waves slow down, and your muscles relax. This is the most important phase of the sleep cycle. At this stage your body restores tissues, boosts the immune system, and consolidates memories.

Have you ever wondered why sometimes, it becomes so difficult to get up? Well, that’s because it’s the deep sleep stage and at this point, your brain generates sluggish delta waves, making it difficult to wake up. 
A night of restful deep sleep will make you feel rejuvenated and fresh the next day.

Stage 4- REM Sleep

The fourth phase of sleep is the REM (Rapid Eye Movement). In this stage your eyes move quickly, and your brain becomes extremely active.

Memory consolidation, emotional management, and cognitive performance are important during this stage. During REM sleep, your body is temporarily paralyzed to prevent you from acting out your dreams.

It is the stage in which you have vivid dreams, and if you wake up during this stage, you may remember specifics from your dream.

Final Thoughts

To improve your sleep quality and general well-being you must understand the various stages of sleep and the significance of sleep cycles.

Although an average adult has 4-6 sleep cycles per night, the precise number might vary based on many circumstances. Each stage of the sleep cycle—awake, light, deep, and REM sleep—is important for your physical and mental recovery.

By creating a comfortable environment and following a healthy ritual, you can work toward getting enough sleep cycles and feel refreshed and rejuvenated when you wake up.
