What are the Stages of Sleep?

Sleep is a natural state of rest that is essential for our physical and mental wellbeing. It is a complex process that involves a range of different stages. These stages are divided into two categories: Non-REM (NREM) sleep and REM (Rapid Eye Movement) sleep. In this article, we will explore the various stages of sleep and how they affect our health.

The Stages of Non-REM Sleep

Non-REM sleep is divided into four stages. Each stage is characterized by different brain wave patterns and body movements.

Stage 1: Light Sleep

Stage 1 is the lightest stage of sleep. During this stage, our brain waves slow down and our body movements become less frequent. This is the first stage of sleep and typically lasts for 5-10 minutes.

Stage 2: Deeper Sleep

Stage 2 is a deeper stage of sleep. During this stage, our brain waves slow down even further and our body movements become even less frequent. This stage typically lasts for 10-25 minutes.

Stage 3: Deep Sleep

Stage 3 is the deepest stage of sleep. During this stage, our brain waves slow down even further and our body movements become almost non-existent. This stage typically lasts for 20-40 minutes.

Stage 4: Dream Sleep

Stage 4 is the final stage of Non-REM sleep. During this stage, our brain waves become very slow and our body movements become almost non-existent. This stage typically lasts for 10-25 minutes.

The Stages of REM Sleep

REM sleep is the second stage of sleep and is characterized by rapid eye movements, increased brain activity, and vivid dreaming. This stage typically lasts for 10-25 minutes and is important for consolidating memories and learning new information.
