Normal, healthy sleep architecture must include which sleep stage/s? (There may be more than one correct answer. Please select all correct answers.)Group of answer choicesN2REMN1N3

Normal, healthy sleep architecture includes all of the following sleep stages: N1, N2, N3, and REM.

1. N1: This is the first stage of sleep, also known as light sleep. It's the stage between being awake and falling asleep.

2. N2: This is the second stage of sleep and takes up the majority of the sleep cycle. During this stage, the body temperature drops and heart rate slows down.

3. N3: This is the third stage of sleep, also known as deep sleep. It's the most restorative stage of sleep where the body repairs and regrows tissues, builds bone and muscle, and strengthens the immune system.

4. REM (Rapid Eye Movement): This is the stage of sleep where most dreaming occurs. It's essential for processing emotions and storing memories.

So, all of these stages (N1, N2, N3, and REM) are necessary for normal, healthy sleep architecture.
