Each stage of sleep plays a crucial role in our overall well-being. Here’s a breakdown of their importance:
- Stage 1: This is the transition period from wakefulness to sleep. It’s essential for relaxation.
- Stage 2: This stage helps consolidate memories and learning.
- Stage 3: Deep sleep is vital for physical restoration and growth.
