Types and Categories
Different Stages of Sleep
- REM Sleep: Rapid Eye Movement sleep is characterized by vivid dreams and plays a crucial role in cognitive function and memory consolidation.

- Cognitive Impairment: Difficulty concentrating, memory lapses, or poor decision-making skills.
Effects on Physical Health
- Weakened Immune System: Chronic sleep deprivation can compromise the body’s ability to fight off infections.
