Sleep science is the study of how and why we sleep, focusing on the biological, psychological, and social aspects of sleep. Researchers explore the different stages of sleep, such as REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement), to understand their roles in memory, learning, and overall health. Understanding sleep science helps us recognize the importance of good sleep hygiene, which includes practices like maintaining a consistent sleep schedule and creating a comfortable sleep environment. By applying these principles, we can improve our sleep quality and, in turn, enhance our daily functioning and well-being.
