Sleep quality significantly affects overall health, impacting cognitive function, immune response, and emotional well-being. Poor sleep can lead to increased stress levels, diminished productivity, and a higher risk of chronic conditions such as obesity and diabetes. Quality sleep promotes recovery and repair within the body, enhances memory consolidation, and regulates hormone production, particularly those related to appetite and stress. To maintain optimal health, individuals should prioritize good sleep practices, such as establishing a consistent sleep schedule and creating a conducive sleep environment.
