Sleep is essential for physical and mental health, supporting immune function, memory, mood, and cognitive performance. During sleep, the body repairs tissues, consolidates memories, and regulates hormones. Poor sleep can lead to issues like weakened immunity, mood disorders, and decreased focus. To improve sleep quality, **establish a consistent schedule** by going to bed and waking up at the same time daily. **Create a calming bedtime routine**—limit screen time, read, or practice relaxation techniques. **Optimize your sleep environment** by keeping it cool, dark, and quiet. Reducing caffeine intake and avoiding heavy meals before bed can also promote restful sleep, leading to better overall health.
