Sleep is one of the most essential yet often overlooked parts of a healthy lifestyle. While many people focus on diet and exercise, sleep plays an equally important role in maintaining both physical and mental well-being. It is during sleep that your body repairs itself, your brain processes information, and your energy levels are restored for the next day.
Understanding the importance of sleep can help you make better choices that improve your overall health, productivity, and quality of life.

Without enough sleep, the body struggles to function properly.
