Sleep is one of the most important parts of a healthy lifestyle, yet many people ignore it. Proper sleep gives rest to the body and mind, helping us to feel fresh and active. Children and students need 7–9 hours of sleep daily for proper growth and learning. Lack of sleep causes tiredness, irritation, weak memory, and poor concentration. It can also lead to serious health issues like high blood pressure, obesity, and heart problems. Nowadays, due to mobile phones, television, and late-night activities, many students do not get enough sleep, which badly affects their studies and health. A regular sleep schedule, going to bed early, and waking up early are the best ways to stay healthy. Sleep is not a waste of time; it is a natural medicine for our body. Good sleep ensures a strong body, sharp mind, and happy life.
