Sleep is vital for good health and well-being. It boosts the immune system, repairs damaged tissues and consolidates memories. Lack of sleep increases the risk of many health issues, including obesity, diabetes, cardiovascular disease, and depression. It can also cause cognitive deficits, impaired decision-making, and reduced productivity. Developing a consistent sleep schedule, optimising sleep environment, reducing caffeine intake, and limiting exposure to screens at night are beneficial strategies to improve sleep quality. Getting enough sleep helps regulate hormone levels, leading to better overall health and energy levels throughout the day. It is crucial for physical and mental health, and overall quality of life.
