Introduction

Sleep is essential for maintaining overall health and well-being. It helps the body recover, boosts brain function, and enhances mood. However, with busy schedules and demanding lifestyles, many people struggle to get enough sleep. Understanding how much sleep is necessary for different age groups can help improve health and daily performance.

Why is Sleep Essential for Overall Health?

Sleep plays a vital role in various bodily functions, including brain function, metabolism, and immune system regulation. It helps consolidate memories, repair tissues, and regulate hormones. Lack of sleep can lead to a weakened immune system, increased stress, weight gain, and a higher risk of chronic conditions like diabetes and heart disease. Ensuring adequate sleep is crucial for mental and physical well-being.
