Physical health refers to the state of the body's functional and metabolic efficiency. It is influenced by various factors, including nutrition, exercise, sleep, and genetics. A well-balanced diet that provides the necessary nutrients, vitamins, and minerals is essential for good health. It helps in maintaining a healthy weight, reducing the risk of chronic diseases such as obesity, diabetes, heart disease, and stroke. Regular exercise, including both cardio and strength training, helps in improving cardiovascular health, building muscle mass, and boosting metabolism. Adequate sleep is also crucial for physical health, as it allows the body to rest and repair damaged tissues.
