Physical activity is defined as any body movement produced by the action of our muscles.
In a society where we depend so much on cars and passive forms of entertainment, it is easy to ignore our need to be active. Regular physical activity improves our health in many ways. Physically active people have lower risk of heart disease, diabetes and other chronic diseases. They also sleep better and have better emotional health. Physical activity improves physical fitness, which means that physically active people have more energy and do not tire as easily as less active people.
