Why Is Physical Activity Important?

Physical activity is important because it increases a person's chances of a long life, improves self-esteem and reduces depression levels, according to the United States Department of Agriculture's ChooseMyPlate.gov website. This website is designed to help individuals make wise health choices.

Physical activity also improves nightly sleep, strengthens muscles and bones, and assists in attaining and maintaining a healthy weight. Exercise provides several other health benefits, such as reducing blood pressure, improving balance and increasing overall energy levels, says the Seattle and King County Public Health's website. This website also states that 30 minutes of daily physical activity is sufficient to realize key health benefits.
