Why Should People Be Active? | Active People, Healthy Nation

Background

Regular physical activity is one of the most important things people can do to improve their health. However, too few Americans get the recommended amount of physical activity. Currently, in the U.S.:

• Only about 1 in 4 adults fully meet physical activity guidelines for aerobic and muscle-strengthening activities.
• Only 1 in 6 high school students fully meet these guidelines.

Immediate and long-term benefits

Regular physical activity has many health benefits.

For adults

Immediate benefits

A single session of moderate-to-vigorous physical activity:

• Improves sleep quality.
• Reduces feelings of anxiety.
• Reduces blood pressure.

Long-term benefits

Regular physical activity:

• Reduces risk of developing dementia, including Alzheimer’s disease.
• Reduces risk of depression.
• Lowers risk of heart disease, stroke, and type 2 diabetes.
• Lowers risk of eight cancers.
• Reduces risk of weight gain.
• Improves bone health.
• Reduces risk of falls.

Emerging research suggests physical activity may also help boost immune function.

For children

Regular physical activity is important for children’s growth and development because it:

• Improves attention and memory.
• Reduces risk of depression.
• Builds strong muscles and endurance.
• Improves blood pressure and aerobic fitness.
• Helps maintain normal blood sugar levels.
• Reduces risk of several chronic diseases, including type 2 diabetes, and obesity.

Saving lives and money

• In the United States, inactivity contributes to 1 in 10 premature deaths.
• About 110,000 deaths could be prevented annually if U.S. adults increased moderate-to-vigorous physical activity by even 10 minutes per day.
• Inadequate levels of aerobic physical activity are associated with $192 billion in annual health care costs.

National security and military readiness

• Both obesity and low levels of physical fitness increase the risk for injury among active duty military personnel.
• In 2018, 71% of US young people were ineligible to join the military.
• Only 2 in 5 young adults are both weight-eligible and active enough for military duty.

Community benefits

For communities, activity-friendly places can:

• Improve safety for people who walk, ride bicycles, and drive.

• Help improve the local economy.
