Final answer:
If you meet the guideline of 150 minutes of moderate-intensity exercise a week, you can lower your risk of mortality significantly and gain almost four years of life. This exercise regimen also contributes to an array of health benefits, including improved cardiovascular health and fitness, bone density, and cognitive function.
Step-by-step explanation:
According to the U.S. Department of Health and Human Services (HHS) guidelines, engaging in at least 150 minutes of moderate-intensity exercise per week can significantly lower your risk of mortality. The HHS recommends a range of 150 to 300 minutes of moderate-intensity aerobic activity weekly for substantial health benefits, which translates to a lower risk of conditions such as heart disease, stroke, and type 2 diabetes, among others. When people exercise at 100 percent of the HHS guidelines, they gain an average of almost four years of life. This is indicative of the strong positive correlation between regular aerobic physical activity and extended life expectancy. Additionally, diverse health benefits such as improved cardiovascular and muscular fitness, bone density, cognitive function, and psychological well-being are associated with consistent moderate exercise.
