Which of the following behaviors could improve healthy life expectancy?

Engagement in physical activities plays a significant role in improving healthy life expectancy. Regular physical activity helps to maintain a healthy weight, strengthens the cardiovascular system, and reduces the risk of chronic diseases such as diabetes, heart disease, and certain cancers. Additionally, being physically active enhances mental health by reducing symptoms of depression and anxiety. It also promotes better sleep, boosts the immune system, and can lead to a longer, healthier life.

Conversely, behaviors such as regular consumption of sugary drinks, high levels of stress, and a sedentary lifestyle typically have negative effects on health. Sugary drinks contribute to weight gain and increase the risk of metabolic syndrome, while high stress can lead to various health issues, including hypertension and heart disease. A sedentary lifestyle is associated with decreased physical fitness and increased risk of several health problems as well. Therefore, engaging in physical activities stands out as a key behavior in enhancing healthy life expectancy.
