Which of the following is a benefit of maintaining health and well-being?

Maintaining health and well-being plays a crucial role in improving heart function. Engaging in regular physical activity, following a balanced diet, and managing stress contribute to cardiovascular health by strengthening the heart muscle and improving circulation. This leads to a more efficient pumping of blood throughout the body, which enhances overall cardiovascular fitness. Additionally, good heart function is essential for delivering oxygen and nutrients to tissues, supporting physical performance and overall health.

The other options highlight consequences that would not align with the positive outcomes associated with maintaining health and well-being. For instance, increasing stress levels and decreasing energy efficiency contradict the benefits of health maintenance, which typically involve stress reduction and increased energy levels. Furthermore, health and well-being should enable individuals to participate fully in everyday activities rather than restrict them.
