What is a physiological effect of regular yoga practice on the body?

Regular yoga practice has been shown to have a significant impact on the body, particularly in reducing stress levels through the modulation of cortisol, often referred to as the stress hormone. High levels of cortisol can lead to negative effects such as increased anxiety and various health issues, whereas a consistent yoga practice promotes relaxation, encourages mindfulness, and helps to balance hormone levels, contributing to an overall sense of well-being.

Research indicates that engaging in yoga can lead to lower cortisol outcomes, fostering a calmer and more balanced physiological state. This reduction in cortisol is directly linked to the benefits of yoga, such as enhancing emotional resilience, promoting a sense of peace, and improving the body's stress response.

In contrast, the other options suggest physiological effects that are not aligned with the typical outcomes of yoga practice. Increased heart rate, heightened cortisol levels, and improved circulation only during intense workouts do not capture the essence of what regular yoga is designed to achieve. Instead, yoga is more about fostering tranquility and enhancing bodily functions in a holistic manner.
