Which health outcome is commonly associated with enhanced activity of the parasympathetic system?

Enhanced activity of the parasympathetic system is commonly linked to increased relaxation. The parasympathetic nervous system, often referred to as the "rest and digest" system, plays a crucial role in promoting a state of calm and reducing stress levels in the body. When this system is activated, physiological responses include lowered heart rate, reduced blood pressure, and increased digestive activity, all of which contribute to a state of relaxation.

This relaxation response is essential for recovery and restoration of the body. It counteracts the effects of the sympathetic nervous system, which is responsible for the "fight or flight" response characterized by heightened alertness and stress. Through practices such as deep breathing, meditation, and biofeedback, individuals can enhance parasympathetic activity, leading to improved health outcomes such as reduced anxiety, improved immune function, and overall well-being.

In contrast, the other choices reflect outcomes that are typically associated with reduced parasympathetic activity or heightened sympathetic activity. For instance, higher anxiety levels and higher blood pressure are symptoms of stress responses, while decreased immune response can result from chronic stress, which suppresses the parasympathetic system's restorative functions.
