Which technique can help reduce the physiological effects of stress?

Progressive muscle relaxation is an effective technique for reducing the physiological effects of stress because it involves systematically tensing and then relaxing different muscle groups throughout the body. This practice not only helps individuals become more aware of their body tension but also facilitates a release of physical stress and promotes relaxation. By engaging in this technique, individuals can counteract the physiological responses associated with stress, such as increased heart rate and muscle tightness, leading to an overall improvement in their sense of well-being.

While deep breathing and yoga are also beneficial in managing stress, they are not the sole focus of the correct option here. Deep breathing primarily emphasizes calming the breath to mitigate stress responses; however, it lacks the specific muscle engagement component that progressive muscle relaxation offers. Similarly, yoga encompasses a broader range of practices, including posture (asanas), breath control (pranayama), and meditation, making it a multifaceted approach rather than a singular technique designed specifically to address muscle tension. Progressive muscle relaxation uniquely targets the connection between muscle tension and stress relief, making it particularly effective.
