Which technique demonstrates passive relaxation?

Passive relaxation techniques focus on calming the mind and body without requiring significant physical effort or active engagement. Slow abdominal breathing exercises are a prime example, as they encourage deep, rhythmic breathing that can lead to a state of relaxation and reduced tension. This technique does not demand active movement or strenuous effort, allowing individuals to simply focus on their breath and gradually lower their physiological arousal.

In contrast, the other options involve varying levels of physical activity or mental engagement. Yoga poses often require physical effort and concentration, making them more active than passive. Walking meditation, while focused on mindfulness, also involves physical movement and the engagement of the body in walking. Guided visualization can be relaxing and require minimal movement, but it still necessitates mental engagement to imagine scenarios or imagery effectively. The direct and focused breathing of slow abdominal exercises exemplifies a passive approach to relaxation.
