松 (Relaxation) refers to a state of mental and physical ease, where tension is reduced, and a sense of calm is achieved. It is often associated with practices such as meditation, yoga, and deep breathing, which help individuals release stress and promote well-being. In many cultures, including Japanese and Chinese, relaxation techniques are integral to maintaining a balanced lifestyle. Activities like spending time in nature, enjoying a warm bath, or engaging in hobbies can also contribute to relaxation, allowing individuals to recharge and improve their overall health.
