The towel spread on a yoga mat is commonly referred to as a yoga towel or yoga mat towel. This towel is specifically designed as an auxiliary item to be placed on a yoga mat during yoga practice, and has the functions of sweat absorption, anti slip, and maintaining cleanliness.

　　Yoga towels are usually made of natural fiber materials with strong water absorption, such as cotton or microfiber materials. This material can effectively absorb sweat and keep yoga practice dry and comfortable. At the same time, the surface of yoga towels is usually designed with anti slip textures or coatings, which can provide better grip and avoid sliding and falling due to sweat during yoga practice.

　　In addition to being used on a yoga mat during yoga practice, a yoga towel can also be used as a body cover to wipe sweat or cover the body to keep warm after practice. Therefore, it plays multiple roles in yoga practice, serving as both a functional auxiliary tool and a comfortable accessory to enhance the practice experience.

　　In general, towels laid on yoga mats are commonly referred to as yoga towels or yoga mat towels, and are common auxiliary items during yoga practice. They have functions such as sweat absorption, anti slip, and maintaining cleanliness, providing a more comfortable practice environment for yoga enthusiasts.
