Yoga Mat helps practitioners to keep their hold strong on the surface due to its anti-slipping nature. It also provides a sort of insulation between the human body and the ground. This prevents any loss of heat, charge or energy from the body to the ground and thereby provides a thermo-insulation. For these reasons, Yoga Mat is considered necessary for every yoga practitioner. Ideally it would be best to have mat which are breathable and absorbs sweat.
