Relationships between Tsk and thermal comfort for the body (a) and between Tsk and thermal comfort for the lower extremities (b) during the cooling period in the C (closed circle) and N (open circles) groups. A score of −100 indicates cold and a score of 0 indicates not cold at all. The slopes of the relationships between Tsk and thermal comfort in the C group were steeper than those in the N group (P < 0.05)
