Study on the accumulated thermal load of walking pedestrians (part 1): Simultaneous measurements of physical environments and physiological responses during standing and walking outdoors in summer

To analyze the human physiological responses in outdoor spaces during summer, physical environments and human physiological responses were measured simultaneously. The increase in skin temperature of lower arm and back of hand during walking was smaller than that measured during standing. In high MRT environment, the increase in core temperature during walking was smaller than that measured during standing. This is related to an increase in heat loss from the body due to the increase in relative air velocity exposed on the body sweating and heat transportation from core to skin due to the increased blood flow rate during walking.
