Abstract
Human body’s endurance for high temperature or low temperature is limited. The change of environment temperature can directly affect the body surface temperature, and then affect the blood circulation system, thereby affecting the efficiency and safety of human. There are only a few reports about the relationship between temperature and blood circulation system so far. In order to explore the specific relations, we established a controllable temperature cabin. Based on the cabin, 15 healthy young male subjects’ blood flow velocity, heart rate and blood pressure were tested. The results show that the blood flow velocity at carotid artery decreases when the environment temperature increases from 15 to 25 °C, and then increases along the environment temperature increases from 25 to 40 °C. Heart rate and blood pressure presents the similar trend as the blood flow velocity along the variation of environment temperature.
