Study on the effects of partial cooling for physiological responses relief in duty booth under high temperature weather

摘要

High temperature and hot sun environments are prevalent in many situations. The extreme environments have put forward a severe challenge to the health and safety of the outdoor workers. However, people in duty booth still stick to their post to guarantee social normal production and living activities. In this paper, security guards and tower crane workers are selected as research objects. In order to study the effects of partial cooling, the physiological responses in three conditions including head cooling, limbs cooling and no cooling are compared. The research shows that limbs cooling and head cooling can reduce the body's skin temperature, then relieve the sweat rate and improve the body's thermal sensation. The results of the study can provide an important method foundation for the protection of the worker's heath under the outdoor high temperature and sun exposure environment.
