The Benefits of Reducing Heat Stress on the Environment

As an important element of the human world, the Earth is now moving from most country planets to most urban planets. From 2000 to 2030, urbanized areas will almost triple (Seto et al., 2012). The use of dark building materials such as asphalt and concrete has reduced the albedo in urban areas rather than the natural environment (Rosenzweig et al., 2011), promoting regional and global warming. Instead, the increase in urban albedo supports climate stabilization efforts (REF). Here we looked at the potential impact of albedo on temporary changes in radiation compulsion in a representative group of European cities.

• In urban environments, more thermal stress may occur. Warm summer temperatures and more extreme heat events will increase the possibility of thermal related diseases and deaths associated with cardiovascular disease, respiratory disease, cerebrovascular disease (such as stroke). A warm and dry summer can also increase the amount of water and energy required for the summer, potentially lowering the life and performance of the asset. • Increase the risk of landslides. As the amount of rain in winter increases, the saturation of the ground rises, the risk of landslides increases, leaks around the retaining walls, structures such as underground vaults, and collapsed trees. Exposure to higher groundwater and more moisture also increases corrosion and shortens asset lifetime

Man lived in a hot environment for a long time, and several physiological mechanisms were developed to cope with thermal stress. We are constantly exposed to two kinds of thermal stress: environmental and metabolism. Heat can be obtained from the environment via radiation, convection and conduction, and heat generated during metabolic activity exacerbated by fatigue. The heat obtained from these heat sources must be balanced by the heat loss to the environment and the evaporative cooling mechanism (Hanna and Brown). Failure of these cooling mechanisms can lead to serious conditions that can cause heat stroke, serious damage to the central nervous system (Bouchama and Knochel 2002). Excessive dependence on evaporative cooling can lead to another debilitating condition, dehydration. The hot desert environment as seen in North Africa and the Arabian Peninsula is a perfect storm for human's heat resistance.

Several theories are used to identify and describe thermal stress. Heat stress can be measured. In other words, work and play in hot places may put pressure on the body's cooling system. When combined with other stress and heat, such as physical labor, fluid loss, fatigue, or other conditions, it can lead to heat related disorders, disability, even death. Even if you are a young and strong man, this can happen to anyone. In particular, thermal stress is a serious problem in industrial work environments. In occupations where clothes with insufficient ventilation pair with high temperature and high humidity, thermal stress is a threat to workers. Workers who must face extreme heat are potentially dangerous. According to Stelmakowich, A (2001, p.14), Kim Douglas Warner works near Bally's Oven in Ontario. He collapsed after working for a long time at a bakery, and when he was taken to the hospital he was declared dead.
