Saudi Arabia is applying a heat-reflective coating in Mina that may lower road t

Saudi Arabian government to enhance the comfort and safety of pilgrims during Hajj. The use of a heat-blocking coating in Mina, which can significantly lower road temperatures by 15°C to 20°C, is particularly beneficial in such a hot environment where temperatures often soar to extreme levels.

With road temperatures in Makkah reaching as high as 70°C, this technology can make a substantial difference in the overall experience of the Hajj pilgrims, especially considering they spend four days in the area.

The heat-blocking coating is likely to be made of a material that reflects solar radiation, which is the primary source of heat. This can include substances with high albedo or reflectivity, such as certain types of asphalt or paint. By reducing the absorbed heat, the coating helps to maintain a more bearable surface temperature on the roads. Additionally, the design that allows for the scientific discharge of heat at night is crucial as it provides relief during the cooler hours when the body naturally attempts to recover from the day's heat stress.

This initiative not only addresses immediate concerns for the comfort and health of the pilgrims but also underscores the importance of environmental considerations in urban planning and infrastructure development. The reduction in surface temperatures can contribute to the mitigation of the urban heat island effect, which is a significant issue in densely populated cities like Makkah. Moreover, it can also lead to lower energy consumption for air conditioning in nearby buildings and reduce the overall carbon footprint.

The implementation of such a coating is a testament to the advancements in technology and the commitment of the Saudi authorities to ensuring that the Hajj experience is as comfortable and safe as possible for the millions of Muslims who undertake this religious journey each year. This innovation will undoubtedly be a welcome change for the pilgrims, providing them with a more comfortable walking and resting surface during their stay in Mina.
