During summers, Pakistanis are especially vulnerable to hot weather hazards, most of the cities of Pakistan can be as much as 10 to 15 degree warmer than surrounding areas because the cities infra structure largely made up of asphalt, concrete and metal that traps the heat. Keeping cool indoor when it is hot outdoor is a problem. The sun beating down on our homes causes indoor temperature to rise to uncomfortable levels.
