Detailed explanation-1: -Protecting astronauts from the extreme temperatures of space while they explore the Moon or repair the exterior of the International Space Station requires a suit that performs well in temperatures ranging from 249 °F to-245 °F.
Detailed explanation-2: -To cope with the extremes of temperature, most space suits are heavily insulated with layers of fabric (Neoprene, Gore-Tex, Dacron) and covered with reflective outer layers (Mylar or white fabric) to reflect sunlight. The astronaut produces heat from his/her body, especially when doing strenuous activities.
Detailed explanation-3: -Spacesuits are specially designed to protect astronauts from the cold, radiation and low pressure in space. They also provide air to breathe. Wearing a spacesuit allows an astronaut to survive and work in space.
Detailed explanation-4: -Because a spacesuit is sealed, it cannot dissipate the astronaut’s body heat, and the inside gets very hot. Without a cooling mechanism, the astronaut’s body temperature can keep rising, and that would eventually turn deadly.
