As an expert in astrophysics, I can explain that while space is extremely cold, a person would not instantly freeze. The human body has a certain amount of internal heat and, in the vacuum of space, there is no mechanism like convection to quickly transfer that heat away. Heat transfer in space primarily occurs through radiation, which is much slower than the convection that occurs on Earth. So, while the body would eventually cool down, the process would not be instantaneous.

Though space is typically very cold -- most floating objects have a surface temperature of -454.8 degrees Fahrenheit -- a person would not instantly freeze because heat does not transfer away from the body very quickly. On earth, heat can be transferred via convection, but outer space is mostly nothingness.
