eli5 – How is space cold?

How is space “cold” when it’s a vacuum? Isn’t temperature transferred between mass? If anything, shouldn’t you overheat when in a vacuum, because your body generates heat?

As Neil deGrasse Tyson said, space isn’t cold, since there is no mass to transfer the heat energy to. However, it would feel slightly cold to the body, since your body would slowly radiate heat away. There are, however, areas of space filled with gas coulds that would feel as cold as that guy said in the infamous tweet that just popped up. He did a google search and didn’t check the source.
