Where were you taught this? It’s pretty much incorrect.

It is true that particles at higher temperatures have higher kinetic energies. But their velocities are so far away from light speed (usually) that relativistic effects like time dilation are entirely irrelevant.

For reference, the surface of Pluto is about 40K. Some of the other dwarf planets a little further out are in the 21K range. Liquid hydrogen (used in many rockets) is 20K.

69K is slightly warmed than liquid nitrogen (63K), and that is incredibly commonly used all over the world. And warmer than Pluto ;)
