ELI5: Why do things hurt more when you are cold?
gpt
The receptors that sense pain are the same ones that sense cold. Which is why when you are in pain, a cold compress usually soothes it. The pain/cold receptors, instead of saying "pain, pain, pain, pain," have to transmit both signals "pain, cold, pain, cold" cutting down on the pain signals sent.

Ironically, if you are cold and something painful happens, the receptors switch to pain, but in the process of switching from cold to pain signals, transmit some of the cold signals as pain signals, thus transmitting more pain than there actually is.
