ELI5: Why is it so difficult to tell if clothes are damp or just cold?
gpt
It helps to first realize that there isn't really a "cold." When you feel something, like a metal door knob, that appears cold, it's actually because your body is warmer than the knob, and what you feel is your hand actually heating the knob up! The knob robs heat from you. 

Clothing can also be at a lower temperature than your hand (like if you've left it in your dryer in the basement overnight), and you'll feel that same feeling; your hand heating up the clothing. 

Water is really good at robbing heat from you. A warm pool will still feel cold when you first get in, and your sweat robs the heat from your skin when you're warm. We have deep memories that water having that "chilly" feeling. 

Sometimes, your brain just gets confused whether clothing is cold or whether it has a small amount of water held in it that's robbing the heat from your hand.

Hope that helped.
