Cold is a density which removes heat, which slows things down.
This can be thoughts (cold air), emotions (cold water), or physical (cold ground).
In cold, we have to be more active to stay alive, the density of cold is like an entropy which makes it hard to get momentum.
A person who is cold is called “unfeeling.” But usually this coldness is a form of protection, an armour against getting hurt.
A cold place is considered inhospitable – or refreshing. Sometimes preparation is the key to surviving cold.
