Why does water from a shower the same temperature as the room feel colder?
In: Physics
The air in the room is actually quite cold, but that’s OK since air has so little density and therefore isn’t very good at removing heat from your body. Sure, the air takes a little heat from you, but it’s roughly the same amount as your body is producing so your body and skin temperature is comfortably stable.
Water, on the other hand, has a high density and is really good at taking heat from you. Room temperature water flowing over your skin will take heat away from your skin faster than it’s being replaced by your body, so your skin temperature lowers and you feel that cooling/chilling sensation.
