@Neil_J_Thomson asked the Naked Scientists:


It was 20 in the shade yesterday - nice and warm. So why does the swimming pool feel cold at 25 or even higher?

Neil (Kent)

What do you think?

When you "feel cold" it is a relative sensation, i.e. it tells you not what temperature you are, but whether you are loosing heat.

Your body is at 37.5C and air is an insulator, but water conducts heat very well.
Note how it feels cooler in the wind.
