A hot summer day. You are on the beach. After you have 'suntanned' enough - you go into the sea and it becomes cold. Absolutely normal - from a hotter place - the hot air on the sand, you co into a colder water.
After you swim enough and it becomes freezing you decide to go back to the beach (where the hot air is). But in spite of becoming hotter, at the beginning it is becomes even colder.
Why is that?
