Shower your way toward winter toughness
Time magazine this week has an intriguing article on ways to acclimate your body to the arrival of cold weather.

They had mostly stopped shivering after two weeks. (It didn't say what happens to naked women, but presumably it works for them, too.) Another study in 2014 persuaded another group of healthy men to spend up to three hours a day sitting in baths filled with 57 degree water.
