Empty Ice-Cube Trays and Shrieks: Cold-Therapy Comes to the Family Bathtub

Justin Mullner, a 40-year-old doctor, emptied his family’s two ice makers into the bathtub at his home in Orlando, Fla., added cold water, checked the temperature with a thermometer, stripped down to his swim trunks and hopped in. 

His wife, Blair Heinke, heard him screaming less than a minute later. “I thought he was a wimp,” said Dr. Heinke, a former marathoner. “The ice cubes all melted. That’s not cold.”
