A ‘Corpsicle’ Came Back to Life on ‘True Detective.’ Is That Possible?

The men lay frozen naked in a ghoulish pile, with mouths agape and eyes glazed over, their hair encrusted with ice and snow. They were all dead — or so the investigators on the HBO series “True Detective: Night Country” thought.

Frozen bodies are a familiar problem in this fictional Alaska town near the Arctic Circle, but this giant “corpsicle” is unusual. And so is what happens at the end of the episode, which aired last Sunday: one of the men wakes up when his arm is accidentally snapped off by an officer.

The resurrection has sparked grisly speculation among some fans: How can a person be living, a viewer on Reddit asked, if that person’s limbs are so frozen? “They could have been flash frozen in a moment of terror” at the moment of their deaths, another speculated. Many were skeptical that the human body could survive such an ordeal and wondered if the show was straying into the supernatural.

Doctors say that it is impossible for a completely frozen person to make a recovery. But it is possible for someone who appears frozen — limbs stiff, skin cold and hard, and without a pulse or breath — to be resuscitated, depending on how long the person has been out in the cold.

“If all the tissue in your body is ice, or has ice in it, then you’re not coming back,” said Ken Zafren, a physician and a professor of emergency medicine at Stanford University, who also works in Alaska. But, he added, “I’ve seen plenty of cases in which the person really looked dead, and could come back.”

During hypothermia, an adult’s body temperature can cool well below the normal average of 98.6 degrees, Dr. Zafren said. A person’s pulse and breathing slow significantly, reducing the body’s need for oxygen. Eventually, the person may go into cardiac arrest, stopping the pulse and breathing altogether. But because the brain is cold, the lack of oxygen takes longer to cause damage, he said.
