Last week, we took you through all the ways that cold can harm us and the harrowing history of humans perishing at its icy hands. Ending the story there would be skipping over the parts where cold gets to play the hero, rather than the villain. In the second installment of this frosty miniseries, we explore the situations in which we might use cold to protect us and how it actually works. We also delve into the surprisingly long (and unsurprisingly grim) history of therapeutic hypothermia, a journey that wouldn’t be complete without a debate over sea cloaks, a reconsideration of the plot of Titanic, and a brief jaunt into cryonics.

| 0:00.0 | This is exactly right. |
| 0:03.0 | In 1967, I was treated with hypothermia by immersion in ice-cold water as part of a local study, |
| 0:12.0 | and then developed subcutaneous fat necrosis. |
| 0:15.0 | Both myself and one other case were reported by the neonatal team who looked after me |
| 0:20.0 | to have had otherwise |
| 0:21.1 | favorable short-term outcomes, but on the basis of this complication, these early studies of hypothermia |
| 0:26.8 | were stopped. I was born weighing 3,970 grams at full term after an uncomplicated pregnancy, |
| 0:34.1 | labor, and delivery. As reported, at one minute after birth, I became apnic and did not |
| 0:40.1 | respond to resuscitation. After five minutes, I was placed in an ice water bath. My breathing was |
| 0:45.5 | reported to recover after 28 minutes of hypothermia. At 45 minutes of life, my capillary pH was 6.9, |
| 0:52.6 | but recovered steadily, and I was discharged at day three. |
| 0:56.7 | Subcutaneous fat necrosis developed between two and four weeks of age. The calcium |
| 1:01.1 | deposits were largely cleared by six months. My serum calcium remained normal, and my weight |
| 1:06.1 | gain and development were considered appropriate at that age, but no further follow-up was |
| 1:10.3 | reported. Fifty-three years after these events, I have had a very normal life. |
| 1:14.6 | Although my mother teased me about my skin in childhood, |
| 1:17.6 | I never had any apparent skin problems as a child or later. |
| 1:20.6 | I was a keen sportsman at school. |
| 1:22.6 | My handwriting was never a strength, and so I taught myself to touch type, |
| 1:26.6 | which turned out to be an advantage in the computer age. |
| 1:29.6 | At the same time, it is interesting to note that I can easily thread a needle. |
| 1:33.8 | Academically, I did very well throughout school and university. |
