“The air temperature that night probably was not lower than 38° or 40° Fahr. […] we were rendered uncomfortable in our cramped sleeping quarters by the unaccustomed warmth. Our feelings towards our neighbours underwent a change. When the temperature was below 20° Fahr, we could not get too close to one another—every man wanted to cuddle against his neighbour; but let the temperature rise a few degrees and the warmth of another man’s body ceased to be a blessing.”

— Ernest Shackleton, South
