People often set temperature records when they are sick.
But the Guinness Book of Records has an interesting record – the lowest body temperature ever recorded in a human.
The unwitting record holder was a 27-month-old baby from Poland.
One morning he left his grandmother's house barefoot.
At this time of year the air temperature was 7 degrees below zero.
The child soon reached a stream and lost consciousness, lying on the street for at least three hours before rescuers found him.
The child was urgently sent to the hospital.
Doctors managed to resuscitate the boy in the ambulance.
The baby's body temperature was only 11.8 degrees.
Within two weeks the boy had recovered.
Before this, medicine knew of only one case of a person cooling to such levels.
In 1955, a 51-year-old patient was deliberately cooled to 9 degrees to treat ovarian cancer.
The patient survived the operation and no negative consequences were reported.
