A Swedish man was dug out alive after being snowed in to his car on a forest track for two months with no food, police and local media have reported.

The 45-year-old from southern Sweden was found on Friday, emaciated and too weak to utter more than a few words.

He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a car wreck until they dug their way to a window and saw movement inside.

The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19th.

"Just incredible that he's alive considering that he had no food, but also since it's been really cold for some time after Christmas," a rescue team member told regional daily Vasterbottens-Kuriren.

Ebbe Nyberg, duty officer at the Umea police, said police saw no reason to doubt that the man had been stuck in the car for a very long time.

"We would not make something like this up. The rescue services were on site too and saw the same as us," he told the newspaper.

Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.

Doctors at the hospital said humans would normally be able to survive for about four weeks without food. Besides eating snow, the man probably survived by going into a dormant-like state, physician Stefan Branth told Vasterbottens-Kuriren.

"A bit like a bear that hibernates. Humans can do that," he said. "He probably had a body temperature of around 31 degrees which the body adjusted to. Due to the low temperature, not much energy was used up."

Why the man ended up under the snow in the forest remains unknown, police said.
