(CNN)It was negative 13 degrees Celsius (8.6 degrees Fahrenheit) when Lorelou Desjardins took a break from her workday to take a walk on the frozen lake near her home in Oslo, Norway. She was accompanied by her husband, who had recently been on four months of paternity leave, and their infant son.
How the Nordic 'friluftsliv' lifestyle can fight wintertime and pandemic blues
Not only was she encouraged by her employer to take this walk — she is paid one hour per week to exercise or spend time outdoors. It's one of the several times she goes outdoors during the workday.
Other times are to put her 1-year-old out for a nap, wrapped up in blankets outdoors, like they do with him and the other babies in day care, or by taking a walk in the forest whenever she has a meeting over the phone with a colleague, which her workplace encourages her to do.
That's thanks to friluftsliv (pronounced FREE'-loofts-liv), a Norwegian custom that means living "life in fresh air," or more simply, spending time outdoors and being active.
"It's life in fresh air, which in English, you could say is an outdoorsy life," she said. "But it's actually more than that. It's not just about being outdoorsy, it's about taking advantage of every moment you have in nature."
Friluftsliv is not a concept the French-born Desjardins has spent her life living. She moved from France to Norway in 2010. However, she said she's much less stressed ever since making the move. She even did a TED Talk on the topic just over three years ago.
"When I moved to Norway, I was kind of a workaholic. And so, coming here and having my boss tap my shoulder at 5 or 6 p.m. and tell me, 'What are you still doing at work? Go outside, it is nice weather," she said. "It's kind of this spirit of 'OK, work is great, but we have a life out there, that life involves being outside.'"
