"Their passion for nature cuts to the heart of what Scandinavians call friluftsliv (pronounced free-loofts-liv)."

"The expression literally translates as 'open-air living' and was popularised in the 1850s by the Norwegian playwright and poet, Henrik Ibsen, who used the term to describe the value of spending time in remote locations for spiritual and physical wellbeing.... Today, the phrase is used more broadly by Swedes, Norwegians and Danes to explain anything from lunchtime runs in the forest, to commuting by bike (or on cross-country skis when the snow falls) to joining friends at a lakeside sauna (often followed by a chilly dip in the water) or simply relaxing in a mountain hut. The concept is also linked closely to allmansrätten, the right to roam. Scandinavian countries all have similar laws which allow people to walk or camp practically anywhere, as long as they show respect for the surrounding nature, wildlife and locals....  Swedish data confirm that the amount of time young people are active outdoors has dipped slightly over the past three decades, with around 25% now spending time in the countryside or forest at least once a week, compared to 29% in the early 1980s."

From "Friluftsliv: The Nordic concept of getting outdoors" (BBC). That's a 2017 article. I got there after googling "friluftsliv," which I encountered in a new article, "One Tank Getaway: Late winter in Door County offers great food, welcome respite" (On Milwaukee).
