Wow, the pictures with the frozen water look like a drawing rather than reality. Stunning!

As for the anxiety and breathing importance - I'm in the same team, unfortunately. Been fighting with depression and anxiety for the last 4 years and one of the most important things that make me feel alive is going to nature or just getting some fresh air in the morning. Some cold air. To let nature wake me up. And I'm lucky enough to live in a place pretty close to the mountains where the pollution is pretty little.
