As others have said, in this thread, there are a lot of mixed issues in this article.
Living a nomad/traveling lifestyle =! remote work. Loads of people remote-work from home, but change nothing else in their lifestyle.
I've been working remotely my entire life. 30+ years now. One thing that is key, is looking at the blue sky. Being outside occasionally.
You will note that the article talks about work/life balance, about working a lot, working long hours. And after months and months, become more and more depressed.
What I suspect is happening is, winter! Shorter days! With shorter days, it is harder and harder to find sunlight when you just happen to wander outside. In the summer, at least where I am, daylight lives from 4am to 10pm. I doesn't matter when I wake up, or when I go to sleep.. if I wander out just once, there's almost always light.
Further, there's a much better chance of good weather. In the winter, if it isn't night, it's often cloudy, and therefore darker.
Unless you work away from all windows, this affects the type of light, even when working inside.
On top of all that, in the winter it is more often unpleasant. You think with glee, it's cool/cold, raining/snowing, and I work remote! I don't have to go out into that! Yet, this is a trap, for going out in that is key to your health... just for the light!
My point in all of the above is -- when you work on site, you have to go outside, and transit outside, to and from work. This gets in that vital light, even often in the winter.
It's about the light, it's about blue light from a blue sky, it's about being outside.
That's what 30+ years of remote work has taught me.
