May I just ask, out of pure curiosity, who is this person to you? I mean to understand why you care enough to conduct any kind of tests or whatever.
If they’re bad company, simply avoid and disengage. Why waste energy and time in fragile attempts at proving something that isn’t exactly provable with ordinary means? Like why even think about all this in the first place?
If it’s personal in that you feel slighted by them, I’d still recommend not engaging in weird tests or similar behavior. You’ll ultimately learn nothing useful and will have spent your time and energy for basically nothing. I get that you might be very driven by whatever the reason is, but maybe if you take a step back, breathe a moment, you might be able to re-evaluate whether this is actually important and worth your effort.
You only have the time you have, and the energy you have. It’s very limited. I just wanted to step in and suggest you might spend it doing something pleasing and positive instead. You’ll be better off, I ensure you.







Probably worth mentioning, that the benefits of this can be reaped in part just by being and walking in nature every day. Especially on the mental health side, in some places of the world, I think it’s a general concept called “forest bathing” or similar.
I’ve never done a hike longer than 100km, which means I’ve never been on the trail for more than a few days at a time.
However, I’ve noticed the same effects ever since I started doing that more frequently. I’m much less prone to falling properly sick than any of my friends or family, whenever my partner falls ill, I typically go through a mild similar thing in a few days time, but often survive without even fever, when they can be bedridden for weeks, even. I might get some signs of a flu or whatever, but so much milder. It’s not unusual that I just entirely skip being sick at all, even mild symptoms, even if my entire household is struggling in bed with fever. And I tend to be the caretaker then, so ample opportunity for the bugs to pass on to me, constantly.
And every time I realize I’m falling unusually sick, I realize that it’s been some months since my last hike.
And if I just keep doing a hike or two biannually and otherwise visit the forests or the lakes or whatever at least once a week, even if just briefly due to stress and work and all, I am so much less prone to proper sickness, but having any sickness at all in general too!
So this is mostly for those who read the OP I’m responding to and thinking, it’d be nice to afford 6 months of a vacation — you need not! It works, even if this is just an anecdote, with fewer efforts and much more casual execution too! And it has been studied a lot, although take it with a grain of salt because I haven’t stored any of the studies/papers of the abstracts I’ve read just passing by thanks to my adhd curiousness.
I think the consensus is, nevertheless, that there are provable, observable benefits of being in nature, even if just a bit at a time, even if not all that frequently. But I’m not a researcher or work in these kinds of fields, so just be wary that I might be overselling or even misrepresenting it. But I feel fairly confident in saying so.
