of course, he’s not socializing with other people, unless they come down and visit, which it doesn’t say they do but might happen occasionally.

That means he’s not being exposed to female pheromones for one thing. also, not all people put out the same chemicals, so that’s another thing he’s missing also in men. Other people’s cortisol and pheromones and other chemical messengers, he’s testing what it’s like to not be exposed to them as well.

he could have cheated as far as not being exposed to the sun. They probably, but I don’t know, we’re smart enough to give him full spectrum light bulbs. Basically, mimic the sunlight. where I live, there’s a brick wall out the window and I don’t get any sunlight, even against the wall, between the start of August and the end of may. The full spectrum lights mean that I don’t go into seasonal affective disorder, I didn’t even notice the difference this year. Previous years, August became very difficult. So if they didn’t do this, that’s how they could have gotten rid of that one factor that makes what he’s doing different from normal life above the water.

A very strict diet, that doesn’t make him like other people. Unless that was his diet before, then he’s testing a change in the diet as well.

Of course, he’s testing what it would be like to live underwater and live on fish, and I guess chickens could live in an underwater shelter providing eggs, so maybe this more mimics what he wants humans to be able to achieve as a result.

His exposure to smog, pfsas, nanoplastics, bacteria and other pathogens, all that has been taken way out of the picture. Whatever he brought with him, that’s the only things he’s been exposed to. He’s not getting new exposures of new chemicals.

He has a limited range of exercises he can do. Since walking is considered to be one of the most helpful, that’s something else that is different from what the average person is living with outside of the water. In other words, what he’s testing is a life underwater with compression rather than merely the difference in health due to compression which is what the article describes, the ambitious undertakinggames to study the physiological and psychological effects a prolonged compression on the human body.

That’s not all they’re testing.

It’s not that they aren’t also testing the body existing in compression. But when they look at any changes in his psych and body, they need to look at the increased amount of fish omega-3 fatty acids compared to the average diet, which helps a number of health issues, the change in exercise, and it sounds like it’s an exercise program beyond what most people have, lack of exposure to people and chemicals that people put out including pheromones, and lack of exposure to a lot of toxins from the environment as well, and other factors that make his isolation and his habits different from the average person.

it sounds like what he’s testing isn’t so much the effects of compression, as the ability of someone to live a healthy life in the underwater environment he hopes that most people will have access to, which is a very worthwhile study, but not quite the same thing as testing how a body responds to compression all by itself.

A note that they need to consider is that natural water usually has minerals in it, and that the reason why some studies show varied effects under what seems to be the same circumstances is whether the water in that region is hard or soft, or municipal water that may be completely deficient in nutrients that the body expects in water, so they also need to consider what’s form of water he is drinking while he is there for comparison purposes.
