It's been well established that access to plants and pets is good for general health.
I think there may be several ways this is possible. One is that even a lawn or other area like this stays about 30 degrees cooler in the heat and the small animals flourish there.
Trees may help in other ways, with shade in the heat and by moisture, protection from the rain as well as in the winter evergreen trees even protect from the snow. Perhaps most important, green spaces give more oxygen..
Since the grass doesn't give much shade or protection from the snow, one thing we might predict is how the health benefits of living near trees are greater than than for those who just live near lawns.
And while in the winter it's cold even without the trees, and while it might be colder near the trees because they're evergreen and they give shade, in general there might be a slight effect of the tree to improve the health of a person in winter because they also give oxygen and they even protect from the snow at least if beneath them.
Since I walk a lot and I want to stay fit there is a line of trees up a hill near where I hill where they planted them, And so on the summer I walk in that line of the edge the shade all the way up and down two or three times for a cardio boost, sort of recycling the shade and this is a more comfortable in the heat and this is what I think may have been going on when we were living in the tropics.. Perhaps the rainforest wasn't so miserable because it's constantly raining, and when you're moist you feel five times cooler than when you're dry and because we were constantly in and out of the shade.
Another aspect of green spaces may be about how as we looked around in evolution all the time we were seeing all kinds of plants around us except if we lived in the desert.
If, as has been noted, heredity is stored environment, the sight of plants themselves might have a strong influence on how we think and feel. Another influence may be by the wildlife that may live in the green space which gives another element of reality to the viewer.
Therefore those who mostly live near concrete may show the smallest positive influence of green spaces like lawns, because they neither see the plants or animals as much, nor do they get the oxygen or the cooling in the heat.
Those who live near lawns but no trees are getting some visual energy, perhaps even by the wavelength of the greenness of the herbs to their vision, oxygen, cooling, moisture, and the possible influence of some types of wildlife hey it's Saturday night! throw a party!
The sounds of wildlife may also have influence on health because if there is no sound in the room where you live it's been found that your brain doesn't have a loop of reaction back and forth to constantly refine the brain and sensation by these small sounds.
The sounds of animals may be more valuable than just sounds around the house to our health (What's that RV doing in the living room!) in this respect because they create more dynamic tension and may exercise your brain more.
Those who live near green spaces with both lawns and trees may have more of these influences, and if some of the plants are evergreen they may even get another advantage in the winter by shielding from the snow.
Even so people who have evergreen trees giving more shade to their house in the winter might not have it as good as people with deciduous trees shading their house in the summer even while deciduous trees wouldn't add shade in the winter to cause lower temperatures which you wouldn't want.
On the other hand Evergreen trees would give oxygen year round unlike deciduous trees.
It's been found the plants grow faster when they give sound like classical music or mostly any vibration. So it might make us also do well if we have these same vibrations.. Even the sound of the wind through the trees may be good for our health and when we emerge out into the sunshine the sight of the clouds and the blue sky may be a boost to our health also as well as just as in evolution we can meet people there we see more often..
These are some of the reasons, not just the green spaces being outdoors is good for health.
It would seem that plants also filter out pollution so small oxygen filters that would go in the nose powered by nuclear batteries like the chinese have invented that would last 100 years and with a special oxygen compound that stores a large amount of oxygen may be of use.
This might also be a good way to defend against pollution for living in the city much more cheaply than a gas mask to wear is just for the rich! Just small fans in your nose that make you feel a lot better without pollution and to reduce covid or bird flu events.
This could be useful for doctors as they treat health issues and also about antibiotic resistance which may become worse than covid according to some science sites. This might be useful for farmers and for the cows themselves to wear these filters and for people who live near the beach which is 75% of the people ..3/4 of the bacteria in the air at the shore are bad bacteria caused by people. Evolution may never have been like this And now you can see why the real estate value of property with a view of the water is up 100%, well, somewhat!
All these aspects, oxygen, moisture, shade from the heat, reduction of pollution, the visual aspect of both the plants and the animals, natural sounds of animals to energize the brain that often are around green spaces, all these are measurable by experiment to find out which ones are the most valuable. We might imagine the visual aspects could all be simulated by virtual reality for the benefits of green spaces without living near them like for those who can't afford access, and oxygen might be used with this VR simulation, as well as the sounds of wildlife. The main part of the simulation about staying cool in the heat might be allowed by air conditioning, alternating with lots of heat to simulate going out into the sunshine as well as with sun lamps since it's become apparent that all the wonders of vitamin D actually have turned out to be caused by sunshine on skin..
Other science has shown how alternating between hot and cool is good for your immune system.. of course because most people lived by the ocean In evolution as they do now before the invention of fire "When will they invent fire?" I was attributing this health value of alternating hot and cold to how we would just go in and out of the water but I also realized that in the tropics we were also going in and out of the shade of the plants..
This is why for an indoor simulation of a green space as I say we might want to alternate heaters with air conditioners for the most healthy event, or any rate to prove this. If some of these influences are more powerful than others it might be a lot easier to get the result than with the 100% VR simulation. And It seems possible some of these isolated influences could be multiplied up more than natural or with alternation etc. for an even more valuable boost to health.
