Vertigo, aka height intolerance, and other terms.

Yes it’s phycological. I’ve got a scaffolding friend who seems to have no fever of heights (he’s worked on some of the largest builds in the world and specialist in scaffolding that hangs under buildings? Do t know the word only seen the pics)
Now if I try walk along a 9 inch wall 12 feet up my mind is telling me this is dangerous and I get a cease and desist order from the brain after all it’s trying to protect me!
My friend has broke that fear and can freely walk do some mad things
If you have an equal amount of room then physically there’s no difference. However if you have no perceptual references, compounded with the nerves that come with standing above an infinite void, balancing becomes very difficult.
Your mind…
If people but on a VR headset and are told to walk over a beam they have the same issues.
Search for some “VR plank” videos and you will see people have trouble walking on a level floor if their perception is of a beam over emptiness.
Lets leave the psychological components out of this for a moment. I have worked in a circus. All acts basically require the ability to balance. Every artist will tell you that they balance according to sight. Which has often lead us to put reflecting tapes, pointed markers, set up lights, what have you, so that the artists can find a spot to focus on during their act, which is what they use to stay in balance.
Our sense of balance has a lot to do with our sight, especially when we are moving. We choose a point of refrence and focus on that, then from that we get additional information about how we are moving and use that to adjust our balance. Try walking downhill blindfolded, it is really hard.
So as long as you choose a point in the distance to focus on, you can easily walk on quite narrow paths.
This is a trick which helped me a lot when I worked as a welder installing scaffolding at a shipyard. The platform pieces were 300mm wide. And when assembling the tall scaffolding the levels were
usually made of 2×2 meter squares, and had two platforms on both sides lenght wise. You quickly learned to walk on these and the trick was look forwards, not down.
Funnily enough the one time I had never struggled to balance was when I welded.
If you go with confidence, keep your head level and look forward to a point, you keep your balance. But even the best balance artists will struggle to stay upright without a point to focus on. Which is why true blindfold tricks are hard and rarely done.
Used to work on roofs putting up tv aerials,sometimes walked on ridges etc.Was told by the guy training me,don’t think about where you put your feet,think about where not to put your feet.He also said that falling off a roof isn’t painfull,it’s the stopping at the end of it that hurts.
The impact of failing is likely a cause of the nervousness. Shoot at an apple on a wall – you’d probably give it a go without too much thinking. Now put that apple on the head of someone you love – the impact of you missing is now MUCH greater – you’re going to get nervous as the cost of failure went WAY up.
The cost of failure at height is your entire life. On the street, MAYBE a twisted ankle at best.
A lot would have to do with perspective. Your eyes can perceive the ground around a beam if it’s laying on the ground without having to strain your eyes at all. If you’re fifty feet in the air then when your eyes try to see the ground it’s out of focus because the perspective between the close beam and the far ground is way off and your eyes are constantly changing to try to make the picture work together. Your brain can’t figure out what’s going on and it makes it really hard to balance on the beam in front of you unless you really focus on just the beam and ignore anything else.
Although walking on a street is very very safe there is still a chance of tripping but because tripping when in the ground already is unlikely to do any damage you don’t see it as much of a risk. When on a beam above emptiness the risk of you tripping might be the same but the consequences of you doing so is much greater so it makes it much more stessfull.
