To have a '''head for heights'''  means that one has no [[Medicine:Acrophobia|acrophobia]], an irrational fear of heights, and is not particularly prone to fear of falling or suffering from [[Medicine:Vertigo|vertigo]], the spinning sensation that can be triggered, for example, by looking down from a high place.

A head for heights is frequently cited as a requirement when mountain hiking or climbing for a particular route as well as paragliding and hang-gliding. It is needed for certain jobs, such as for [[Physics:Wind turbine|wind turbine]] technicians, chimney sweeps, roofers, steeplejacks and window cleaners.

Unlike acrophobia, a natural fear of falling is a normal phenomenon. When one finds oneself in an exposed place at a great height, one feels one’s own posture as unstable. A normal fear of falling can generate feelings of anxiety as well as autonomic symptoms like outbreaks of sweat.

== Causes of fear of falling ==
There are logical biological causes of fear of falling. Firstly, there is the innate so-called "cliff edge phenomenon", whereby even toddlers, as well as many animals, avoid large drops, even without having previously had a bad experience.<ref name=Brandt>[https://books.google.com/books?id=dFevxJ0mJncC&dq=%22distance+vertigo%22&pg=PA418 ''Vertigo: Its Multisensory Syndromes''] by Thomas Brandt (2003), p. 422.

[[Medicine:Vertigo|Vertigo]] itself is caused by a destabilization of the posture which, when it occurs at height, results from too large a distance from the eyes to the nearest visible solid object and is referred to as "distance vertigo" or "height vertigo". In order to see the object in space, the head starts to sway imperceptibly and "location reflex" then causes the body to sway with it. At the same time, the body stabilizes its position using the periphery of the [[Biology:Retina|retina]], but when someone looks down they now lack this stabilizing factor. This [[Biology:Physiology|physiological]] swaying is normally counteracted by the body's [[Biology:Vestibular system|vestibular system]] and [[Biology:Proprioception|proprioceptive]] sense. However, for example, if there is damage to the [[Biology:Sense of balance|sense of balance]], in fact, the risk of falling is increased.
