Intrusive thoughts happen when people are going about their everyday life and are usually related to a past trauma, Hames said. But for HPP to occur, a person usually has to be the particular setting, like a cliffside or ledge. High Places Phenomenon explained. Best value. Study participants have been observed to overestimate verticals by anywhere from one-third bigger to double their actual size. The vertical over-estimation bias makes high places scarier than they are for some people: Stefanucci and others have found that people most afraid of heights overestimated verticals the most, heightening their fear and creating a feedback loop.
Steep drop-offs in high places can also create symptoms related to motion sickness because of conflicts between our visual system and our vestibular system, Coelho hypothesizes. The conflict creates nausea.
It can help to close your eyes. Something similar can happen on a high precipice. Perhaps a mountain pass in the Pyrenees, like where Sartre used to vacation, possibly inspiring his famed urge-to-leap passage in Being and Nothingness , according to Sartre biographer Gary Cox.
The view seems to stretch forever, the distant expanses flattening into infinity. With so little earth up close beneath your feet, there are few visual cues to accompany forward motion, and your visual and vestibular systems clash. Those who are most likely to feel the urge to leap also tend to worry more about other life issues.
People who rely more on sight to navigate struggle harder to maintain their balance while moving, making them even more afraid at heights, where the loss of depth of field confounds our visual abilities. Others may suffer from poor postural control, which requires muscular-skeletal strength and agility. Coelho measures postural control in his laboratory with the Romberg test, echoed in the drunk driving check requiring you to walk a straight line. To try the tougher lab version, stand barefoot heel to toe, left foot directly in front of the right, cross your hands over your chest, and close your eyes.
Now hold that pose for two minutes. Sounds easy, right? Many people only make it a few seconds. The few aces who made it to two minutes were the least afraid of heights. The difficulties presented by these effects—faulty visual perspective, poor body control, weak vestibular signaling, and overestimation—contribute to making acrophobia, or fear of heights, one of the most common phobias in the world, affecting 1 in 20 people.
But unlike snake, spider, or blood phobias, acrophobia can produce a bizarrely counterintuitive effect: the impulse to yield to the source of panic and willingly jump. A s complex as our fear of heights is, the urge to jump is even more difficult to explain. Our fear circuitry, which includes the amygdala and other fast-acting subconscious brain regions, may send an alarm to the prefrontal cortex for interpretation.

Research has shown the benefits of mindfulness, but the current mindfulness craze cannot deliver on its overhyped promises. Some scientists believe that DMT could revolutionize the treatment of depression. Psychedelics have been shown to help reduce depression. This study may show us why.
