Virtual reality can help act as a do-it-yourself therapist, helping people overcome their fear of heights without a professional at their side, British researchers reported Wednesday.
A half dozen virtual reality sessions over two weeks significantly reduced the fear of heights for more than two-thirds of people who tried it, the team at the University of Oxford reported. Some even ventured onto rope bridges and mountainsides.
“The outcome results are brilliant. They are better than I expected,” Daniel Freeman, the University of Oxford clinical psychologist who led the study team, told NBC News.
The team tested 100 volunteers, 49 of whom were given six virtual reality sessions over two weeks. The rest got no treatment.
On average, the volunteers had been afraid of heights for 30 years, the team reported in the journal Lancet Psychiatry.
After six weeks, those who got no treatment remained just as afraid of heights as they had always been, as measured by a standard questionnaire. But 34 of the 49 volunteers who did the virtual reality found they were no longer afraid of heights.
Real-life exposure to heights has verified this, Freeman said.
“On average, fear of heights came down by two thirds. Three quarters of people showed at least a halving in their fear of heights,” Freeman said.
“Afterwards, people even found they could go to places that they wouldn’t have imagined possible, such as walk up a steep mountain, go with their children on a rope bridge, or simply use an escalator in a shopping center without fear.”

The software can be whimsical, offering scenarios from walking across a virtual rope bridge to rescuing a cat from a limb. Freeman said the experiences are meant to strongly immerse people in a sensation of height and then encourage them to challenge their reluctance to take part.
The virtual therapist talks the patients through, using cognitive therapy techniques to alter their perception of the experience.
Freeman says his team is trying the approach to help a range of mental health conditions, including schizophrenia.
“VR has extraordinary potential to help people overcome mental health problems because it gets to the heart of successful treatment: making people feel better in everyday life,” he said in a written statement.
“In VR, people can repeatedly enter simulations of the everyday situations that trouble them and be guided in the very best ways to think, feel, and behave.”
Virtual therapy had been used before to help people overcome a fear of heights, but always with the guidance of a mental health professional, Freeman said. The virtual reality was more of an aid than a treatment itself.
Not everyone has access to that kind of care and not everyone wants to go see a therapist, he said. Virtual reality software, with high-quality equipment, could help more people.
“There are too few skilled therapists delivering the best treatments to meet the high demand, meaning that millions of people are left waiting for the right help,” Freeman said.
