VIRTUAL REALITY A GREAT PROMISE IN ADDRESSING STRESS

to feel as if they are in the traumatic scenario.
Riding a wave of interest in mental health technology, companies creating VR content for therapeutic outcomes are receiving a deluge of attention and funding. And, while VR has been used successfully to treat post-traumatic stress disorder (PTSD) since the 1990s, these new programmes address a much broader range of conditions.
Research has shown how heart rate, facial muscles, electrodermal activity (EDA/GSR), respiration, and other aspects of physiology are reliably impacted by fearful responses. By quantifying these responses in a virtual environment, researchers can get a better idea of what induces fear, and which components are critical for alleviating the fear response.
The role of Virtual Reality (VR) in managing anxiety has been a growing dimension of the healthcare industry as demonstrated by the growing use of technology – along with augmented reality – to create cost-effective and repeatable training courses for surgeons. In physical and cognitive therapy, too, VR shows great promise.
Today’s VR content is primarily designed to aid exposure therapy, a treatment for anxiety disorders in which patients are exposed to anxiety, inducing stimuli in a safe, controlled environment, eventually learning that the ‘threats’ they’re worried about are not actually very dangerous. For example, someone who fears heights might visit progressively taller buildings under the guidance of their therapist (in vivo exposure), while someone with PTSD might revisit traumatic memories in therapy sessions (imaginary exposure).
The use of biosensors has also provided promising results for using VR alongside conventional therapy. Individuals with general anxiety disorder have been found to exhibit differences in their level of electrodermal activity, which could be used to provide information for judging therapy success.
A new wave of psychological research is pioneering VR to diagnose and treat medical conditions from social anxiety to chronic pain to Alzheimer’s disease. Many of these solutions are still in the laboratory stage, but some are already making
Although medications and talk therapy can help calm the symptoms of PTSD, the most effective therapies often require confronting the trauma, as with virtual-reality-based treatments. These computer programmes, similar to a video game, allow people
Anxiety symptoms can cause significant distress, impair quality of life, and increase stress. Anxiety increases risk for a range of co-occurring physical conditions, including chronic pain. Given the pervasiveness of anxiety and its impact on mental and physical health, effective treatment is clearly needed, yet a majority of affected individuals remain untreated.

A new study published in the Journal of Medical Signals and Sensors has added to the research volume in this area showing that virtual reality (VR) can be helpful in treating claustrophobia. The software in this study simulated an elevator moving to the tenth floor and also a magnetic resonance imaging (MRI) device. Researchers found that it was helpful to reduce anxiety and was accessible and easy for people to use it. The study also examined different dimen-
