Virtual Reality's Applications In Healthcare

The term “virtual reality” (VR) is often associated with various forms of entertainment, such as video games and streaming movies. However, the unseen side of virtual reality is transforming healthcare, education, and even the economy for the better. Psychologist Jeremy Bailenson explains that virtual reality creates a consuming feeling called “presence”, which tricks the brain into believing that virtual environments are real, leading to the immersive nature of VR (Mado and Bailenson 163). This immersive quality is what allows VR to have benefits, beyond futuristic entertainment, in training, education, and treatment. An example of this can be seen through a study conducted at the University of Washington by Hunter Hoffman and his colleagues, “People with burn injuries experienced up to 44% less pain when using VR because the immersive environment was such an efficient distraction” (Vergos). VR was first developed in 1968 by Ivan Sutherland and Bob Sproull, who created the first head mounted display system, called the “Sword of Damocles” (Vergos 428). Since then, VR has greatly developed and changed to become the beneficial tool it is today. Virtual reality is a recent innovation in the field of education, healthcare, and the economy. An analysis of the positive and negative impacts of this technology results in the conclusion that virtual reality has more benefits than traditional methods, but the future of this tool depends on accessibility, affordability, and ethics.

Virtual reality has been proven to have various positive benefits on medicine, education, and the economy. In the medical field, virtual reality offers a more effective and personalized alternative to traditional treatment methods. For example, doctors at St. Jude are using virtual reality to distract patients during painful treatments. It works by keeping the brain busy, helping reduce the feeling of pain, and lowering the need for opioid medications ("Using Virtual Reality"). This approach illustrates the power of VR’s immersive qualities, which engage a patient’s senses to the extent that they are completely distracted from their pain. Virtual reality offers an alternative to traditional methods of pain treatment, which often do more harm than good, seen through the opioid crisis. As one policy analysis points out, “For individuals addicted to opioids or suffering from chronic pain, a war on drugs has never been a prescription for improving wellness...” (Bowers and Abrahamson 3). This highlights how opioids are often overprescribed and can lead to serious long term risks, ones that VR pain management avoids completely. Additionally, the statistic that patients can experience up to 44% less pain as a result of virtual reality reveals that it is more than just a distraction, but a legitimate pain management tool. This also shows the potential of VR in becoming a standardized part of patient care, especially in pediatric or chronic pain cases, where traditional methods or prescriptions for pain are not ideal. Through offering a safer and more engaging alternative, virtual reality is transforming how pain management is approached in healthcare. 

In addition to benefitting medicine, virtual reality can improve education by providing more engaging, realistic, and unique methods of teaching than traditional textbook learning. Many classrooms rely on traditional forms of learning, such as using textbooks or listening to long lectures, which have limited success in truly teaching students.Virtual reality offers a way to overcome this barrier, by simulating engaging learning environments that fosters a deeper understanding of content. An article authored by Hyunkyung Sung and his colleagues analyzed 45 studies to reveal that VR-based education in healthcare significantly increased students’ knowledge and skills, increased confidence and satisfaction, and helped them complete procedures faster than traditional methods (Sung et al.). These results display VR’s power to improve academic performance, especially during training for careers that require precision and hands on practice. Allowing students studying the healthcare field to interact with 3d models and respond to emergencies in a risk free environment helps them hone their skills before performing in the real world. 

Finally, virtual reality has the power to enhance the economy by making education and job training more accessible and beneficial in many industries. In today’s modern world, many jobs are now taking advantage of remote options for both working and training. Virtual reality makes it possible for employees to complete job training and interact with tasks without being there in person, using physical space and materials. Researchers Simpson Poon and Shri Rai analyzed the presence of online technologies in the field of global business. They concluded that “although online technology promises to offer an independent learning environment anytime and anywhere, only some aspects of the technology are useful depending on the nature of the task... A challenge faced by online education providers is to find the right mix and how to come up with a framework that will provide optimal results,” (Poon and Rai). Their conclusion explains that if the correct framework and logistics for job training can be formed by online education providers, virtual reality has the potential to offer immersive experiences that traditional job training simply cannot achieve. Additionally, it is cost-effective as it takes away the need for in person workshops and materials. Overall, virtual reality strengthens the economy by providing an immersive and accessible way to improve job training. 

The implementation of virtual reality comes with negative impacts, especially in the field of medicine, education, and ethics. The highly immersive aspect of virtual reality may cause health risks for vulnerable patients, such as those with psychological conditions. A study conducted by Giovanni Albani and his colleagues was published in the journal Parkinson’s Disease. The study followed 23 Parkinson’s patients over eight years, and found that those who experienced visual hallucinations (VH) during immersive VR sessions later developed similar symptoms in real life, suggesting VR may trigger or predict hallucinations in neurologically vulnerable users (Albani et al.). This conclusion brings a significant risk of virtual reality in medicine to light. The immersive nature of VR can lead patients with cognitive or neurological deficits to confuse reality and can alter their perceptions completely. This risk is especially prevalent because the effects are delayed, meaning the effects of VR on these patients can go undetected and leave long term effects on their mental health. Overall, while virtual reality has shown benefits in improving healthcare, it should be implemented carefully to avoid unwanted, harmful long term effects. 

Although virtual reality shows potential in enhancing education, poorly designed virtual environments can frustrate or overwhelm students, causing their academic performance to decline. According to a study conducted in 2009 by DeStrulle, “Options for interaction were confusing within the virtual environments, leading to cognitive load issues and frustration in participants, and the mix of audio, text, colors, movement, and navigation tools were together found to distract from learning” (de Strulle, 2009). This shows that if virtual environments are not properly designed to the student’s needs and capabilities, it can overwhelm students rather than engage them. Virtual reality environments often contain many sensory stimuli that can increase stress in students, therefore decreasing their retention of information and academic performance. This occurs when educators fail to align the technology with specific goals, and in these cases traditional learning may be more effective. Virtual reality has shown benefits in the classroom, but misusing the technology can cause confusion and stress, limiting its effectiveness. 

While virtual reality provides exciting opportunities, its implementation comes with serious ethical concerns.Virtual reality's immersive nature causes concerns about ethics, as users may have trouble distinguishing between reality and the simulation, making them vulnerable to manipulation. Jenna Ng explains that VR blurs the line between real and virtual by removing noticeable screen boundaries, causing users to lose awareness of where one ends and the other begins. This creates a mental and sensory state where individuals are fully absorbed, potentially impairing critical thinking or awareness of manipulation (Ng 108–116). This level of immersion especially affects vulnerable users, such as younger individuals, who have trouble separating fiction and reality. As users become more vulnerable to manipulation, VR can subtly influence their mindset on certain commercial, political, or psychological concepts, without the user knowing it. While the immsersive nature of VR is part of what makes it so influential, it also causes ethical concerns that should be addressed in the design of the virtual environment. 

After analyzing the benefits, drawbacks, and future impacts of virtual reality, it can be concluded that its overall impact is largely positive. According to Poornima Padmanabhan, there are possible adverse reactions to virtual reality, such as cybersickness, visual effects, neural effects, and psychological effects (Padmanabhan, 2008, p. 274). However, these risks can be mitigated through careful use and design of virtual environments. When implemented properly, virtual reality can even positively benefit emotions. As Madary and Bailenson explain, "Virtual embodiment can be used to encourage 'walking in the shoes of another'... studies suggest that embodied experiences in VR are more likely to increase involvement or empathy," (Madary & Bailenson, 2018, p. 163). This can be transformative in social justice and therapy settings. Additionally, VR is completely transforming the way students learn. According to Sandra Helsel, virtual reality can shift education away from textbook based learning, and towards engaging, hands-on experiences in virtual environments. An example of this is being able to interact with historical figures through VR instead of reading about them in a textbook  (Helsel, 1992, p. 41). Finally, virtual reality has great potential in the field of medicine. Researcher Micheal Andrae discusses how VR is set up to support cutting-edge medical innovations, like controlling micro and nanobots for surgeries inside the human body. It will also transform how future surgeons train using advanced virtual simulations (Andreae 5). Overall, while VR must be used with caution, its significant benefits, particularly in education at all levels, display how it is a transformative tool for training, empathy, and innovation that will continue to grow. 

In conclusion, virtual reality, a recent innovation in the field of healthcare, education, and the economy, has proven to have more significant benefits than traditional methods, as long as accessibility, affordability, and ethics are taken into account. Although risks such as negative psychological impacts, confusion between reality and fiction, and health problems exist, they are far outweighed by VR’s potential to enhance teaching, medicine, and workplace training. When compared, the power of VR’s benefits greatly exceeds its drawbacks. Embracing this technology and utilizing it to its full potential can lead to breakthroughs that would completely transform our world for the better.
