Feasibility and preliminary efficacy of an intervention combining hypnosis and virtual nature exposure in patients following hematopoietic cell transplantation
This randomized feasibility trial demonstrates that a combined hypnosis and virtual nature exposure intervention is safe and well-received by hematopoietic cell transplantation patients, yielding significant immediate reductions in anxiety and fatigue, though no long-term group differences in quality of life were observed at one and three months.

For patients facing a hematopoietic cell transplant, the path to recovery is often paved with physical pain, deep fatigue, and the psychological weight of isolation. This medical procedure, which replaces a patient's diseased blood-forming cells with healthy ones, requires a period of intense treatment followed by strict quarantine to protect the immune system. While the transplant offers a chance at a cure, the journey itself can be grueling, leaving many survivors with lingering cognitive fog and emotional distress. In recent years, doctors and researchers have turned to non-drug methods to help ease this burden. Two such approaches have shown promise: hypnosis, a state of focused attention that helps the mind respond to calming suggestions, and virtual reality, which uses a headset to immerse a person in a simulated environment. When combined, these tools might offer a way to guide a patient's attention away from discomfort and toward a sense of peace, potentially using the calming power of nature to help the mind rest.
A team of researchers from several hospitals and universities in Montreal set out to test whether combining these two methods could work for patients immediately following their transplant. They designed a study to see if the approach was practical to use in a hospital setting and whether it offered any immediate relief from symptoms like anxiety, pain, and exhaustion. The researchers recruited forty adults who had recently undergone the procedure. Half of the participants were assigned to a control group that received standard medical care, while the other half entered an experimental group. These participants were given a tablet application that allowed them to explore virtual landscapes—such as forests or beaches—while listening to guided hypnosis scripts. They were encouraged to use the system on their own for two weeks, aiming to visit these digital environments at least three times.
The study focused first on feasibility: could the patients actually use the technology without getting sick or frustrated? The results were encouraging. The participants in the experimental group used the application an average of nearly three times over the two-week period. Very few reported feeling dizzy or nauseous, a common side effect known as cybersickness, suggesting the technology was gentle enough for people in a fragile state of health. When researchers spoke with the participants afterward, the feedback was largely positive. Many described the experience as a welcome escape from the hospital room, noting that the combination of natural scenery and calming voices helped them feel less anxious and less isolated. Some mentioned that the virtual nature scenes provided a sense of space that the hospital walls could not offer.
However, the study also revealed important limitations regarding how the intervention worked over time. While the participants felt an immediate sense of relief right after their first session—reporting lower levels of fatigue and anxiety and feeling more relaxed and amused—these benefits did not necessarily last for weeks. When the researchers compared the two groups at one month and three months after the transplant, they found no significant difference in overall quality of life, pain levels, or long-term anxiety between those who used the virtual nature tool and those who did not. The data suggests that while the intervention offers a powerful, short-term boost to mood and relaxation, it may not be enough on its own to change the broader course of recovery over several months.
The researchers concluded that the combination of hypnosis and virtual nature exposure is a feasible and safe tool for patients undergoing this difficult treatment. It appears to be a useful way to provide immediate psychological comfort, acting as a temporary respite from the stress of the hospital environment. Yet, the study also highlighted that for such a tool to be most effective, it may need to be introduced with more guidance. Participants suggested that having a researcher or nurse present during the first few sessions to explain the technology and troubleshoot any issues would make a significant difference. They also noted that the timing of the sessions matters, as the first week after treatment is often too physically exhausting for patients to manage the technology on their own. Ultimately, this work points toward a future where digital tools might be integrated more carefully into patient care, offering a moment of calm in the midst of a challenging medical journey, provided the implementation is tailored to the specific needs and energy levels of the patients.
