There is some evidence that virtual reality can help ease chronic pain. In particular, studies have shown that it can be effective in reducing pain levels and in improving quality of life.
One reason why virtual reality may be helpful for chronic pain is that it can provide a distraction from the pain. This is because when people are engaged in a virtual reality experience, they tend to focus on the task at hand and not on the pain. As such, it can serve as a form of cognitive distraction.
