Now, a growing number of researchers and hospitals have also found that VR can reduce the anxiety and pain associated with drug change, intravenous injection or epidural administration.

It can also help patients relax before and after surgery.

Last march's cedars-sinai study, involving 100 hospitalized patients, found that those who had seen a quiet video on their VR head reported a 24% drop in pain scores.

Another 50 patients watched the standard 2-d natural video on a nearby screen, reducing the pain by only 13.2%.


Brennan Spiegel, director of the cedars-sinai health service in Los Angeles, says they are still not sure why VR is so effective in reducing pain.

"The brain is so complex that it's hard to know how virtual reality works," Spiegel says.

But simple distractions are thought to be at work: the brain is busy processing signals from VR, so it's hard to deal with other signals, such as pain.
